According to the actual situation of inning in Zhejiang,it puts forward the assumption of ecological inning evaluating system,chooses the specific evaluating indexes and elementarily establishes the ecological inning evaluating system.

Surface soil peeling off and technology of ecological reclamationand beforehand reclamation in coal mining area;

In the study of current situation of waste dumps and open pits of Huolinhe opencast mine,two ecological reclamation models of waste dumps were designed and the Borda method was adopted to sort the reclamation of numerous and scattered waste dumps,which can provide theoretical basis for the decision making of ecological reclamation in the mining area.

Mathematical model study on overall impact of Sanmenwan Bay reclamation project;

Influence of reclamation and deposition on flood storage capacity of Dongting Lake;

Study on effects of estuarine reclamation on flood control and erosion of riverbed in Shenzhen River;

Analysis on displacement and stress of bridge piles induced by inning project;

However,the inning and land use of the tidal flat have caused a decrease in biodiversity along the coast and the reduction of self-adjusting function of the ecosystem in the tidal flat.

More than 2/3 coastal zones are silting, and accumulation tidal flat about 33 333 hm2every year; in addition, the tidal flat resources are not be exploited and used adequately, so the potentialities of inning and exploitation the tidal flat is prominent.
