Assessment And Optimization On Sustainable Development Of Forest Resources-Environment-Economy Composite System (FEES)

Nowadays, environment and development are two subjects of the society. Sustainable development as a latest development idea and development mode is the objective of twenty-first century, as well as is approved by all the people in the world and has attracted all the eyes of international society. Due to forest resources are the material basis of the global ecological environment, it is commonly known that forest resources sustainable management benefits and safeguards the society sustainable development. This paper studied the composite system among forest resources, environment and economy, which will help to fulfill the regional sustainable development. The main results of the research are as follows:Firstly, based on the synthetic analyses of the theories of sustainable development, forest resources sustainable management, FEES sustainable development at home and abroad, the intention and principles of sustainable development were presented.Secondly, depending on systematic analyzing the natures of the subsystems of forest resources, environment and economy, the essential feature, general structure and internal mechanism, the relationships of subsystems on FEES sustainable development were studied, as well as its content. The objective system of the composite system was given.Furthermore, the basic principles, assessment essentials and quantitative indicators of the comprehensive assessment of composite system were established. This assessment method was applied to Jiangsu province by means of modified Analytic Hierarchy Process (AHP) based on fuzzy consistent matrix considering the limitations of AHP. Some referential conclusions were drawn that the subsystems of forest resources and environment lie in weak sustainable development state expect the economy subsystem stands in a below-medium sustainable development, and the coordination development degree of the three subsystems is obviously low. So the countermeasures were proposed for Jiangsu province.In the last of this paper, according to the general structure and sustainable development targets of FEES, a multi-objective integrated model was formed and complex system optimization model for Jiangsu's coordination development of forest resources, environment and economy was formulated, Which could provide technical tool for the quantitative study on regional sustainable development. By this model, optimization values of sustainable development of Jiangsu's FEES in 2010 were obtained, and some strategies were proposed.
