河北坝上内陆湖盆湿地生态脆弱性评价研究

Study on Ecological Frangibility Evaluation of Bashang Inland Lake Wetland in Hebei Province

选取14个表征生态脆弱性的具体指标并赋以权重,通过计算生态脆弱性指数对坝上内陆湖盆湿地生态脆弱性进行了评价。结果表明:坝上湿地整体脆弱性程度为中度接近于强度脆弱,以县为评价单元的脆弱程度状况为尚义>张北>康保>沽源,主要的脆弱性因素是水资源及植被状况。以上结果说明坝上内陆湖盆湿地生态脆弱化现象严重,生态保护和恢复工作不容忽视。

14 concrete indices that indicated ecological frangibility were selected and weighted.Through calculating the ecological frangibility index, the ecological frangibility of Bashang inland lake wetlands was evaluated.The results showed that the Bashang wetland overall frangibility degree was moderate,close to intense frangibility.Taking counties as the evaluation units,the vulnerable degree was ShangyiZhangbeiKangbaoGuyuan.The main vulnerable factors were water resources and vegetation status.The above results showed that fragile ecology of Bashang wetland was a serious problem,and the ecological protection and restoration work should not be ignored.
