基于遥感的城市生态环境质量动态变化定量评价——以江苏省宜兴市为例
Quantitative Assess the Dynamic Change of Urban Ecological Environment Based on Remote Sensing——A Case Study in Yixing City, Jiangsu Province
摘要
Abstract
It is important to monitoring urban ecological environment quality comprehensively,rapidly,accurately and quantitatively because the increasing contradiction between the urbanization and human survival environment.Therefore,this article retrieved net primary productivity,vegetation fraction,land surface temperature of urban ecosystem based on remote sensing technology,and for the first time proposed bareness fraction which calculated from normalized difference impervious index,then an ecological environment model was established by integrated these parameters.We applied the model to quantitative assess dynamic change of urban ecological environment quality of Yixing city,the results shows that the ecological environment quality decreasing and increasing areas occupied 79％ and 21％ of total land areas respectively,the significantly decrease areas are 20.56 km2 and not significantly improve areas are monitored.The model has promising application potential because integrated multiple remote sensing parameters,and can rapidly,accurately and quantitatively monitoring the quality change of urban ecological environment.关键词
