Setting up a reasonable ecological value evaluation system for residential quarters is important to improve people's living level. An evaluating index system with contains 2 factors, 12 sub-factors, and 50 elements is established. Then we use FAHP in determining the weights of the factors and sub-factors, which can reflect the human thinking style. At last, we establish a multi-grade fuzzy synthetical...
Ecological system, especially wetland is suffering form gradually degeneration in recent years, but due to the long length of classification standard span, the current wetland ecological water demand and ecological water level could not reflect the actual continuity characteristics of ecosystem changes. Therefore, it is possible to evaluate wetland ecosystem health condition and establish relationship...
The Shiyang river is one of the most serious basins confronting the severe water scarcity and eco-environmental issues in the Hexi Corridor of Gansu province, northwestern China recently, which is of particular importance for regional economic and social development.

A multi-species prairie composed primarily of clonal plants can achieve different ecological functions. They can be a good source of biofuel, a mean of water purification in agriculture or a biodiversity guardian. The goal of the virtual prairie project is to study the fundamental mechanisms involved in the population dynamic of a prairie and the optimum engineering design of prairies serving these...
