摘要
通过引入生态支撑力评价体系与模型,从自然生态系统角度对2020年青海省生态支撑力水平进行综合评价。同时借助于障碍度模型对影响青海省生态支撑力水平的各指标进行主要障碍因子诊断。结果表明:2020年,青海省生态支撑力处于较低水平(Ⅳ级),影响其水平的主要障碍因子是景观破碎度(C4)、土壤侵蚀度(C11)。据此,提出与诊断结果相应的对策建议。
In this paper, ecological supporting force evaluation system and model were introduced to comprehensively evaluate the ecological supporting force level of Qinghai Province in 2020 from the perspective of natural ecosystem.At the same time, with the help of the obstacle degree model, the main obstacle factors of each index affecting the ecological support level of Qinghai province were diagnosed.The results show that the level of ecological support in Qinghai province in 2020 is at a low level(Grade Ⅳ),and the main obstacle factors affecting the level are landscape fragmentation degree(C4) and soil erosion degree(C11).Accordingly, the corresponding countermeasures and suggestions are put forward.
