Abandoned land reclamation planning in coastal area in North-East of China

The damaged environment is a global problem. It is more serious in China because of the cultivable land destroyed. So the agroecosystem reconstruction is the primary object in China. A case of reclamation planning in LiaoNing Province was studied in this paper. A large number of abandoned land sites have become an urgent task for the local government since farmland is so short in this area. The land suitability and usage should be determined before the land reclaimed. Based on land-use mathematical models and software MATLAB 6.0, optimum land-use structure should fit for local ecological and economic requirement. The horizontal, vertical structure and food chains of the system should be considered. Ecological engineering was used to planning as the shelter-forest, farmland and livestock farms. Irrigation work was designed to remove the salt. The forestry, fishery, poultry breeding were set up after rehabilitation. Therefore, the regional environment can get a great progress and their economy will have a sustainable development. Additional
