福建省农业经济系统与生态系统的耦合协调性分析

Analysis on the Coupling Coordinated Development of Agricultural Economy and Ecological System in Fujian Province

对1990—2017年福建省农业经济系统与生态系统的统计数据进行分析,运用熵值法、灰色关联分析法、耦合度模型研究两系统的发展水平、耦合度、协调发展度的演变规律。结果表明:福建省农业经济系统与生态系统的灰色关联度高,耦合作用较强;1990—2017年福建农业生态环境系统与农业经济系统耦合协调度由1990年中度失调到2017年初级协调;农业生态综合评价指数与农业经济系统综合评价指数皆是良性稳步上升的变化趋势;数据预测福建省将于2022年农业生态系统与农业经济系统达到中级协调。建议因地制宜合理利用生态资源,加强农业现代化规模生产,加强农药化肥的使用监督。

Based on the statistical data of agricultural economic system and ecological system in Fujian Province from 1990 to 2017,entropy method,grey relational analysis method and coupling degree model were used to study the evolution law of development level,coupling degree and coordinated development degree of the two systems.The results show that,on the whole,the grey correlation between agricultural economic system and ecological system in Fujian Province is high,and the coupling effect is strong.From 1990 to 2017,the degree of coupling coordination between the agro-ecological environment system and the agro-economic system in Fujian changed from moderate imbalance in 1990 to primary coordination in 2017.The agro-ecological comprehensive evaluation index and agro-economic system comprehensive evaluation index both have a benign and steady rising trend.It is predicted that the agricultural ecosystem and agricultural economic system in Fujian Province will reach the intermediate coordination in 2022.It is suggested to make rational use of ecological resources according to local conditions,strengthen modern large-scale agricultural production,and enhance the supervision of the use of pesticides and fertilizers.
