Abstract

The ecological vulnerability of the Puzhehei karst wetland in 2006-2015 was analyzed based on the comprehensive analysis method of ecological analysis and ecological vulnerability,and the combination of the Remote Sensing and Geographic Information System technology.The spatial-temporal evolution and mutation of the vulnerability were further evaluated.The comprehensive index of ecological vulnerability in Puzhehei karst wetland decreased in 2006-2015,and the level of the ecological fragility was medium.In addition,during this period of time,the spatial and temporal distribution pattern of the ecological vulnerability in the Puzhehei river basin was scattered and the extremely fragile area was shifted from the lower reaches in the Puzhehei basin to the upper reaches.What's more,the area of extremely fragile areas decreased and the trend of deterioration of ecological vulnerability was eased.The entropy of ecological vulnerability had mutations in 2006-2015.The ranking results of the mutation eigenvalue was:stage 2(2009-2012)>stage 1(2006-2008)>stage 3(2012-2015).The results revealed the reason why ecological fragility in the study area changed was the superposition of natural factors and human factors.However,the main driving factors which affected the ecological fragility were the land use,landscape pattern,pollution evolution,and economic development etc.

Key words： ecological vulnerability; spatial-temporal evolution; mutation; entropy; karst wetland
