Impacts of Ecological Restoration on Water Resources in Middle Reaches of Yellow River
[Objective] The impacts of ecological restoration in the middle reaches of Yellow River on water resources were studied in order to provide a scientific basis for the eco-environment protection and high-quality development of the basin.[Methods] Based on the GIMMS NDVI
ET
soil moisture
surface runoff and other hydrology data
the study used trend analysis and double cumulative curve methods to analyze the spatial and temporal characteristics of the evapotranspiration
soil water and surface runoff in the middle reaches of Yellow River
before and after ecological restoration.[Results] From 1982 to 2018
the fractional vegetation cover of the middle reaches of Yellow River increased by 29.72%. As the fractional vegetation cover increased by 1%
the evapotranspiration increased by 3~4 mm. In the ecological restoration area
the decline rate of soil moisture was 0.001 3% per year. The average runoff was decreasing from 1961 to 2018
and human activities represented by ecological restoration played an important role in the decline of runoff.[Conclusion] Due to the climate warming and drying and ecological restoration
there is a serious shortage of water resources in the middle reaches of Yellow River. People should consider water resources comprehensively
reduce human interference
and focus on natural vegetation restoration in the follow-up ecological restoration.
