Research On District Sustainable Development And Decision Support System

A district is a complicated system composed of close related society, economy,and ecosystem that are interactive, dependent and restrictive. The establishment andimplementation of the district sustainable development strategy involves a lot ofcomplicated factors, and the decision-making is more strategic, essential and risky.This thesis, by analyzing the related factors of the district Sustainable developmentdecision-making, focuses on the establishment of the district sustainable developmentsystem and studies the district sustainable development theory and the decisionsupport system.The first part deals with the district sustainable development theory. Based onthe compound ecosystem theories,it studies the structure, function and balanceconditions of the ecosystem of district compound system, and the inner regulations ofsystematic development of ecosystem of the district.The second part deals with the decision-making of the district sustainabledevelopment. The thesis, by analyzing the related factors of the district sustainabledevelopment decision-making, focuses on the establishment of the district sustainabledevelopment system, and puts forward the principles and the aims of the districtsustainable development decision-making.The third part deals with the evaluation theories and evaluation systems of thedistrict sustainable development. The scientific and feasible evaluation can providethe important gist for the implementation of the district sustainable development. Weuse the AHP method, entropy analyses method, grey correlation method, and fuzzyevaluation method to judge and measure the level, the capacity and the dynamictrends of the sustainable development for decision support.The fourth part deals with the strategies and countermeasures of the districtsustainable development. On the basis of the studies and analyses of the environmentand foundation of different districts in implementing the sustainable development,and on the basis of studies and analyses of the pressure and disadvantages confrontedby the strategic implementation, it puts forward the district sustainable developmentstrategies and countermeasures, using the BP model of neural network to givetechnical support for the strategies and decisions of the district sustainabledevelopment.The fifth part deals with the computer software that provides the decisionsupport system of the district sustainable development. By using the computertechnology, it builds up the management information system, technology supportsystem, and geographic information system. The systems, adopting the open design,provide services for the sustainable development decision-making of the district.
