Coupling of Ecological Economic System in Tarim River Watershed

Abstract

Coupling refers to the objective characterization of the mutual stress and interdependence relations between systems and between elements within the systems. It depicts the evolution or trend of the regional ecological economic system in a certain period of time. The development of a regional ecological economic system mainly depends on the regional comprehensive ecological environmental supporting capacity, regional socio-economic development, and the mutual coordination and coupling between the two aspects. Coupling of the ecological economic system is a spiraling process in which the concept of physics coupling is used to describe the interaction and mutual stress between comprehensive ecological environmental supporting system and regional socio-economic development system to ascend from low-level coordination to high-level coordination. In this paper we will, on top of building an assessment index system, use a quantitative assessment model to demonstrate the coupling of the ecological environment system in Tarim River Watershed and analyze the coordinated coupling and dynamic changes of the ecological environment system so as to provide theoretical reference for sustainable development of the watershed.
