Based on TM remote sensing images in 1989, 2000 and 2008, combining with GIS technology, and the city of Beijing's land use change characteristics in the past 20 years from 2008 will be analyzed. The indicators such as single land use dynamics, land utilization classification index and land use transfer matrix will be used to reveal the changes on range, speed and direction of this study area. On...
Great land use change has taken place in most regions worldwide and such information is urgently needed to help the mankind with rational land use and development. In this paper, land use and change for Xinxiang City in Henan Province of China were analyzed in 1995, 2000 and 2005 by using a series of Landsat Thematic Mapper (TM) satellite data. And spatiotemporal characteristics analysis of land use...
Land Use / Cover Change (LUCC) is an essential component in the field of regional environmental monitoring and economic development analysis. Its motivation is to get an in-depth understanding of dynamic process, leading causes and evolution mechanism of regional land use change, which provide accurate information for land administration to develop local economic development planning and management...
Land use change plays vital roles in regional, social and economic development. Based on three phases of NDVI and climate images acquired in 1982, 1990 and 1998, and fuzzy rule-based classification, this paper took China as a case study to analyze spatial change of land use by combining NDVI, Landscape indices and transformation matrix. The research results indicate that land use has grown more and...
Land use change is recognized as one of the most important factors leading to environmental change. This study analyzed the dynamics of urban land use/cover in landscape fragmentation in Manas River Watershed during 1990-2006, including the centre Town of Manas County, City of Shihezi and part of regimental farm of Division 8. The study area is located in the mid-west of the North Xinjiang Economic...
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...
Taihu Lake basin is among the most developed regions in China, and changes in land use and land-cover change were distinct in last two decades. The rapid economic growth and lagged measures in pollution control have resulted in serious environmental problems in this region. Using Landsat satellite imagery of different periods (1985, 1995, 2000, and 2005), we achieved the land use data in Taihu Lake...
Land use change plays vital roles in regional, social and economic development and global environmental change. Based on three different phases of TM images acquired in 1992, 2000 and 2006, this paper takes Kunming in China as a case study to analyze spatial change of land use and to evaluate urban environment quantitatively by combining Landscape indices and NDVI. Following the theory of landscape...
By using a series of Landsat Thematic Mapper (TM) satellite data, land use change and its landscape ecological effect are analyzed quantitatively in Datong City, Shanxi Province of China. After correlative data processing and interpreting, land use information is extracted in 1988, 1995, 2000 and 2005. Then, the paper mainly focuses on the spatio-temporal analysis of land use change and its landscape...
Songnen Plain is an important grain production bases, but the area of sandy desertification gradually increases. Tailai County of typical sandy desertification region in Songnen Plain is taken as an example, and the data of land use and sand land change are acquired in 1986, 2000 and 2005 by RS and GIS technology, then the influence of land use on sandy desertification is analyzed, finally, characteristic...
This paper presents the methods of dynamic monitoring and prediction model of land use change and their application in Changsha county. Firstly, with the support of remote sense and geographic information system, the land use of Changsha county was categorized into five types. Then growth degree index was introduced to analyze the dynamic evolution process of land use change. Markov model was used...
