Communication System GIS is an important foundation of digital city construction and the basis of GIS construction is the choice of network platform. In this paper, based on past research and reality, it builds a software selection index system which includes three aspects-economy, universality and technicality. It conducts the evaluation of typical domestic and foreign software and analyzes its rationality...
Based on RS and GIS, using landscape pattern method, this thesis researched the land use pattern in Karst area effected by topography, and also analyzed the land use pattern spatio-temporal change, taking the case of Guilin City. The research indicated that topography factors, such as elevation, slope and aspect influencing land use pattern respectively and differently. As the increasing of altitude,...
Urban morphology is an overall form of urban spatial structure as an external outline shape of urban space. Study on the evolution of urban morphology and identification of its expansion direction is related to the sustainable development of urban spatial structure. So, it has been an important research field of urban planning subject. This paper analyzed the evolution of urban morphology and identification...
Taking Jiangxia District in Wuhan City as the research region by using RS and GIS comprehensively. According to the country secondary category and classification standard interpretation. Reveal the characteristics of the fractal structures of the distribution of land use types. Explore the significance of the fractal on land use types. The fractal dimensions (D) and stability indexes (S) of first...
Remote Sensing (RS) and Geographic Information System (GIS) are important technologies for the sustainable management of ecological environment. In this paper, Landuse information is obtained by integrating the maximum likelihood classification (MLC) and neural network classification (NNC) method, which can realize the automatic extraction and recognition of land-use in Beijing City from remote sensing...
Landscape Ecology is a new field of the macro-ecological research. Based on the principle of landscape ecology and supported by 3S technology, the landscape pattern of land use in Qichun County is quantitatively analyzed in this paper. This study mainly uses the data collected by GPS and the ERDAS IMAGINE 9.1 to deal with the satellite remote sensing image data of Indian IRS P6 in 2OO5. Then uses...
Land is vitally related to human existence and development. It has being evidently proved that sustainable utilization of land resources is the core problems of sustainable development. Taking Beijing city as a model case, we used the Delphi and Analytic Hierarchy Process (AHP) methods to assess the land intensive use level from 1996 to 2005. By building respective index system of intensive land use,...
The temporal-spatial patterns and incentives of the urban land expansion are studied, taking Wuhan city as a case. The construction land data was captured according to land use database standard of CAS from Landsat TAT images of 1995, 2000 and 2005 respectively. With the Supermap GIS software platform, the spatial analysis of construction land was made during two periods of 1995-2000 and 2000-2005...
Based on the MSS datum in 1975 and Landsite TM datum in 1987, 1995, 2000 and 2005, monitored the land use change in the Reservoir Area of three Gorges was conducted with the support of several indexes to reflect the temporal-spatial changes during 30 years. The results as following, (1) The areas of cultivated land, forestry land, grass land decreased but the areas of construction land and water area...
Geomorphologic elements such as valley, ridge are structural information to represent natural geomorphology in spatial extension and distribution. The united Delaunay triangulation network methodology makes an improvement over traditional triangulation method, with its capability of detecting human recognizable bends. Although this united Delaunay triangulation network is more suitable for terrain...
Taking the Northern Slope of the Tianshan Mountains (NSTM) as the study area, we investigated into the oases LUCC and information entropy change by using RS, GIS and statistical model. The results showed that, (1) Establishing mathematical models of the range, speed and trend index of LUCC, especially the model of LUCC trend and state, the state and trend of oasis LUCC can be deeply researched. Meanwhile,...
Land use/cover change (LUCC) is a key aspect of global environment change and in a sense indicates the influence of human activities on natural environment. Regional case study is the core of LUCC research. Taking the Hotan river basin, an oasis area of the Tarim river origin basin, as an example, Supported by RS and GIS technology, this paper reconstructed LUCC patterns in three periods of 1960,...
Urbanization has become an important contributor for global warming and urban air temperature is rising gradually in all the cities. It means that urban land use and land cover (LULC) changed became critical in determining the urban environment quality. This paper presents an integrated study to investigate and identify landscape pattern which have the influence to increase of land surface temperature,...
In the past thousands of years, the Grand Canal not only promoted political, economic and cultural development in China, but also formed the pattern of cities which lie along the canal called ldquoCanal Citiesrdquo. To comprehend the relationship between the city and the canal can benefit the urban planning and development. Remote Sensing and Geographical Information System technology enable us to...
It is well known that economy has developed rapidly in Eastern China since the reform and opening up, while the quality of eco-environment is becoming worse and worse. In the presented contribution, the speed and rationality of the urban growth in Suzhou city at various stages were studied, using the data of Landsat TM satellite images in 1995, 2000 and 2005. Moreover, the ecological footprint and...
As widespread features of landscape and human disturbance paths, road networks bring forth many ecological effects and affect the regional land ecological security. In this paper, the methods of GIS buffer were used to elucidate the influence of roads on landscape and assess the road impacts on land ecological security in Hengshan county. Land use change greatly with different buffers. Landscape fragmentation...
The paper think that construction land expansion result from the development of social economic and the growth of population in the overall land use planning, and contain quantity increased and spatial configuration optimal. Based on the analysis, this paper construct an optimal allocation statistical model with two sub-models, one is to forecast the quantity of construction land required; another...
Within the framework of evidence theory, the construction of mass functions remains an important problem which can considerably influence final results. Several propositions of construction are available in literature but generally, these methods do not consider the belief masses on compound hypotheses and do not exploit all the strengths of the theory. In this article, we propose two methods of grouping...
Land use/cover change is an important issue for global environmental research. Combined with the use of GIS, this paper explores the utilities of CBERS images to analyze the land use/cover changes in the city of Lianyungang, and analyzes the driving forces by the principal component analysis. Results show that during the past 8 years, the local land use pattern has changed greatly, especially for...
Satellite images are now used as the primary source of spatial information for land-use pattern analysis. In this paper, land-use information is extracted by the maximum likelihood classification (MLC) and neural network classification (NNC) method, which is a combinative methodology of automatic extraction and recognition of land-use in Beijing City from remote sensing data. The temporal and spatial...
