基于耦合模型的商洛市农业经济与生态环境协调发展研究

Research on the Coordinated Development of Agricultural Economy and Ecological Environment in Shangluo City Based on Coupling Model

为了提升农业经济与生态环境的协调发展水平,对农业经济选取9个指标,对生态环境选取5个指标,构建了农业经济与生态环境两系统的综合评价指标体系,采用综合评价指数模型和耦合协调度模型,对2010~2019年商洛市农业经济与生态环境的发展水平、耦合度、耦合协调度进行了分析。结果表明,2010~2019年,商洛市农业经济和生态环境综合评价值均呈上升趋势,其中,农业经济先呈稳步上升趋势,后期有所波动,生态环境整体呈波动上升趋势;两系统的耦合度处于高水平耦合状态,耦合协调度呈波动上升趋势;研究期内,耦合协调类型多在轻度失调衰退类与濒临失调衰退类之间徘徊,仅2017~2018年上升至勉强协调发展类,后又降回濒临失调衰退类,说明目前商洛市农业经济与生态环境协调发展水平较低。基于此,提出培育优势特色产业、完善农业基础设施、健全生态环境保护机制等建议。

In order to improve the coordinated development level of agricultural economy and ecological environment, based on 9 indicators for agricultural economy, based on 5 indicators for ecological environment, the comprehensive evaluation index system of two systems of agricultural economy and ecological environment was constructed, the comprehensive evaluation index model and coupling coordination model were used to analyze the development level, coupling degree and coupling coordination degree of agricultural economy and ecological environment in Shangluo City from 2010 to 2019.The results showed that the comprehensive evaluation values of agricultural economy and ecological environment in Shangluo City was on the rise from 2010 to 2019,Among them, the agricultural economy was on the steadily rise at first and a fluctuating development later, the ecological environment was on the fluctuating rise;the coupling degree of the two systems was at a high level, the coupling coordination degree of the two systems was on the fluctuating rise;the types of coupling coordination were mostly fluctuating between mild dysregulation decline and near dysregulation decline during the study period, it rose to the barely coordinated development only in 2017~2018,and then descend back to near dysregulation decline, it showed that the coordinated development level of agricultural economy and ecological environment in Shangluo City is currently low.Based on this, some suggestions were put forward, such as cultivating advantageous and characteristic industries, improving agricultural infrastructure, and improving ecological environmental protection mechanisms.
