The compensation standard determination is the most critical and difficult element to identify in the watershed eco-compensation mechanism. There have been many studies to determine compensation principles and methods. In this paper, the assumption of establish the eco-compensation mechanism of two-way responsibility for upstream and downstream based on the primary and advanced compensation has been...
Payment for watersheds services (PWS) is an important instrument of watersheds protection and management, which can transform fortune and reduce the inequity of environment and development between the upper reach and lower reach. Both government and market play a key role in the course. Based on case study of Jinhua River, the analysis on the payment mechanism and modes of environmental services and...
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...
Due to the different ecological characteristics of the cities, the current national standard can not normalize the eco-city construction in China. To solve this problem, this paper puts forward a new method to set up different index systems based on the classification of cities, i.e., represent the generality of the cities by a set of common indices for comparison; classify various cities by a set...
Baiyangdian is the largest wetland in north China, and plays an important role in many aspects such as climate regulation, biodiversity protection, flood control, and local fishery production etc. the research of this paper include the following four aspects: 1) The composition, current situation, and changing tendency of sub-systems that constructed the whole system. 2) Building up the system model...
A water balance model is established in this paper. The relationship between water requirement and lake ecosystem is built and reflected by the appropriate water level to protect lakes and wetlands. And some measures of controlling human management action with water limit are put forward by the example of the Baiyangdian Lake.
The prevalent water problems like quantity shortage, environment pollution and ecological damage restrict urban sustainable development. Unreasonable water utilizing causes conflicts between artificial water cycling system and natural cycling water system, which turns out to be the source of urban water problems. To find ultimate solutions to the water problems and the way of sustainable water utilization,...
