Ecological Green Wedge

Ecological green wedge refers to the large ecological land wedged into the city from the outer area of the city, and its shape changes from wide to narrow. It can introduce suburban ecological resources into cities, and alleviate urban heat island effect to improve the urban ecological environmental quality. In addition to its ecological function, the ecological green wedge is also used to isolate different city groups, or separate the old city from the new city, and then "spreading the pie" can be prevented. In the ecological green wedge planning area located at the edge of the city, there are abundant natural ecological resources such as mountains, water systems, wetlands, woodlands, farmland, lakes, etc. These resources are easily destroyed in the rapid urbanization process. Urban green development requires that ecological green wedge should not only delineate the boundary, but also initiate ecological restoration and construction task as soon as possible to protect the existing valuable resources.
