【摘要】：基于生态资源环境与社会协调发展的区域城镇化研究已成为我国现阶段地理学研究中的重要科学问题之一。应用熵思想对2010—2012年云南16个市州的支持型输入熵、压力型输出熵、还原代谢型熵和消费代谢型熵、熵流、熵产生及总熵变情况进行定量研究。结果表明:云南省各市州城市社会经济生态系统还处于发展阶段,主要以有序度下降为主;云南省各市州的支持型输入、压力型输出、还原代谢型和消费代谢型4种类型熵存在着显著的空间差异性与单一熵主导性并存现象;云南省各市州城市社会经济生态系统的熵流、熵产生、总熵变存在着显著的空间差异性;云南省各市州城市社会经济生态系统的综合发展得分总体上呈现出东部优于西部、南部优于北部的空间分异格局。
[Abstract]:The study of regional urbanization based on the harmonious development of ecological resources, environment and society has become one of the important scientific problems in geography research in China at present. Based on the entropy theory, this paper quantitatively studies the supporting input entropy, pressure-type output entropy, reductive metabolic entropy, consumption metabolic entropy, entropy flow, entropy generation and total entropy change of 16 cities and prefectures in Yunnan from 2010 to 2012. The results show that the social and economic ecosystem of the cities in Yunnan Province is still in the developing stage, and the order degree is mainly decreased, and the supportive input and pressure-type output of the prefectures in Yunnan Province, The entropy of the four types of reductive metabolism and consumption metabolism exist significant spatial difference and single entropy dominant coexistence phenomenon, the entropy flow and entropy production in the urban social and economic ecosystem of the prefectures of Yunnan Province, Yunnan Province, China, China, China, China, China. There are significant spatial differences in the total entropy change, and the comprehensive development score of the urban social and economic ecosystem in the prefectures of Yunnan Province is generally superior to that of the west, and the southern part is superior to the northern.
