Evaluation Of Urban Land Application Of Intensive

The socio-economic and urban development in the rapid advance of today, extensive land resource use, social stability and development of a serious impact. Therefore, how to manage better urban land use control and rational allocation of land resources to achieve sustainable use of land to become the focus of attention of Governments, has also become the focus of academic attention. Urban land use evaluation study, in this context came into being, and intensive evaluation index system, which became the basis for the most part of the evaluation process is the core component.According to "Evaluation of urban land use intensification potential technical regulations (Trial)" (hereinafter referred to as trial order) description of the evaluation of all actions required to establish evaluation index system of a large number of indicators on the basis of data collection, and evaluation in the intensive The data not only the data related to a wide range of data sources is also extremely complicated. With intensive evaluation of urban development and the gradual implementation throughout the evaluation, due to traditional data collection and processing mode can only achieve macro-, meso-evaluation of the defect, causing it to gradually adapt the macro, meso and micro levels of the evaluation of spatial scale request. So, how micro-data collection, were collected, related to the global collection to evaluate the urban land to achieve the macro, meso and micro levels of evaluation scales in the evaluation of urban land intensive research work is particularly important.The main research topic is based on existing ground database of urban Chengdu city center-based, as the research area of Chengdu city, the urban land use data were collected to global research, through domestic and international kinds of theory-based research, in Chengdu, "second Five-Year" plan and the construction of Chengdu "World Garden City" in the background, through the intensive use of the commonly used evaluation of the city evaluation data collection, analysis and comparison of analytical methods, can propose a three-level evaluation of space-scale data acquisition mode, the establishment of Chengdu urban land use assessment based database, enabling users to achieve the macro, meso and micro levels of spatial scale can be used year after year of intensive evaluation of the dynamics.Established urban cadastral database of Chengdu dynamic extraction of data will be involved in the evaluation of land type data from the cadastral database, extracted; The density mapping method, a simple weighting method of region, modified surface domain weighting method, Monte Carlo Lofa discrete spatial data such as the current methods commonly used in the analysis of several methods to select in the Monte Carlo algorithm to evaluate the social statistics related to cases of land-based localization wide distribution, combined with the help analyze the actual situation analysis Based on the evaluation by the more real to support the global distribution of data.Based on the data collection and processing methods of research, the "bottom up" processing mode data collection, through the land based Cadastral Database class data extraction and data on social statistics class space discretization Monte Carlo. Established to support the macro, meso and micro levels of Chengdu spatial structure of urban land use parcel-level evaluation of the underlying database.
