Author：WANG Guoyu; BAI Weilan; XIONG Xiao; MU Xiaohong; QIU Litao

ABSTRACT: The ecological space of urban agglomerations plays an important role in sustainable regional development. This paper takes the ecological space of the Beijing-Tianjin-Hebei Urban Agglomeration （BTHUA） as the research object, and a method for identifying the damaged ecological space system of urban agglomerations is established. Typical source and corridor types of ecological space are identified by multi-period and multi-source image data, and the ecological space damage and spatial distribution are analyzed. The evaluation results of ecological space damage in BTHUA region from 1995 to 2015 showed that 66.94% of the ecological source and 39.76% of the ecological corridors were damaged to different degrees. From the perspective of spatial pattern, in cities such as Beijing, Tianjin, Baoding, and Langfang, the core functional areas of the central urban agglomeration, moderately damaged and severely damaged types account for more than 90% of the total area of typical ecological spaces; in northwestern ecological conservation area, such as Zhangjiakou and Chengde, the proportion is less than 50%. In view of the above problems, this paper puts forward measures and suggestions for the restoration of ecological space and points out the enlightenments for the urban agglomeration spatial planning during the "14th Five-Year Plan" period, in the hope of providing reference and support for the coordinated development of Beijing-Tianjin-Hebei region.

♦ A STUDY ON MULTI-SCALE HUMAN SETTLEMENTS EFFECTS OF RICE FARMING SETTLEMENTS ON THE SOUTHERN BANK OF YUANJIANG RIVER

Author：YANG Yuliang; LUO Dan; JIAO Yuanmei

ABSTRACT: Aiming at the disciplinary division of the research on rice farming settlements, the author starts with the elements of human settlements at different scales, and conducts research on three "nested" spaces of different scales: Yuanjiang River Basin, Dawazhe River Basin, and ethnic minority settlements. The purpose of this article is to clarify the typical characteristics of multi-scale space and its impact on the human settlement environment. Research shows the following facts: the basin level has the spatial characteristics of "mountain parallel with water, and water parallel with water", and the effect of "balanced distribution"; the subbasin level shows the spatial characteristics of vertical difference and the effect of "stratification and heterogeneity"; and the settlement level has the "heterogeneous pattern" effect shown by the differentiation of ethnic villages. The research conclusions are as follows: "nested" spaces of different scales are closely linked through humanland interaction; there are significant differences in the "resolution" of human settlements at different scales, and multi-disciplinary research methods that run through multiple scales must be adopted.

♦RESEARCH ON THE INNOVATIVE NETWORK OF GUANGZHOU, DONGGUAN AND SHENZHEN IN THE CONTEXT OF THE GUANGDONG-HONG KONG-MACAO GREATER BAY AREA DEVELOPMENT

Author：QIU Yanqing; ZHONG Ye; LIU Pei; REN Qingchang

ABSTRACT: In the upsurge of building the Guangzhou-Shenzhen Technology and Innovation Corridor in recent years, this paper explores the innovative network pattern of Guangzhou, Dongguan and Shenzhen in the context of the Guangdong-Hong Kong-Macao Greater Bay Area development by focusing mainly on the external and internal innovative links between cities along the corridor and based on two kinds of data: headquarters-branch links of high-tech enterprises and patent cooperation data from Wanfang platform. On one hand, the paper analyzes the external innovative network of Guangzhou, Dongguan and Shenzhen from the regional level, finding that more than three-quarter innovative links are related to Guangzhou, Dongguan and Shenzhen in the Greater Bay Area, and largely concentrated in the east part of the three cities; and that the innovative links between Shenzhen and Dongguan and between Hong Kong and Guangzhou/Dongguan are stronger than those with Macao. On the other hand, it analyzes the internal innovative connection pattern among the towns of Guangzhou, Dongguan and Shenzhen, finding that the frequent contact areas of the three cities are generally concentrated in the main urban areas, the surrounding areas of high-tech zones and the urban adjacent areas where high-tech industries and manufacturing industries gather. In addition, Guangzhou's innovation is relatively inward, while Shenzhen's innovation outward degree and driving force are obviously better. Based on the external and internal innovative network of Guangzhou, Dongguan and Shenzhen in the context of developing the Greater Bay Area, the paper summarizes the characteristics of topological network and further analyzes the mechanism of innovative network. Finally, it puts forward suggestions for promoting Hong Kong and Macao coordinated development, improving the network and system, and implementing policies based on local conditions.

