Comprehensive Assessment Models for Regional WaterResources Coordination with Society-economy andEnvironment

摘要

Based on sustainable water resources and complex system theory, A system whichcomposed by water resources, society and economy, environment is defined as a water resourcescomplex system (WRCS). With the Bossel' s orientor indicators framework of sustainable development,the indicators system of WRCS is established and its comprehensive assessment values arecalculated. Also, the authors use synchronization development equation to construct the coordinationmodel of WRCS, which measure the spatial distance between comprehensive assessment value anddesiring assessment value and the coordination extent of WRCS. In order to measure the coordinationextent at high and low level of WRCS, the relative value of development value of society-economy andenvironment subsystem are used to rectify the coordination model, which is the ratio of developmentvalue to desiring development value of society-economy and environment subsystem. Finally, themodels are applied to the assessment of water resources utilization in Guan Zhong, Shaan Bei andShann Nan region of Shaanxi Province. From 1986 to 2000 year' s assessment results, the model isreasonable and practical.
