Analysis of Ecological Flow Based on the Entropy Theory
According to the ecosystem requirement of hydrology conditions in different phase and the daily flow data in Yichang gauge station nearly fifty years,the hydrology indices model is established by using entropy weight and ecological optimal theory.And then the influence of flow,time,frequency and change rate on river ecological flow are analyzed.The results show that the proposed method is feasible.
Purpose ::: Shifts of microbial biomass and functional diversity under different vegetation patterns can impact the soil processes, and the specific knowledge about this can be used to develop sound vegetation restoration strategies. This study was devoted to examine the effects of different vegetation patterns on microbial biomass and functional diversity and explore the relationship between soil erosion and soil microbial properties under typical erosion conditions of the semiarid hilly area of the Loess Plateau, China.
