区域国土开发强度与资源环境承载力时空耦合关系研究——以沈阳经济区为例

研究目的:揭示国土开发强度和资源环境承载力互动演化的规律,分析沈阳经济区8个城市国土开发强度与资源环境承载力的耦合协调关系。研究方法:利用耦合协调模型分析评判国土开发强度与资源环境承载力之间协调发展及交互耦合的程度。研究结果:(1)2010年以来沈阳经济区各城市国土开发强度不断增长,资源承载力呈现降低的趋势,但环境承载力和社会经济支撑力呈现增加态势;(2)各市国土开发强度与资源环境承载力之间的耦合协调程度较高,达到良性共振,并且协调度呈总体上升趋势,耦合关系日趋紧密。研究结论:国土开发强度与资源环境承载力之间并不存在必然的对立和制约关系,应因势利导,实现两者之间的协调发展。

Spatial-Temporal Coupling Relationship between Land Development Intensity and Carrying Capacity of Regional Resources and Environment: A Case Study in Shenyang Economic Region

The purpose of this study is to reveal the law of interaction evolution between land development intensity and carrying capacity of resources and environment, and to analyze the coupling and coordination relationship between land development intensity and carrying capacity of resources and environment of 8 cities in Shenyang Economic Region. The coupling coordination model is used to analyze the coupling relationship between land development intensity and carrying capacity of regional resources and environment. The results shows that: 1)since 2010, the land development intensity of all cities in Shenyang Economic Region has been increasing, the carrying capacity of resources has been decreasing, while the carrying capacity of environment and social economic support have been increasing. 2)The coupling relationship between land development intensity and carrying capacity of resources and environment is significant, and it will increasingly get close. In conclusion, there is no inevitable contradiction and restriction between the intensity of land development and the carrying capacity of resources and environment. We should make the best of the situation and realize the coordinated development between them.
