Sustainable Development Assessment Of Poyang Lake Area Water Resources

Poyang Lake is one of the seventh important wetlands in the world's and is the largest. throughput fresh water lake in-China,with the rapid s0cio-economic development,the consumption of water in Poyang Lake Area soared,and more and more serious water pollution, the environment has been damaged,directly affect the sustainable development of the area,so it is essential to,examine this area of Poyang Lake sustainable development of water resources,To evaluate Poyang lake area of water resources sustainable.development.by,the establishment of Poyang Lake area of sustainable development indicators system.First of all,the paper on the issue put forward preconditions for research background, sustainable development of water resources connotation.Summing up the sustainable development of water resources evaluation;method at home and abroad,and analysis the main problems on it,and discuss the direction development in future;Second,Elaborated on the profile of the Poyang Lake area;Then construct indicators system of water resources sustainable development in the Poyang Lake area,have established it by Poyang Lake area special. conditions and sources of information,establish the index system on four-level indicators of goals layer,layer.criteria,the criteria,level;Determined the weights of indicators system index at-all levels by using the method of combining AHP and expert advice,through expert advice score obtained judgment matrix,and its largest eigenvalues and eigenvectors use Matlab software programming to handle calculation;At last,this paper use 2000 as the base year,Calculation the coefficient of water resources sustainable development in 2001 to 2005,evaluation results are quasi-sustainable development,which in 2003-is weak sustainable development,analysis the existing problems on it,and propose the corresponding recommendations.Currently,the lakes regional sustainable development of water resources is still in-the initial stage of research at home and abroad,and study less.It can comprehensive and in-depth reflect the level development of water resources systems as well as its social,economic, ecological environment system coordination situation,fair degree;by establishing index system-and evaluating its indicators in quantitative.This regional water resources strategy of sustainable development has an important theoretical and practical value,but it is also monitoring, assessment,control and planning basis.