♦ RESEARCH ON THE PREPARATION OF THEMED URBAN COMPREHENSIVE DESIGN: A CASE STUDY OF NANJING

Author：WANG Jianguo; YANG Junyan; CHEN Wei

ABSTRACT: In recent years, with the reform of territorial planning system, the tasks of territorial planning and comprehensive urban design have been clearly distinguished. Different from the comprehensive, strategic, coordinated, basic, and binding nature of the territorial plan, the comprehensive urban design should be based on the local natural and cultural endowment. It should focus on the protection of natural and historical and cultural heritage, study the urban space order control and guidance scheme, to improve the quality and value of land and space. The comprehensive urban design of Nanjing starts from the three dimensions of "green", "culture", and "city". With the support of advanced technology and big data model, it analyzes the natural landscape characteristics, historical and cultural characteristics, and urban vitality characteristics of Nanjing. Based on this, this paper develops the urban charm space framework of Nanjing, and deduces the "nine methods of urban design" for the future development of Nanjing by referring to the traditional wisdom of Chinese urban construction and management. It forms a regular language control, and gives corresponding control measures from the system design and the location of specific characteristic areas. In the end, the overall framework and development ideas of Nanjing's future urban form are clarified, which provides the basis for the revision of Nanjing's territorial planning.

♦ EXPLORATION ON COUNTY SPACE FOR REALMS OF MEMORY IN THE OLD REVOLUTIONARY BASE AREA: A CASE STUDY OF THE HISTORICAL SITES OF ANTI-JAPANESE WAR IN LANXIAN COUNTY, SHANXI PROVINCE

Author：YI Xiaoya; HE Yi; DENG Wei

ABSTRACT：The cultural heritage in the old revolutionary base area has distinct event characteristics and has become historical memorial sites because of the occurrence and development of specific historical events. Due to the intensity and brevity of revolutionary events, only a few sites became the cultural heritage in the form of monuments. And the historical environment associated with the event itself is mostly lost in the vast space and time after the event. On the one hand, historical events cannot be "read" as a whole because they are separated from the specific environment; on the other hand, the fragmentation of historical information gradually blurs the historical significance. Based on the theory of realms of memory and taking the historical relics of the Anti-Japanese War in Lanxian County, Shanxi Province as an example, this paper analyzes the event characteristics and event environment of the old revolutionary base area in the county space unit. In the end, the research reconstructs the significance of historical events in the county space through the realms of memory, and explores the ways to protect and utilize the event-related cultural heritage.

♦ DECODING THE IMPACT OF POTENTIAL URBAN RISK FACTORS ON THE COVID 19 SITUATION: A CASE STUDY OF WUHAN

Author：LI Xin; ZHOU Lin; JIA Tao; LIU Feiyang; ZOU Yuliang

ABSTRACT：Wuhan is the city that was hit hardest by the COVID-19 epidemic. Based mainly on the data of confirmed cases in the central urban area of Wuhan, this paper comprehensively analyzes the distribution and spread of the epidemic in the central urban area of Wuhan by spatially processing the geographic location information of confirmed communities and using kernel density analysis to estimate the spatial distribution of the infected people. On this basis, the paper explores the correlation between the epidemic and spatial risk factors, such as population, urban morphology, urban facilities, and urban functions through subdividing the study area into uniform grids and based on the multi-scale geographically weighted regression model. It reveals the effects, scope of influence, and spatial heterogeneity of these factors, and proposes corresponding urban planning suggestions for future response to such public health emergencies. Through the analysis and verification of these spatial risk factors, it contributes to adopting effective urban planning and architectural design countermeasures in the future, and helps formulate more scientific and reasonable prevention measures.

