摘要
采用综合评价指数模型、耦合协调度模型和障碍度模型,对2014~2023年汉中市农业产业结构与农业自然资源生态系统的协调发展水平和障碍因子进行分析。结果表明,研究期内,汉中市农业产业结构与农业自然资源生态系统综合评价值总体呈波动上升趋势,两系统的耦合度整体较高,除2020~2022年为完全耦合外,其余均处于高水平耦合状态;两系统的耦合协调度总体呈上升趋势,耦合协调等级从勉强协调发展类逐步上升至良好协调发展类。农林牧渔业用电量、农村居民人均可支配收入、农林牧渔业总产值比重是影响农业产业结构优化的主要障碍因子;农用塑料薄膜使用量、人均粮食产量、农业用水量、总灌溉面积是影响农业自然资源生态系统改善的主要障碍因子。鉴于此,提出了大力发展现代农业、稳定粮食面积产量、严控农业面源污染、完善农业水利供电设施等促进两系统协调发展的对策建议。
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^(2)014 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^(2)020 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 coupling 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 fishery,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 resources ecosystem.In view of this,some countermeasures and suggestions were put forward to vigorously develop 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.
