摘要

[目的] 探究黄土丘陵沟壑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经济效益、实现农业生态经济协调与可持续发展具有重要意义。[方法] 以陕西省吴起县为研究对象，基于农业生态与农业经济数据，构建农业生态经济系统评价指标体系，运用熵权法、耦合协调度模型和耦合度模型分析了农业生态与农业经济的综合评价指数、耦合协调状态及耦合度演变趋势。[结果] 1990—2019年，吴起县农业生态综合评价指数呈现先下降后上升的发展趋势，农业经济综合评价指数经历较快速上升—稳定发展—快速上升的发展过程；耦合协调度指数由0.29上升至0.63，反映了该地区农业生态与农业经济的协调发展不断增强，耦合协调状态由轻度失调演变为初级协调水平；耦合度表现为先下降后上升趋势，系统由耗损发展阶段过渡到协调发展阶段，说明吴起县农业生态经济系统不断趋于协调发展的态势。[结论] 在丘陵沟壑区，我们应该继续以生态保护为基础，优化产业结构，调整生态与经济的发展关系，更好地实现农业生态环境与农业经济的协调发展。

Abstract

[Objective] The coupling coordination relationship and evolution trend of the agricultural eco-economic system in the loess hilly and gully regions was determined

in order to provide a basis for scientifically evaluating the ecological economic benefits of the region

and for realizing the coordination and sustainable development of agricultural eco-economics.[Methods] Based on agro-ecology and agro-economy data from Wuqi County

Shaanxi Province

an evaluation index system for the agro-ecology and agro-economy system was constructed. The comprehensive evaluation index

coupling coordination state

and coupling degree evolution trends for the agro-ecology and agro-economy systems were analyzed by using the entropy weight method

coupling coordination degree model

and coupling degree model.[Results] From 1990 to 2019

the comprehensive evaluation index of agricultural ecology at Wuqi County initially decreased and then increased. The comprehensive evaluation index of the agricultural economy followed the pattern of relatively rapid rise-stable development-rapid rise. The coupling coordination index increased from 0.29 to 0.63. This increase reflected the coordinated development of agricultural ecology and the agricultural economy in the region that has continuously strengthened over time

and the state of coupling coordination that has evolved from a slight imbalance to a primary level of coordination. The degree of coupling showed a downward trend followed by an upward trend

and the system has transitioned from a depletion development stage to coordinated development

indicating that the agricultural eco-economic system at Wuqi County was constantly developing in a coordinated manner.[Conclusion] We should continue to optimize the industrial structure based on ecological protection and adjust the relationship between ecological and economic development to better coordinate the development of the agricultural ecological environment and the agricultural economy in loess hilly and gully area.
