摘要
探究喀斯特地区农业生态经济系统的耦合协调关系与演变趋势,对科学评价该地区生态治理效益与实现农业生态经济协调发展具有重要意义。以典型喀斯特生态脆弱区贵州省为例,基于农业生态环境与农业经济发展数据,构建农业生态系统与农业经济系统的评价指标体系,采用熵权法、耦合协调度模型与耦合度模型定量分析了二者的综合评价指数、耦合协调状态与耦合度演变趋势。结果表明:2000~2019年,贵州省农业生态系统综合评价指数呈现先降后升的变化趋势,农业经济系统综合评价指数则保持稳步上升态势,二者之间由“经济滞后型”逐步演变为“生态滞后型”。农业生态经济系统耦合协调度指数整体呈上升趋势,从0.2680增长至0.6606,耦合协调状态由中度失调水平演变为初级协调水平。耦合度呈现由大到小的变化趋势,系统经历了从耗损发展向协调发展的转变,说明贵州省农业生态经济系统显现出趋向协调的发展态势。研究表明,贵州省应继续践行生态优先、绿色发展理念,优化生态环境与经济发展的关系,实现农业生态经济系统的高水平协调发展。
It is of great significance to explore the coupling coordination relationship and evolution trend of the agricultural eco-economic system for scientific evaluation of ecological governance benefits and realization coordinated development of agricultural eco-economy in the karst area. Taking Guizhou Province as an example, based on the data of agricultural ecological environment and agricultural economic development, this paper constructs the evaluation index system of agro-ecological system and agro-economic system. Using entropy weight method, coupling coordination degree model and coupling degree model, we quantitatively analyzed the comprehensive evaluation index, state of coupling coordination, and trend of coupling degree evolution of the agro-ecological system and agro-economic system in Guizhou Province from 2000 to 2019. The results showed that the comprehensive evaluation index of agro-ecological system presents a trend of first decreasing and then increasing in Guizhou Province, but the agro-economic system maintains a steady rising trend, and the relationship between the two is gradually evolving from “economic lag type” to “ecological lag type”. The coupling coordination index of agricultural eco-economic system increased from 0.268 0 to 0.660 6, besides the coupling coordination state developed from the moderate imbalance level to the primary coordination level. The coupling degree presents a trend from large to small, and the system has experienced a change from depletion development to coordinated development, which indicates the agricultural eco-economic system of Guizhou Province showing a trend of coordinated development. Our results indicate that Guizhou Province should continue to practice the concept of ecological priority and green development, optimize the relationship between ecological environment and economic development and realize the high-level coordinated development of agricultural eco-economic system.
