In the paper, some relative research theory and calculation methods for the river ecological basic flow both at home and abroad have been summed up, and then, considering the actual conditions of Sushui River, the function of the river reach is determined. The ecological basic flow of the river in different periods has been quantitatively researched with Tennant and the minimum monthly average flow...
In recent years, researchers pay increasingly attention on river ecological restoration at home and abroad. According to the practical situation of Tianjin Airport Economic Park river water environment and inter-external experiences, several ecological techniques, such as phytoremediation, artificial aeration and ecological riverbank, were adopted to river ecological restoration. And related operation...
Currently, urbanization has entered a stage of rapid growth in China, the environmental pollution and ecological destroy of cities are becoming more and more serious day by day. The work field of city planning and design is beginning to expand to undertake a task to improve living and ecological environment due to paying more attention to afforesting and ecological construction. Under the new background...
Since 1997, Costanza and others assessed the value of global ecosystem services. The assessment methodology and the adaptability of the established methods have become the concern of academia. The paper assesses the four forest ecosystem services of Beibu Gulf in China, based on the services valuation methods, accepted by civil experts. These services include forest products, carbon sequestration...
According to climate, vegetation, geomorphology, the degree of the Kaschin-Beck disease and geology, hydrogeology, soil, the degree of original environmental transform as well as the difference of the disease, etc., the authors divided the east of Jilin province into three ecological environmental zones (A,B,C), compares the situation among three zones, then draws conclusions as follows: Kaschin-Beck...
Wetlands which have been called the "kidneys of nature", with ecological, economic and social benefits are related to the national ecological security. State wetland management has gone through the management with the purpose of wetland resources use and the wetland ecosystem management stage for maintaining the health of wetland ecosystem. On the basis of analyzing the development and utilization...
The Three Gorges Reservoir is one of the largest water conservancy and control projects in the world. After the accomplishment of the project in 2009, a 30-meter high water-level-fluctuating zone will appear along the banks. The WLFZ is a seasonal humid ecosystem . The distributed features and useful values of WLFZ are explored according to the program of water storage in the Three Gorges Reservoir...
A risk assessment for water shortage is constructed to analyze the carrying capacity of water resources in Sheshui River watershed, China. It is based on the information of present economic development. There are several serious environmental problems which might cripple the development potential in Sheshui River watershed. Risk assessment results are used to analyze the carrying capacity of water...
A centralized wastewater treatment system has always been regarded as a successful approach during the last century. However, the transfer of this highly water-, energy- and cost-consuming system, and "end-of-pipe" technology to developing countries like China has been proved to be extremely limited and not always feasible. Decentralized water management based on ecological sanitation (EcoSan)...
Capital Economic Circle that is located in north of China belongs to water resources shortage regions. The per capita water of it is only 1/7 of the per capita water of the whole country, and 1/30 of the per capita water of the whole world. Thus water resources problems become one of the key factors that restrict regional development. According to the analysis of water resources situation in Capital...
Eco-water (layer) refers to the water body closely related to the ground vegetation layer. It is conserved in leaves, roots, vegetation humus layers and root soil layers, which is capable of precipitation interception and rivers and/or groundwater supplementation. As a challenging issue in the hydrological cycle field, the eco-water and its resource quantity are difficult to be quantified by ordinary...
