摘　　要：城市化与人类生存环境改善之间的矛盾日益突出,综合、快速、准确、定量监测城市生态环境质量状况尤为重要.以利用遥感技术反演城市生态系统净初级生产力、植被覆盖度和地表温度等生态参数,提出基于归一化不透水指数的地表裸露度;综合以上参数建立基于遥感参数的生态环境指数模型,并运用该模型定量评价江苏省宜兴市生态环境质量动态变化.结果表明,2000—2013年,宜兴市生态环境质量呈下降和升高趋势的面积分别占总面积的79%和21%,其中,20.56km2呈显著降低趋势,并未监测到显著改善区域.该模型综合各项遥感参数,能快速、准确、定量监测城市生态环境质量变化,具有良好的应用潜力.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 20.56km2 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.
