Changes of Lake Area, Groundwater Level and Vegetation under the Influence of Ecological Water Conveyance—A Case Study of the Tail Lake of Tarim River in China

To study the changes of water and vegetation coverage, groundwater level plant diversity lakes at end Tarim River in Northwest China, various indicators more than 20 years (2000–2019) were analyzed through field investigation indoor remote sensing methods. The results showed that (1): with initiation development ecological conveyance project, areas increased significantly, especially trend becoming significant, area sandy land decreased significantly. (2): early stage conveyance, however, increase lake level, species composition tends to be simplified. According variation characteristics importance value overflow recent years, it is found top communities succession are Phragmites australis Hexinia polydichotoma. (3): area, an up-lifted trend, correlation between two was but there a lag response level. (4): intra-annual variations considerable before after conveyance.
