汉中市农业产业结构与农业自然资源生态系统耦合协调及障碍因子分析OA

The comprehensive evaluation index model,coupling coordination degree model and obstacle degree model were used to analysis the coordinated development level and obstacle factor of agricultural industrial structure and agricultural natural resources ecosystem in Hanzhong city from 2014 to 2023.The results showed that the comprehensive evaluation values of agricultural industrial structure and agricultural natural resources ecosystem in Hanzhong city were on the fluctuating rise during the study period;the coupling degree of the two systems is generally higher,except for the complete coupling from 2020 to 2022,the rest are in a high-level coupling state;the coupling coordination degree of the two systems was generally on the rise,the level of cou-pling coordination has gradually increased from the category of barely coordinated development to the category of well coordinated development;the electricity consumption of agriculture,forestry,animal husbandry and fish-ery,the per capita disposable income of rural residents,and the proportion of total output value of agriculture,forestry,animal husbandry and fishery are the main obstacle factors that affect the optimization of agricultural industrial structure,the use of agricultural plastic film,per capita grain output,agricultural water consumption,and total irrigated area are the main obstacle factors that affect the improvement of agricultural natural re-sources ecosystem.In view of this,some countermeasures and suggestions were put forward to vigorously devel-op modern agriculture,stabilize grain area output,strictly control agricultural non-point source pollution,and improve agricultural water conservancy and power supply facilities to promote the coordinated development of the two systems.
