Wetland Area Holdings in the Yangtze River Estuary

Abstract

Wetland resource in Shanghai city is very abundant, and the contradiction between human development and land limit is very violent, so that the development and utilization of wetlands is inevitable. It’s an important way to reclaim wetland to solve the contradiction in Shanghai. Protection can not only take the natural state of wetlands to maintain, and should not be only one habitat model. This paper proposes wetland area balance principle. Then the feasibility of wetland area balance is studied, and wetland area-holdings is proposed as a new concept. Select Jiuduansha wetland, East Chongming wetland and Nanhui beach wetland as examples, the processes of estuarine wetlands development and silting up are studied, research shows that the principle of area balance can be achieved in Yangtze River Estuary.
