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...
Submerged aquatic vegetation (SAV) is a potent water-purifying agent enhancing integrity of lake ecosystems. Therefore, mapping the distribution of SAV in lakes is very important for managing the water quality and serves to conservation purposes. Current method for mapping SAV, i.e. collecting plant samples from shore, is not applicable to mapping wide areas. Here we report the novel method for mapping...
Growing population and rapid economic development lead to increasing pollution loading and lowering water quality. Protection of water environments is our glory target; The key strategy is: combining management of the land-water system in catchment and realizing the quasi-non-pollution release in an as small as possible catchment area.”; developing the high technology for realizing this target in...
In view of there's no generally accepted ecological compensation standard and method, it might induct the negotiations in the process of ecological compensation of water source, government in water source and in downstream of the basin according to the respective rights and obligations, and distinctive nature of water characteristics, through negotia- tions to establish their compensation standard,...
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...
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...
The utilization of rainwater is essential to improve ecological environment of sub-district, and is one of main approaches to achieve sustainable water resources.Taking rainwater collection and utilization of Beifang Garden district as an example in Fuxin city of northeast China, water quality analysis and water quantity balance calculations are completed, also the feasibility and necessity of rainwater...
This work addressed the integrated project management of water resources in a costal city, Haihou City in China. Based on investigation of renewable water resources distribution, an underground water storage project was carried out for water safety utility and seawater intrusion prevention in the new planned city area. Methods for surface water reuse and seawater intrusion prevention were integrated...
Study on eco-environmental water requirement was of great significance in the planning and regulation of ecological water system, and the regional optimization of water resources. The river ecological water requirement is the core of the study. In this paper the meaning of eco-environmental water requirement and ecological status of lake are discussed. Based on the environmental flow of natural ecosystem,...
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,...
An integrated rehabilitation program of the urban water environment (UWE), was proposed against deterioration of the UWE in Guilin City, China. Four measures of water conservancy, pollution control, ecological rehabilitation and landscape construction were developed to achieve many objectives including plentiful water, safe supply, steady system and attractive scenery. During the 1st period project,...
