The researches combined land suitability evaluation and decision support system need to be improved. For the existed problems that land suitability evaluation systems based on GIS are lack of spatial decision support capabilities and the poor communication among urban planners, land managers and geological experts, a knowledge-based decision support system on land suitability evaluation is developed...
Urban land intensive use is very important to China.Traditional intensity evalua- tion methods of land use is highly influenced by man's subjective impact,thus the evaluation result is not accurate enough. In this paper, Radial Basis Function Network (RBFN) was set up to assess the urban land intensive use.Ezhou Municipal in Hubei province was taken as a case study. The results show that urban land...
Geological data is one of the carriers of geosciences information, and the important foundation information support work of the mineral resources exploration, infrastructure construction and land use planning. According to the characteristics of geological data and service organization of geological data socialized, service polices, service content, and scientificity and operability principles, the...
Urban construction land suitability evaluation is an important reference on urban construction land planning and use potential analysis. With the support of the GIS and Back-propagation (BP) neural network, the suitability of the Hangzhou urban construction land was divided into four levels: a construction land suitability zone I suitable for super high-rise and high-rise buildings, a construction...
Taking grid system as the basic of land management, this paper focused on the establishment of county land and resources management information system based on grid system. Presentation layer, application layer and data layer were proposed to construct the frame of county land and resources management information system. After the principles of grid dividing been clear, methods and thoughts based...
Spatial data exchange and system interoperate have become crucial technologies in land resources informatization. Due to the land resources data is accessed using a variety of GIS platforms, and the management systems are developed by different development languages, the data exchange model must support platform-independent solutions implemented in distributed heterogeneous environments. This paper...
Construction land suitability evaluation is essential for urban development decision. Back Propagation Neural Network (BPNN) is suitable for the non-linear issue. In this study, BPNN architecture has been set up, with 9 neurons of input layer and 4 of output layer. The neurons of input layer include indices related to topography, engineering geology, hydro-geology, and geo-hazard, which are determined...
Construction land location advantages and agricultural land suitability evaluation are the most important basis for land use decision in urban region. This article focuses studying on Hangzhou case, an urban region with very rapid construction expansion. In this study, GIS is using for spatial analysis and mapping, while K-Means Clustering (KMC) and BPNN for attribute data process. Factors including...
The South Florida Ecosystem Portfolio Model (EPM) prototype is a regional land use planning web tool that integrates ecological, economic, and social information and values of relevance to decision-makers and stakeholders. The EPM uses a multi-attribute evaluation framework that builds on GIS analysis and spatially-explicit models that characterize a wide array of important ecological, economic, and...
The occurrence of Geotechnical catastrophe caused by high slope has been a serious constraint on economic development of the mountainous city. A mountainous city high slope risk management information system based on the GIS is established by integrating the mountainous city high slope hazards risk evaluation model with graphic processing and spatial analysis function of the GIS together. The system...
Agricultural land suitability evaluation is the most important base for land sustainable use and especially important in urban region for urban expansion decision. This article is studying on Hangzhou case, an urban region with rapid area's expansion. GIS is using for spatial analysis and mapping, while BPNN for evaluation data process. Topography features, soil conditions, agricultural infrastructure,...
In the Three Gorges reservoir, considering damage to residents and man-made structures by natural hazards, landslide is the most important disaster in the new county seat of BaDong. For this status, landslide hazard zonation is an effective solution for land management. Firstly, based on the analysis of the landslide geological background, by reducing the material composition and historical geological...
In this paper, considering geological environment and landslide development in New Badong County, 11 representative factors are decided to assess landslide hazard in New Badong County. By using the Artificial Neural Network landslide hazard evaluating model and the advantages of GIS technology in image processing and space-analysis, landslide hazard zonation of New Badong County is compiled. The result...
Natural and anthropogenic (e.g. land cover/land use change) processes can lead to ecosystems change dramatically on timescales from years to decades. Especially, land cover/land use changes by mining can have drastic impacts on ecosystems and basin-wide water budgets. Phosphate rock is an important strategic resource. China and U.S. are two major phosphate reserves counties in the world and both facing...
Industrial wasteland tourism has rapidly developed in China. In this review, we discussed the progress in tourism resources and tourism planning, including value evaluation of tourism resources, resources and products development, development orientation of tourism, tourism landscape planning method and technology, and the international successful cases. The results show that in contrast to other...
In this paper, the author taking the geological problem of environment and occurred geological disasters evaluating objects, apply GIS HAP to evaluate three subsystems of rock environment, environmental soil, water environment which affect the quality of geological environment of Wuhan megalopolis. By analyzing the main factors which affect the subsystems, the author establishes subsystem hierarchy...
Land suitability is the base of land use planning and decision, especially in urban region. Current research is limited in suitability of single land use type or evaluation of unidirectional factorspsila influences, such as factors of geology environment, location & economic, or geochemistry, etc.. This article focuses on Hangzhou urban area land use suitability evaluation, in which construction...
