摘要/Abstract

摘要： 治沟造地是继退耕还林工程后延安市实施的又一项重大生态环境治理工程。研究治沟造地工程背景下延安市农业生态经济系统耦合关系的发展变化,对科学评价治沟造地工程生态经济效益和黄土高原地区农业生态经济协调与可持续发展具有重要意义。本研究通过构建农业生态经济系统耦合协调度模型和耦合度模型,定量分析了2010—2018年延安市农业生态与农业经济系统的综合评价指数变化、耦合协调状态及耦合度演变趋势。结果表明: 2010—2018年间,延安市农业生态系统综合评价指数和农业经济系统综合评价指数均呈现S型增长曲线,两者变化趋势较为一致;农业生态经济系统耦合协调度指数由0.51增长至0.72,耦合协调状态由初级协调水平发展为良好协调水平,说明该区域农业生态与经济关系不断改善,系统耦合关系向相互协调的方向发展;研究期间,延安市农业生态经济系统耦合演变过程较为复杂,系统耦合趋势经历了“衰退耦合、协调耦合、修复耦合、协调耦合”阶段,2018年耦合关系处于经济快速增长的协调发展阶段。治沟造地工程促进了农业生态经济系统的耦合协调发展,但其生态经济效益具有一定的滞后性。

Abstract: The gully control and land consolidation project is another major project of ecological environment management in Yan’an City following the Grain-for-Green project. Understanding the development and changes of the coupling relationship within agricultural eco-economic system in Yan’an City under the background of gully control and land consolidation project has important implications for scientific evaluation of ecological and economic benefits of the project as well as the coordination and sustainable development of agricultural eco-economy in the Loess Plateau. By constructing the coupling coordination degree model and coupling degree model of agricultural eco-economy system, we quantitatively analyzed the change of comprehensive evaluation index, state of coupling coordination, and trend of coupling degree evolution of the agricultural eco-economic system in Yan’an City from 2010 to 2018. The results showed that the comprehensive evaluation index of agricultural ecology and agricultural economy systems in Yan’an City from 2010 to 2018 both followed an S-shaped growth curve, with consistent trend. The coupling coordination index of the agricultural eco-economic system increased from 0.51 to 0.72, while the coupling coordination state developed from the primary coordination level to a good coordination level. Such a result indicated continuous improvement of the relationship between agricultural ecology and economy in the region and the coupling relationship of the system were developing with the direction of mutual coordination. During the study period, the agricultural eco-economic system coupling evolution was complicated and experienced different stages, including decline coupling, coordination coupling, repair coupling, and coordination coupling again. The coupling relationship was at the stage of coordinated development of rapid economic growth in 2018. The gully control and land consolidation project promoted the coupled and coordinated development of agricultural eco-economic system, but with a lagging effect.
