HUANG, Jin; YANG, Wunian; YANG, Xin  and  DENG, Bing. The Influence of Eco-water Retrieved by Quantitative Remote Sensing on Runoff in Upper Minjiang River Basin. Earth Sci. Res. J. [online]. 2016, vol.20, n.3, pp.E1-E6. ISSN 1794-6190.  https://doi.org/10.15446/esrj.v20n2.55177.

Remote sensing quantitative retrieval of ecological water (eco-water) has been foundational in systemic and quantitative research for water resources. Eco-water resource levels indicate conservation ability for the eco-water layer and influence of this on precipitation transformation and runoff regulation. The remote sensing quantitative inversion retrieved the MEC (Modulus of eco-water Conservation) of the Upper Minjiang River Basin study area in 1994 and 2001, and combined with climate data between 1990 and 2005, the influence of conservation water on the eco-water layer on runoff was then analyzed. Results revealed significant efficacy for flood control and water supply during the drought from the hydrologic cycle of eco-water. Thus protection and restoration of the eco-water layer for flood and drought prevention are crucial.
