摘要

[目的]揭示水土流失治理下长汀县农业生态系统和经济系统的耦合规律及演变过程,以期为进一步促进长汀县水土保持高质量发展提供科学依据.[方法]利用1992-2022年长汀县统计年鉴及土地覆盖栅格数据,依据农业生态经济系统演变过程构建了该区域农业生态经济系统的评价指标体系,运用耦合度模型对长汀县农业生态经济耦合系统的演变过程进行了研究.[结果](1)1992-2022年长汀县农业生态系统和农业经济系统综合指数整体上均呈上升趋势;(2)1992-2022年长汀县农业生态经济系统耦合度在10°～270°,系统从衰退耦合过渡到不协调耦合,再到协调耦合、不协调耦合,整个耦合状态演变呈S型曲线;(3)1992-2022年长汀县农业生态经济耦合系统先后经历再生发展、极限发展、协调发展、极限发展的演变阶段.其中 1992-2000年处于再生发展阶段,2001-2002年、2017-2022年处于极限发展阶段,2003-2016年处于协调发展阶段.[结论]根据耦合度发展趋势可以看出,通过优化农业生态和经济措施,系统可以突破不协调耦合朝着协调方向发展,甚至最终进入到良好或优越的协调发展演变阶段.

Abstract

[Objective]The aims of this study are to reveal the coupling pattern and evolution process of agricultural ecosystem and economic system in Changting County under soil erosion control,and to provide scientific basis for further promoting the high-quality development of soil and water conservation in Changting County.[Methods]Based on the statistical yearbook and land cover raster data of Changting County from 1992 to 2022,the evaluation index system of agricultural eco-economic system in this region was constructed according to the evolution process of agricultural eco-economic system,and the coupling model was used to study the evolution process of agricultural eco-economic coupling system in Changting County.[Results](1)From 1992 to 2022,the comprehensive index of agricultural ecosystem and agricultural economic system in Changting County showed an overall upward trend.(2)From 1992 to 2022,the coupling degree of agricultural eco-economic system in Changting County was between 10° and 270°.The system transitioned from recession coupling to uncoordinated coupling,and then to the coordinated coupling and uncoordinated coupling.The whole coupling state evolved into an S-shaped curve.(3)From 1992 to 2022,the agro-ecological economic coupling system of Changting County experienced the evolution stages of regeneration development,limit development,coordinated development and limit development.Among them,1992-2000 was in the stage of regenerative development,2001-2002 and 2017-2022 were in the stage of extreme development,and 2003-2016 was in the stage of coordinated development.[Conclusion]According to the development trend of coupling degree,it can be seen that by optimizing agricultural ecological and economic measures,the system can break through the uncoordinated coupling and develop in a coordinated direction,and even eventually reach a good or superior stage of coordinated development and evolution.
