云南少数民族地区生态环境脆弱,社会经济发展不充分.对其人地系统发展演化过程的研究可为破解环境保护与社会经济发展之间的矛盾,促进区域高质量发展提供科学指导依据.本文基于对人地系统结构的划分,运用数据包络分析方法(DEA)建立综合评价模型,从人地系统协调发展的最终结果——协调发展度,及实现过程——系统综合效率两方面分析云南少数民族地区人地系统演化特征及影响因素.研究结果表明:(1)1995年至2020年,云南少数民族地区人地系统协调发展度总体呈上升趋势,平均值由 1995 年的 0.31 上升到 2020 年的 0.74.(2)各地区人地系统投入与产出平均综合效率值呈下降趋势,尤其2007年后,呈DEA无效的地区逐渐增多,表明高投入、高消耗的发展模式依然没有得到有效改善.(3)工业固体废物综合利用率、对外贸易总额、城镇化率对云南少数民族地区人地系统协调发展效率影响较大.
Evolution Characteristics and Influencing Factors of the Human-Earth System in Minority Areas of Yunnan,China
In minority areas of Yunnan,China,the ecological environment is fragile,and social and economic de-velopment is not sufficient.The research on the evolution of human-earth systems can provide scientific guidance for solving the contradiction between environmental protection and social and economic development and pro-moting high-quality regional development.In this study,based on the structural division of the human-earth system,we established a comprehensive evaluation model by the data envelopment analysis(DEA)to analyze the evolu-tion characteristics and influencing factors of the man-earth system in minority areas of Yunnan in terms of the co-ordinated development degree and the comprehensive efficiency of the system.The results show that:(1)From 1995 to 2020,the coordinated development degree of the human-earth system in minority areas of Yunnan showed an overall upward trend,with the average value rising from 0.31 in 1995 to 0.74 in 2020.(2)The average com-prehensive efficiency of inputs and outputs of the human-earth system showed a downward trend;in particular,af-ter 2007,the number of regions with ineffective DEA gradually increased,indicating that the development model of high inputs and consumption has not been effectively changed.(3)By calculating the system indicator weights us-ing the entropy method,we found that the comprehensive utilization rate of industrial solid waste,total foreign trade and urbanization rate greatly impacted the coordinated development efficiency of the human-earth system in mi-nority areas of Yunnan.
