摘要
基于生态支撑力模型、组合客观赋权法、GM(1,1)模型、障碍度模型对2010年、2016年、2020年三江源国家公园生态安全水平进行评价、预测与障碍因子诊断。结果表明:三江源国家公园生态安全水平呈先下降后上升并且预测未来继续上升的状态,生态安全等级的变化为中等—较低—中等;从准则层障碍因子看,生态结构指标的障碍度呈上升趋势;从指标层障碍因子看,目前主要的障碍因子为生物丰度指数(C6)、植被覆盖率(C5)、土壤侵蚀度(C11)。
Based on the ecological support model,combined objective weighting method,GM(1,1)model and obstacle degree model,the ecological security level of Sanjiangyuan National Park in 2010,2016 and 2020 was evaluated,predicted and the obstacle factors were diagnosed.The results show that the ecological security level of Sanjiangyuan National Park decreases first and then rises,and predicts that it would continue to rise in the future.The change of ecological security level is medium low medium;From the point of view of the obstacle factors of the criterion level,the obstacle degree of the ecological structure index shows an upward trend;From the perspective of obstacle factors in the indicator layer,the main obstacle factors are biological abundance index(C6),vegetation coverage(C5)and soil erosion(C11).
