China's natural environment and resources are distributed in unbalance. In order to keep the sustainable use of environmental resources and realize the coordinated development of economy, society and environment, China sets some important parts about environmental protection in the Constitution, and a lot of local environmental regulations are made according to the need of local environmental protection...
In this paper the natural environment geology disasters of mountainous area highway are firstly elaborated, and such geological disasters and their origin as collapse, landslide, mud fluid, Karst, flood damage, special soil, earthquakes and so on is analyzed emphatically. At the same time, such environment geological disasters easily caused by people as roadbed of filling and cutting, constructing...
The Pneumatic Energy (Compressed air) shall be generated through the Novel device, by conversion of Renewable energies in the area - Hydro, Tidal, Waves, Wind, Solar & Salt gradient, utilizing atmospheric air as working fluid. The Pneumatic energy shall be then put into air turbines to produce mechanical energy which shall be converted into electrical energy by conventional method using generators...
Coastal zone detection is an important task in sustainable development and environmental protection. For coastline zone monitoring, extraction and analysis of coastline changes are an important task. Detection of coastline changes by satellite images and remote sensing methods became increasingly important over the recent decades. This study extracted mean high tide lines of the Yellow River estuary...
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...
In practice, caused by external environmental factors influence in the process of river water movement, the river hydrology and water quality characteristics show uncertainty to a large extent. Aiming at the periodicity and randomness feature of hydrological processes, a stochastic water quality model of river is established taking hydrological monthly runoff as random variables and considering three...
In China, researches on classification of fundamental types of geomorphologic form emphasize the integrity of geomorphic units and regional landscape units, and such research results have been mostly applied for some large-scale areas according to a large elevation variation normally. However, there is lack of an automatically effective method within these researches, which can be used to delineate...
At present the environment in Yellow River delta region is particularly badly eroded. In view of the situation, use of vegetation for environmental protection is most effective. In order to select suitable tree species, some physiological parameters such as proline content, ratio of bound water and free water, relative conductivity of leaves were applied to this experiment to probe the capability...
Growing switch-grass in a riparian buffer zone can be one of future best management practices in water resource protection. Switch-grass requires no fertilizers and less land and water. It was recently found to be a good source of biomass. In this study, Soil and Water Assessment Tool (SWAT) model was applied to a watershed to examine the effectiveness of buffer zones of switch-grass in reducing pollutants...
Social-economic development history of China was a long struggle process. Flood, drought and locust plague were regarded as the three biggest natural disasters in Chinese history. Flood and drought which had a close relationship with climate change have been studied by many researchers for a long time. More work should be done on locust plagues that coupled with other natural disasters and social...
The sustainable use of water resources has become an strategic issue involving economic and social development in China. This article presented the situation and characteristics of Poyang Lake water system in Jiangxi province, analyzed the existing problems in exploitation and utilization of water resources and put forward some countermeasures to water environmental protection in Poyang Lake Water...
Protecting the environment and achieving water security, and taking the road of sustainable development, which is the necessary request for fulfilling the scientific outlook on development fully, and the fundamental guarantee for establishing harmonious society. We should explore a new idea of controlling pollution which can integrate the administrative measures, market forces and public participation...
Problems of land ecological security caused by the unreasonable utilization of land resource have influenced the sustainable development of society and economy. This paper selected areas along the Changjiang River in Anhui Province as study area. It constructed an evaluation index system of land ecological security based on Pressure-State-Response model. Considering the illegibility and uncertainty...
The Poyang Lake Ecological Economic Zone is important in Chinese ecological civilization construction, land development; regional coordinated development and rising Jiangxi. So we must plan scientifically and construct on a high level. We should promote Jiangxi rise by relying on abundant natural resources, rational use of various favorable conditions, adopting effective measures, comprehensive environmental...
The application of construction technology of hydraulic fill with sand in high type road in China had made numerous social and economic benefits, but from some successful examples of using this technology, we can know that most of them have certain limitations and it has not developed completely. In this paper, the research of preparatory work, construction technology, environmental protection, quality...
For understanding the regional response to climate change, we explain the characteristics and change of landscape patterns at Huihe National Nature Reserve, Hulun Buir, Inner Mongolia, China. By the visual interpretation method and three-period TM images, we generated landscape classification information with the support of the Arcmap software platform and in combination with ground investigation...
Various types of pollution source were evaluated in this paper through investigation and analysis in the watershed of Xiquanyan reservoir in recent years. Provide scientific and effective reference and technical support in preventing eutrophication of Xiquanyan reservoir and implementing protection and management decisions by government. Calculation and analysis showed the conclusions: Farmland non-point...
As the environmental problem is emphasized by the whole society increasingly, the needs and demands of the environmental data sharing and service are becoming more and more urgent. In the course of constructing State Environmental Data Center (SEDC): organizing, standardizing and strengthening exchanges of data and information between sections; setting up environmental foundation database of the national...
Based on the data that obtained from Liaoning Province environmental quality statistics and LANDSAT 5 satellite image resolution data, eco-environmental quality of Liaoning coastal highway area was respectively assessed with expert assessment method and support vector machine model. Firstly, five assessment indexes of eco-environmental quality were defined which are organism abundance index,vegetation...
