Ecological water conveyance is an effective way to alleviate ecological problems in the form of human intervention to regenerate the degenerated ecology,and it is applied in the surrounding area of the Qingtu Lake,the tail-end lake of the Shiyang River in Minqin County,Gansu Province.The effect of ecological water conveyance on the ecology and environment in the region has attracted much attention.In this paper,the inversion of vegetation coverage (FVC) was reconstructed using the Landsat images in the surrounding area of the Qingtu Lake during the period from 1987 to 2016.The characteristics of the overall dynamic change of FVC were firstly explored,and then the relationship between such change and the ecological water conveyance was analyzed.The results showed that the average vegetation coverage in the surrounding area of the Qingtu Lake was increased from about 10% to 20% in the past 30 years.The change trend of vegetation coverage before and after 2010 was obviously different.The trend analysis was used to compare the characteristics of vegetation cover before and after the ecological water conveyance in September 2010,and the results showed that the effect of climate change on the vegetation coverage in the study area was slight although climate change was the main factor affecting the large-scale vegetation coverage.The vegetation coverage was mainly increased in the area near the lake,and the ecological water conveyance was the main factor affecting its increase.The change of annual vegetation coverage before the ecological water conveyance in 2010 was not obvious,but after that it was in a significant increase trend.
