Change and Driving Factor Analysis of Eco-Environment of Typical Lakes in Arid Areas

In arid regions with scarce water resources, lakes play an extremely vital role in maintaining the ecological environment. Therefore, Chinese government has launched conveyance project Tarim River basin Xinjiang aim of restoring environment area. previous studies, there was no complete evaluation system used to quantify changes after conveyance. this paper, Lake Taitema selected as study area, which is both a terminal lake and object project. This utilized Landsat TM/OLI satellite remote sensing images MODIS datasets build index model systematically evaluated land use types A structural equation constructed analyze correlation between area its driving factors. The results show that over 20 years, proportion pixels upward trend (Zc > 0) RSEI 56.5%, while downward < 43.5%. poor quality decreased by about 40%, proportions moderate, good, excellent increased 29.7%, 10%, 0.6%, respectively. By comparing data from 2000 2020, grassland 6%, 4.4%, unused 9.6%. summary, implementation project, gradually improved, main factor change Taitema.
