This paper analyses the main reasons of it . and then through the building up different evaluation index systems and methods , the authors give the evaluation conclusion about the urban intensive use in deyang 在此基础上通过不同层次的评价方法，对德阳市土地集约利用状况进行实地调查与研究，综合评价德阳市城市土地集约利用水平。
Second , we need to work quickly to establish or improve standards for conserving energy , water , land and materials in all industries , develop key projects that save energy and materials , and promote more intensive utilization of land 二要抓紧制定和完善各行业节能、节水、节地、节材标准，推进节能降耗重点项目建设，促进土地集约利用。
This paper introduces the intensive and economical utilization of land based on gis and rs technologies , and according to the practical situation and developing trend of the urban land utilization , analyzes on the potential evaluation information system for the intensive utilization of land 介绍了基于gis和rs技术的土地集约与节约利用研究,根据城市土地利用现实情况及其发展趋势,分析土地集约利用潜力评价信息系统。
To suit " digital territory " project and answer the need of nation land resource department , intensive use estimation system should be developed to realize the automation of the first phase of this work and dynamic management and update 为了配合“数字国土”建设，按国土资源部要求，进行“城市土地集约利用潜力评价信息系统” ( intensiveuseestimationsystem ， iues )开发，以实现此项工作的一期自动化，日常管理更新动态化。
During the process , the urban development , especially the construction of the urban land structure , was neglected by the local governments , which brings the degrading of the city functions , the extending of the land area and the confusion of the land use structure , etc . 本文依托于辽宁省国土规划? ?辽宁西部地区区域发展与生态恢复规划研究项目( 2005tp043 ) ,对城市土地集约利用内涵进行界定,分析了城市土地集约利用的影响因素。
The train of thought is : on the basis of the different factors and importance which effect the land use intensive level , economic benefit and environmental benefit , it determines the evaluation index system and the weight value . based on the standardized firsthand data , it defines weighted sum to found a composite index . thus arranging the composite index in mathematical order , it fixes quantitatively the land use intensive level , economic benefit and environmental benefit to demonstrate quantity , structure , scale , benefit and distribution on land use in small - towns of chongqing 其评价思路为:根据影响小城镇土地集约利用水平、土地利用经济效益、环境效益的各因子及其重要程度的不同，确定评价指标体系及指标权重，在对原始数据标准化的基础上，按照指标权重，将各指标值加权求和，得到小城镇土地集约利用、土地利用经济效益、环境效益的综合指数，按综合指数从大到小的顺序对各评价单元进行排序，定量地确定小城镇土地集约利用水平、土地利用经济效益、环境效益，从而找出重庆市小城镇土地利用的数量、结构、规模、效益特征及布局特点，根据小城镇土地利用与区域社会经济发展的互动关系，分析存在的问题及原因，为小城镇土地利用优化配置、小城镇建设用地指标管理提供借鉴。
Based on the definition of urban land intensive use , and utilizing index data of urban land use in wuhan city , the paper selects the corresponding evaluation index system to make a quantitative analysis of intensivism extent of urban land use and expects to get a comparatively exact conclusion through the comparative appraisal among many cities 摘要在界定城市土地集约利用内涵的基础上，以此为标准，结合武汉市城市土地利用的各项指标数据，选取相应的评价指标体系，首先应用层次分析法构建评价模型并确定指标权重，对武汉市城市用地集约程度进行定量化评价；同时应用多城市对比评价方法与其进行评价效果的比较，以期得到该市土地利用较准确的评价成果。
Based on a summary of the basic connotation of intensified land use , this paper analyzes the current state of construction land use in yiyang city , hunan province , and applies an improved topsis method to conduct a macro assessment and analysis of the degree of intensified land use in the city , revealing difference in intensified level of regional construction land , finally , the paper proposes countermeasures and suggestions for improving intensified constructing land use 摘要在归纳概括土地集约利用的基本内涵的基础上，对益阳市域建设用地现状进行分析，总结了建设用地利用的现状特征及变化趋势，从土地配置效率、用地结构与布局、土地利用强度、土地投入产出等方面建立了一个宏观评价指标体系，采用改进的topsis法对益阳市土地集约利用程度进行了宏观角度的评价与分析，揭示区域内建设用地集约水平的差异，进而提出若干有益于土地集约利用的对策和建议。
Since data quantity of the appraisement index , standards and basic geography information etc . related to urban land intensive use potential estimation is big , how to raise working progress , avoid the information of data transition to lose , and reflect fast , scientifically , accurately the degree of intensive use for urban land is one of the current problems that urban land intensive use potential estimation will solve 由于城市土地集约利用潜力评价涉及的评价指标、各类标准、基础地理信息等的数据量大，如何能既提高工作进度，又避免数据转换过程的信息丢失现象，快速、科学、准确的反映城市土地的集约利用程度，是当前城市土地集约利用潜力评价要解决的问题之一。
( 2 ) the theory foundation of iues development has explained the relevant concepts and their intensions for urban land intensive use potential estimation , made brief explanation for district location theory , land price theory , minimum factor restriction law , land pay law , ecological resource optimization law , landscape ecology theory and other basic theory ( 2 ) iues开发的理论基础解释了城市土地集约利用潜力评价的有关概念及内涵，对区位理论、地价理论、最低因子限制律、土地报酬规律、生态资源优化律、景观生态学理论等基础理论做了简要分析说明。
