Understanding patterns, processes, and consequences of land-cover change requires close linkages among various ecological, socioeconomic, demographic, and behavioral data. In this chapter, we present an interdisciplinary study of human impacts on land cover and panda habitat in Wolong Nature Reserve (China). Wolong is one of the largest reserves (200,000 ha) designated for giant panda conservation,...
For decades, southern China has been considered to be an important source for emerging influenza viruses since key hosts live together in high densities in areas with intensive agriculture. However, the underlying conditions of emergence and spread of avian influenza viruses (AIV) have not been studied in detail, particularly the complex spatiotemporal interplay of viral transmission between wild...
This paper taking Mudanjiang in Heilongjiang Province as the study region, the remote sensing data and topographic map data in forth years as a basis for data, the vulnerability model was evaluated based on the sensitivity, exposure and adaption ability, relevant parameters of model was acquired by GIS and RS technology and mathematic model, and the vulnerability of ecological environment was in a...
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...
Using the closed chamber technique daily changes of net ecosystem carbon dioxide (CO2) exchange (NEE) and ecosystem respiration (Re) were determined in a ryegrass ecosystem on eight separated days at half hour interval from morning to afternoon in Taiyuan basin, Shanxi province of China. The gross primary production (GPP) was calculated as the difference of NEE and Re. The objective of the study was...
Vegetation includes all plant communities that cover the earth surface. Vegetation coverage is the most important index to scale the status of the vegetation of the region, so the vegetation is the composition and the function body of ecological system. Vegetation coverage in different land use types of Miyun reservoir watershed were calculated based on remote sensing images (Landsat 5 TM images)...
A system of wetland monitoring and Eco-health assessment has been set up based on 3S. The system is be made up of information management subsystem, assessment subsystem, prewarn subsystem, other management subsystem. Taken Huixian wetland of Guilin as the object of study, the system made to operating, the result show that the wetland state of health is bad, CEI=0.364. The building of the system is...
Wuhan city is the core city of Wuhan city circle and the major city of the Yangtze River, and the change of water have attracted great attention. Using the techniques of "3S" and landscape ecology, based on 1991 and 2009 Landast TM remote sensing image, integrating with the change of water modeling, transform matrix, the shift of gravity centers and landscape pattern analysis software Fragstats3...
Landscape spatial patterns have profound implications for the functions of ecosystem. Remote sensing is an important tool for monitoring and managing structural changes of protected areas. Based on landscape ecological principles, the paper presents a case study on landscape pattern with the application of satellite remote sensing and GIS data, using dynamic analysis method. Such indices as the patch...
Based on remote sensing(RS) and geographic information system(GIS) technology, the land use range and landscape pattern index were used to study the spatial-temporal change of land use in Pingdingshan mining area, Henan Province, China. We analyze the change of the range and spatial pattern based on remote sensing images in 1978, 1994 and 2006. The results showed: 1) The regional landscape were changed...
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...
Based on methods of lanscape ecology and TM images of the Ebinur lake during the diffierent period, This paper studies the characteristics of landscape pattern, function and its variation. The ecological process, mechanism and intensity of variation influenced by the human activities and physical factors are analyzed in order to offer the countermeasure and references for restoring and reconstructing...
This paper use ETM and GIS date of 2000 year, using ecosystem service evaluation parameter which Costanza advanced, estimate that the ecosystem service function value of wet land and meadowland in Xinjiang ABI lakeside is 8.76×108 RMB/hm2. The contribution rate in the total meadow ecosystem service function value of Sacsaoul desert, tamarix cone, salt marsh, salt meadow are 26.03%, 21.36%, 20.93%,...
The quantitative study of forest regulation temperature was one of keys of evaluation of forest ecological service. The paper studied on the forest regulation temperature by using ALOS data, TM data, field surveying data and the meteorological data in Qingdao. The results were as the following: (1) the decrease temperature function of various species was different; (2) LST and NDVI are the negative...
Mankind currently is facing with the most serious environmental problems, such as the loss of forests, pollution, biodiversity loss, especially CO2 produced by human activities and sharp rise in the concentration of Greenhouse Effect resulted from it, so the global carbon cycle is becoming mankind's major concern. However, analysis of changes in forest biomass is the basis to carbon cycle and dynamic...
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...
As the largest in-land fresh water lake of China, Poyang Lake is also an important wetland in the world. However, the lake area, like the other lake areas of China, has being faced series of ecological and environmental problems and challenges, such as soil erosion, land desertification, drought and flooding disasters, farmland being soiled, pollution, invasive species, loss of biodiversity, and more...
The Northeast shelterbelt project is a part of the Shelter Forest System Program in Three-North Regions of China. By far, the third phase project has been completed, and the fourth phase project is on the point of completion. This paper chose the Yushu, Nong'an, Dehui and Fuyu in midwestern Jilin province as the research areas, selected three phase shelterbelt data and land use data at Sep. 25, 1988,...
Taking Futouhu which is the forth largest lake in Hubei Province as the study object, based on RS and GIS technologies, using the Landsat TM remote sensing images in 1991 and in 2005 as well as local chronicles as basic data resources, combined with field surveys and GPS positioning, the data on the dynamic changes of the area and the types of Futouhu wetland from 1991 to 2005 were obtained, and then...
10-day maximum composite SPOT/VEGETATION NDVI from 1998 to 2007 were collected to assess terrestrial region ecosystem health along the coast in Zhejiang province. Vigor, organization and resilience were the main three characterization of ecosystem health, in this paper the average annual NDVI represented vigor, vegetation percentage and centriod movement represented organization, SLOPE represented...
