Remote Sensing Evaluation of Ecological Environment in Chengdu City Based on RSEI Model
Urban ecological environment is an important indicator for evaluating regional development,and remote sensing technology can provide an efficient monitoring tool.In this paper,based on the Remote Sens-ing Ecological Index(RSEI)model in Chengdu city,the quality of urban ecological environment is monitored and evaluated by Google Earth Engine(GEE)cloud computing platform.The article adopts a remote sensing ecological index applicable to the basin plain region,combining greenness index(NDVI),heat index(LST),humidity index(WET)and dryness index(NDBSI)to assess the ecological environment quality level of the region.The results show that the method can carry out urban ecological environment monitoring quickly and efficiently,filling the shortage of monitoring based only on limited ground-based environmental sites,and con-tributing to the high-quality construction of urban ecological environment and sustainable development of the region.
