To monitor the land sandy desertification dynamic change accurately in Duolun, the desertification was classified and evaluated based on the land use point of view and the evaluation index system based on land use was set up. TM image was decomposed by linear spectral mixture mode and the vegetation component of TM image was amended by the high-resolution satellite image to extract the information...
Bosten Lake, which locates in arid and desert zone, is the largest lake in Xinjiang, and is the largest inland freshwater lake in China. It has giant value in environment, ecology and economy. The water level of Bosten Lake has taken place tremendously in the recent 50 years, the water level descended from 1048m above sea level in 1958 to that of 1045m in 1987, and ascended from 1045m to 1048.9m during...
Sampling method was employed to investigate the structure and ecological benefits of street trees in the area within Second Ring Road of Shenyang. The study area covers about 161 km2, and 61 main roads. Based on the field data, the i-Tree (STRATUM) model was run to analyze street trees' structure and ecological benefits. The results showed that there were 19 street tree species in the study area,...
This paper reveals the relation between ecotourism and ecological civilization as well as that between visitor environmental education and ecotourism, analyses the specific roles that visitor environmental education plays, points out the present questions and their harm in the existing visitor environmental education in ecotourism in mainland China. In order to make visitor environmental education...
In this paper, the measured date of air environment quality, water environment quality, acoustic environment quality and solid wastes in the Kanas National Natural Heritage Site of China during different periods were compared, the main factors resulting in the tourist environment pollution were evaluated, and corresponding ecological design approach for controlling tourist environment pollution was...
Kangding County is the important gateway to Tibet Autonomous Region, China. Recently, Kangding County, relying on its water, minerals, tourism, ecology and other advantages of resources, has developed economy, which impact on the ecological environment more apparently. In this paper, we used two LANDSAT TM and ETM data sets and some other vetor data to quantitatively estimate changes in the size of...
Oasis cities are the special regions in arid zones, which have the densest human activities and the most sensitive relationship between human and natural environment. Rapid urbanization of oasis cities of Xinjiang, China has impacted on the stability and economic sustainable development of the region during the past decade. Therefore, monitoring urban spatial growth and land cover change brought on...
This paper aims to address a case study of strategic environmental assessment (SEA) on the planning of ChangPing region in Beijing China. And puts forward the enforcement framework and a basic procedure of regional Plan EIA for urban regional sustainable development. The new methods with the ecological suitability analysis of regional development and environmental carrying capacity as its core are...
Ten sites along the XiJiang River (WuZhou section), China were sampled to evaluate the copper (Cu), Zinc (Zn), lead (Pb), cadmium (Cd), and chromium (Cr) concentrations in sediments. The order of total metal concentrations in sediment samples was found to be Zn>Cu>Cr>Pb>Cd. The approach of Hakanson potential ecological risk index was used for the ecological risk assessment. Compared to...
Due to the perfect management of hospital information system, the hospital staff could draw a better heal scheme for patients with the whole information when they take care of them. And hospital information in the medical environment has also played a key to the role to make patient have a convenient and efficient medical environment. These are the strong protection for the hospital flinty competition...
Net primary productivity (NPP) estimation is an important study field of global change and terrestrial ecosystem. Here, we present an integrated modeling and analysis framework for researching climate change using NPP as an ecosystem indicator. It's brings together remote sensing, GIS and an ecosystem simulation model without requiring users to have any knowledge of any other specific software. Satellite...
Pond is an ideal study target which can be regarded as an enclosed ecosystem with little external disturbance such as pollution discharge. The aim of the study is to obtain further understandings of freshwater eutrophication mechanism through a one-year's intensive observation and monitoring program for a shallow pond in Chongming Island, China. The result showed that NO3-N, PO4-P and DTP kept in...
Aiming at the increasingly serious pollution and ecological damage in mining cites, environmental information urgently are urgently needed to provide basis and decision-making for the economic transition of mining cites. This article describes main environmental problems existing in mining cites, as well as ways of monitoring these major environmental problems, such as the Landsat TM images are used...
