县域经济与环境协调发展分析方法——以西藏自治区为例

A Method for the Analysis of the County level Coordinated Development of Economy and Environment: A Case Study of the Tibet Autonomous Region

环境与经济发展协调问题是环境保护与经济可持续发展中的重要问题,目前有关环境与经济协调程度的分析多是基于人均经济指标与人居环境指标的对比分析。人均指标反映出了经济与环境协调的潜力与可能性,但不能真实地反映区域,尤其是对自然环境依赖程度较大的农区及牧区经济与环境协调的程度。本文在经济与环境协调分析中,加入了反映环境变化的因子,提出了经济与环境协调度概念模型;并利用国土空间开发综合评价指数和归一化植被指数多年变化线性斜率值对指标进行了量化,分析了西藏自治区县域经济与环境协调发展情况,区分了协调县区和不协调县区,从经济与环境协调的角度探讨了各区经济发展的方向。该研究为分析区域经济与环境协调程度提供了新的思路。

The coordination degree of economic development and environmental health （CDEE） is an important issue in the environmental protection and economic sustainable development. CDEE is usually evaluated by comparing the per capita economic index and environmental index. This evaluation method is satisfactory when applied for evaluating the urban CDEE, but it is not suitable to evaluate the rural CDEE, because the economic development is more depend on the environment in rural than that in urban. In fact, the average index reflected is not the actual CDEE, but the potential or possibility of CDEE. A coordination conception model was put forward is this paper, and an index to reflect environmental changes was applied. The CDEE was regarded as a complex of environmental background, economic base, environmental changes and economic development, and its significant representation was environmental changes due to economic development. The CDEE was divided into four levels： uncoordinated, moderate uncoordinated, moderate coordinated, and coordinated. Integrated evaluation index of spatial difference of land development and the annual change linear slope of normalized difference of vegetative index were used to quantify the model index. The CDEE of each county was analyzed in the Tibet Autonomous Region, and the coordinated counties and uncoordinated counties were distinguished.The result reflected the regional differentiation characteristics in environmental protection and economic development in Tibet Autonomous Region more actually. The CDEE is a complicated theme; furthermore, the reasons and patterns of environmental changes both are multifaceted. Thought NDVI reflects environmental change in vegetation coverage, it can not reflect the environmental changes completely. Therefore, it is still necessary to explore other indexes to reflect the environmental changes more actually in CDEE study.
