摘要: 国土空间是人类生产、生活活动及生态文明建设的载体,如何促进国土空间有序、适度和可持续开发利用,是当前亟待解决的科学问题。基于“三生功能”视角,通过熵权法和功能评价分析长江上游城市群国土空间特征,并利用空间功能比较优势指数、系统聚类等方法,探讨其国土空间优化方案。结果表明:(1)长江上游城市群“三生功能”呈“少强多弱”的特征,空间上城市生产、生活功能测度值自核心城市区向外围区域呈递减的趋势,且低值区总体成片分布;(2)生态功能测度值自核心城市向外围区域总体呈递增的趋势,区域生态安全格局构建与经济发展矛盾明显;(3)将长江上游城市群国土空间划分为4种优势功能区,并提出了长江上游城市群国土空间优化方案。

Abstract: Land space is the carrier of human production, living activities and ecological civilization construction,however,how to promote the orderly, moderate and sustainable development and utilization of land space that is a scientific problem needs to be solved urgently.This paper based on the perspective of “Production Living Ecological”,which using entropy weight method and function evaluation analyzes the spatial characteristics of urban agglomerations in the upper reaches of the Yangtze river,and using the spatial function comparative advantage index, system clustering methods exploring its land space characteristics and optimization plan.The result are as follows:(1)The “ProductionLivingEcological”of the urban agglomerations is characterized by “less strong and weaker”in the upper reaches of the Yangtze River,the urban function measurement value in space shows not only decreasing trend from the core urban area to the peripheral area,but also lowvalue area overall distribution;(2)The ecological function measurement value is increasing from the core city to the peripheral area,and the contradiction between the construction of regional ecological security pattern and economic development is obvious;(3)Dividing the land space of the upper reaches of the Yangtze River into four dominant functional areas and proposed its the optimization plan.
