Study On Methodology Of Assessment For Water Resources Carrying Capacity In Different Zones

Water resources carrying capacity(WRCC) based on conflict between the scarcity and the rapid growth of population and economy is brought forward for 20 years. The study will give some suggestions to the region planning and development mode analysis.The paper puts forward the appraised method and makes the example analysis. Itcan be divided into three parts:The first part(the 1,2 chapter) mainly summarizes water resources achievement,concludes the concept,connotation and characteristic,classicfies the appraised method into experience estimate method, index system appraised method and complex system analysis method. Then points the merit and the defect, the exsited problems. At last, the paper brings forward the characteristic of the appraised self-method.The second part(the 3,4 chapter) mainly introduces the method. Based on the water resources concepts, the paper analyzes the principal part, the objects, the coupling under the water resources collocation, and puts forward the three hierarchies index system. Then the grades of WRCC levels are assorted to subsistence, being better off, basic modernization and the modernizaion, and the method is pionted out.The third part(the 5.6 chapter)takes Dongying city,Hainan province,Haihe river basin and Shiyang river basin for example to caculate, and compares their three hiberarchies indice. Besides, the Dongying city is taken as the emphasis for scene-caculation. The results suggest that although the apprasied method is simple, it has the clear hiberarchies and good practicability. The conclusion points out the innovation and deficiency of the study, and the study direction of WRCC in the future.
