Land use/land cover change responses to ecological water conveyance in the lower reaches of Tarim River, China

The Tarim River is the longest inland river in China and considered as an important to protect oasis economy environment of Basin. However, excessive exploitation over-utilization natural resources, particularly water have triggered a series ecological environmental problems, such reduction volume main river, deterioration quality, drying up downstream rivers, degradation vegetation, land desertification. In this study, use/land cover change (LUCC) responses conveyance lower reaches were investigated using ENVI (Environment for Visualizing Images) GIS (Geographic Information System) data analysis software period 1990–2018. Multi-temporal remote sensing images from 1990 2018 used. results indicate that LUCC covered area 2644.34 km2 during period, accounting 15.79% total study area. From 2018, wetland, farmland, forestland, artificial surfaces increased by 533.42 (216.77%), 446.68 (123.66%), 284.55 (5.67%), 57.51 (217.96%), respectively, whereas areas grassland other types, Gobi, bare soil, deserts, decreased 103.34 (14.31%) 1218.83 (11.75%), respectively. Vegetation first then increased, with order 2010<2000<1990<2018. overflow stagnant was mainly characterized fragmentation, irregularity, complexity. By analyzing 19 rounds 2000 end we proposed guidelines rational development utilization soil resources formulation strategies sustainable River. This provides scientific guidance optimal scheduling region.
