Develop eco-tourism is the important way of Sustainable development tourism and environmental protection. Liaoning coast economical belt has rich eco-tourism resources. It has provided the important condition for the eco-tourism product development. The article has carried on the quality synthetic evaluation and the analysis to the key eco-tourism resources. In this foundation, proposed the plan that...
As a unique natural region unit and the "buffer zone" which connects reservoirs and its peripheral region, the reservoir shore zone not only provides geographical space and resources-environmental supporting conditions for the local socio-economic development, but also plays a "barrier" role in maintaining reservoir ecosystem services function and protecting the environmental security...
Because all aspects of reasons, some areas in China are subject to different levels of soil pollution, ecological environment, food security and agricultural sustainable development constitutes a threat, soil pollution, the situation is grim. Cleanup (or remediation) technologies available for reducing the harmful effects at heavy metal-contaminated sites include Solidification/Stabilization Technologies,...
Urban wetlands play a significant role in the sustainable development. But the effect of human action on urban wetlands has been expanded in greater scope and depth, which may cause the accelerated degeneration of urban wetlands seriously. Based on the historical data of land using maps, topographic maps and TM images of Wuhan from 1930s to 2005, which were through the Man-Machine Interaction in ArcGIS...
Mangroves are small evergreen trees that flourish in the intertidal zones of river deltas, lagoons, estuaries, and coastal systems in the tropics, subtropics, and some temperate coasts. Mangroves provide a variety of ecological services for human beings, such as the protection of coasts from typhoon damage, pollutant absorption, and water purification. Guangdong province, used to locate half of mangrove...
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...
The quarry and damaged mountain in peri-urban have an important influence to ecological environment. They have had a series of serious environmental-geological problems to the socio-economic development and urban modernization process, such as increased environmental pollution and soil erosion, destruction of landscape aesthetic, induced geological disasters, and had an impact on groundwater seepage...
An environmental impact method based on numerical simulation is proposed and the assessment of environmental impact caused by dam-break is gained. According to the dam-break flood simulation results, the routing process of dam-break flood is concluded. Then the environmental risk evaluation model is built based on the obtained hydraulic factors. Qing Linjing reservoir located in Shenzhen of China...
Urban areas are complex ecosystem of interacting social, economic, and natural components, dominated by human activities. Wetlands are an important part in urban ecosystem as they play an important role in the health and sustainable development of urban ecosystems. This paper discusses the concept of ecological service function in the face of wetland decline, and possible strategies for wetland conservation.
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.
Water is a sort natural resource that can't be replaced. It is also one of the important supports for the sustainable development of society and economy. According to characteristics of urban water resources system, an optimal allocation modal of water resources is built considering coordinative development among multi-objective and regions such as the production, living and ecology. Taking gray theory...
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,...
The ecological footprint of Pinggu District in 2001 and 2005 was calculated and comprehensively analyzed. Results showed that the ecological footprint, ecological carrying capacity and ecological deficit in 2001 were 2.1464 hm2/cap, 0.3344 hm2/cap & 1.81204 hm2/cap respectively, and then 3.6172 hm2/cap, 1.8794 hm2/cap & 1.7378 hm2/cap in 2005. By contrast the results of 2001 with 2005's, it...
Sustainable development is widely practiced by many engineers, academicians and policy makers for making the industries environmental friendly, to obtain sustainability in any industry there are many methods. Resources utilized in an industry should be identified properly in various processes and its utilization is to be optimized to increase the environmental performance of the industry. Ecomapping...
