文山州用水结构与产业结构生态位的耦合协调度分析

An Analysis on Coupling Coordination Degree of Ecological Niche Between Water Consumption Structure and Industrial Structure in Wenshan Prefecture

基于文山州2013年-2022年用水资料,选取生态位、生态熵及其耦合协调度等模型,探索文山州用水—产业结构间的生态位及其熵值的变化、耦合协调度的区域差异。结果表明:文山州的农业、工业、生活用水生态位分别呈高、低、中的变化趋势,三种用水生态熵的区域差异显著;文山州的第一、二、三产业生态位分别呈低、中、高的变化趋势,三大产业结构生态熵的区域差异显著;文山州用水—产业结构的耦合协调关系在弱度失调至弱度协调类型间波动变化,其中农业用水与第一产业表现为起伏较小的波动上升关系,工业用水与第二产业及生活用水与第三产业为起伏较大的波动下降关系。

Based on the water use data of Wenshan Prefecture from 2013 to 2022,the ecological niche measurement method and coupling coordination degree model were used to study the changes of the ecological niche,ecological entropy and coupling coordination degree of water use structure and industrial structure in Wenshan Prefecture.The results showed that the agricultural water niche was large and showed an upward trend,while the industrial water niche and domestic water niche were small and showed an upward trend and a downward trend respectively.The regional differences of ecological entropy of agricultural water use,industrial water use and domestic water use were obvious in 8 counties and cities.The coupling coordination degree of water use structure and industrial structure in Wenshan is between weak imbalance and weak coordination,in which agricultural water use and the primary industry show rising relationship with a small fluctuation,industrial water use and the secondary industry and domestic water use and the tertiary industry show a decreasing relationship with large fluctuation.