♦REGENERATION PROCESS AND MECHANISM OF CULTURAL SPACE IN OLD CITY FROM THE PERSPECTIVE OF SPACE PRODUCTION: A CASE STUDY OF DAXINGGONG AREA IN NANJING

Author：SUN Shijie; XIONG Enrui

ABSTRACT: The regeneration of public facilities in the old city is related to the structure of urban public space and the quality of urban space. From the perspective of space production, this paper attempts to develop an analytical framework of the spatial regeneration process in old cities from the three aspects of interests, capital, and power. The paper summarizes the three stages of cultural space regeneration process in Daxinggong area, Nanjing which correspond to three spatial allocation processes, including policy allocation in the site selection stage, capital allocation in the development stage, and consumption allocation in the operation stage. In addition, it discusses the mechanisms of cultural space regeneration in old cities, including demand-driven mechanism, benefit allocation mechanism, and capital augmentation mechanism. With public interest as the main regeneration goal, the regeneration of public service facilities in old cities should be led by the government, and professional groups can play a bigger role. As regeneration projects in the old city are featured by diversified renewal goals, complex renewal processes, and diverse spatial types, the emphasis of spatial regeneration in the old city should be laid on interest assessment, capital integration, and improvement of public participation institution.

♦AN EXPLORATION ON WATER CITY MODEL BASED ON LANDSCAPE INFRASTRUCTURE: TAKING SHENGZE TOWN IN WUJIANG DISTRICT OF SUZHOU CITY AS AN EXAMPLE

Author：DAI Pengfei; SUN Zeyu; ZHAI Jun

ABSTRACT: With the gradual advancement of the national strategy of green and integrated ecological development of the Yangtze River Delta, the demonstration zone of the integrated development requires a kind of ecology-based infrastructure as the system framework for the formation, evolution, and development of regional integration, so as to coordinate the integrated development of production, living, and ecology. Like most of the towns in the demonstration zone, the Shengze Town in Wujiang District of Suzhou City has experienced such severe problems as increased environmental degradation, declining quality of life, and urgent needs for industrial upgrading in its transition from a traditional agricultural water town to a modern textile town. Therefore, based on the five characteristics of the ecology-based landscape infrastructure, and taking Shengze Town as an example, this paper takes the high, middle, and low polder land pattern of the traditional water town at regional, town, and neighborhood scales into consideration, and discusses the strategies and methods for building a new water city model that is characterized by urban-rural interaction and city-industry integration. This model is an exploration on solving water safety and environmental problems, revitalizing regional economy, and promoting the coordinated development of production, living, and ecology in new Jiangnan water towns, as well as an exploration on the green and integrated ecological development of the Yangtze River Delta.

♦ PRACTICAL EXPLORATION ON TOP-LEVEL PLANNING OF WATER SYSTEM IN PARK CITY: A CASE STUDY ON TIANFU NEW AREA

Author：WANG Bo; HU Bin; MU Qiu; RUAN Chen

ABSTRACT: Water is the source of life, and the relationship between city and water runs through the history of human civilization. In the new era of ecological civilization, the people-oriented and sustainable development value is more emphasized. At the same time, the new concept of park city also requires more attention to the unity of macro-safety view and macro-ecological view, and pursues the multiple transformation of ecological value. It is urgent to integrally conceive the relationship between city and water under the new social, natural, and technological development background. Only by respecting objective laws and making overall plans, can we prosper the city with water, live and work in peace and contentment. Taking Tianfu New Area as an example, this paper puts forward a new city-water relationship paradigm of "three respects & four coordination". With the five-dimensional top-level design of "water history, water security, water ecology, water economy, and water civilization", the water-related special planning can be guided horizontally, and the detailed design of ecological environment and waterfront space can be guided vertically, hoping this could provide reference for other cities.
