摘要
为评价四川省生态健康状况,利用四川省2011~2021年的相关数据,构建基于DPSIR模型的评价指标体系。运用博弈论组合赋权确定综合权重,再使用综合指数法评价健康状况,并进行障碍度分析。结果表明:四川省生态健康综合评价指数整体呈上升趋势,实现了由病态到健康状态的转变,2015年后状态子系统评分较低;人口密度、人均用水量、植被覆盖率、排水管道长度、人均水资源量是主要障碍因子,其中人口密度的障碍度明显高于其他障碍因子;压力子系统障碍度明显减少。
To evaluate the ecological health status of Sichuan Province,an evaluation index system based on the DPSIR model was constructed using relevant data from 2011 to 2021.The comprehensive weights were determined by the game theory combination weighting method,and the health status was evaluated using the comprehensive index method,followed by an obstacle degree analysis.The results show that:①The comprehensive evaluation index of ecological health in Sichuan Province has generally shown an upward trend,achieving a transformation from a pathological state to a healthy state.However,the score of the state subsystem has been relatively low since 2015.②Population density,per capita water consumption,vegetation coverage rate,length of drainage pipes,and per capita water resources are the main obstacle factors,among which the obstacle degree of population density is significantly higher than that of other obstacle factors.The obstacle degree of the pressure subsystem has decreased significantly.
