Study On Water Resources Carrying Capacity In Typical Karst Drainage

Water resources carrying capacity is a foundational topic in water resources security strategic study and the foundational measurement of water resources security. It is an index which refers to the system of society, resources and environment. It reflects the supporting ability of the water resources system for sustainable society development, and it is an important issue in the field of water resources research and sustainable development. In practice domain, water resources carrying capacity is a basic theory of the regional water resources exploitation. Therefore, by researching the region water resources carrying capacity, we may understand the supporting function of the water resources system for social development, harmonize developmental relationships among the population, the resources and the entironment, also we can realize the social sustainable development better.But at present ,the study on water resources carrying capacity in civil and at abroard is mostly based on the non-Karst drainage ,on the basis of the studies before ,this paper gives the preparatory study on water carrying capacity of Karst drainage.Water resources science theory is applied in this paper. By using qualitative and quantitative analysis methods, and with the aid of computer technology (Microsoft Excel), statistical analysis software (SPSS 12.0), system theory, the supplying and demanding of water resources of Houzhai Catchment in pudding is forecasted and discussed. And then, water resources carrying capacity in Houzhai Catchment is evaluated in subarea and classification with the principal Component Analysis and Oslulation value Method. Furthermore, water resources carrying capacity in Houzhai Catchment is calculated and evaluated in actual and theoretical condition for status quo and the next several decades with the System Optimizing theory of Multiple Objectives Analysis . The purpose is to provide scientific basis for rational water resources exploitation and utilization, to put forward suggestions for strengthening the management of water resources and to improve local and other Karst Catchment water resources carrying capacrty. Apart from the introduction, this paper can be divided into five parts:...
