【摘要】 自国家重新提出土地整理以来,全国广泛开展了土地整理实践,并在保证国家粮食安全、实现耕地总量动态平衡、解决“三农问题”和建设社会主义新农村等方面发挥了巨大作用。我国初期的土地整理以增加耕地为主要目标。随着土地整理事业发展,提高耕地质量、改善生态环境等目标逐渐得到重视,但是由于耕地质量、生态环境的区域差异性及难以量化性,区域土地整理规划对其难以定量要求。科学的区域土地整理应在综合分析区域自然、社会经济条件,定量确定土地整理时空分布基础上进行。随着土地整理实践的开展,目前已有大量项目竣工验收进入运行阶段,这些项目决策是否正确、预期目标和效益是否实现等尚不明确,急需进行后评价。因此进行区域土地整理时空配置及其项目后评价理论与方法研究,定量地进行区域土地整理目标时空配置、土地整理模式空间配置和土地整理项目后评价,已成为当前提高区域土地整理规划水平和项目决策管理水平,实现土地资源可持续利用和保持我国土地整理事业健康发展亟待解决的重要课题。本文采用地理信息系统技术及数学定量评价模型对区域土地整理时空配置及其项目后评价理论和方法进行了系统的研究。论文主要研究内容和结论如下:1、在系统分析、总结国内外土地整理研究动态和相关理论基础上,提出了区域土地整理时空配置的基本内涵,分析了区域土地整理时空配置的理论基础,认为配置内容包括土地整理目标时空配置和土地整理模式空间配置。2、提出了当前我国开展土地整理的总体目标是实现土地资源可持续利用和社会经济协调发展,具体包括五个子目标:增加耕地面积,提高耕地质量,改善生产条件,改善生态环境和景观,促进区域协调发展。利用GIS技术和数学模型,研究了区域土地整理目标时空配置的理论和方法:以地貌图和土地利用现状图叠置划分评价单元;根据土地整理措施对土地整理目标的影响,分目标建立评价指标体系;综合考虑土地整理措施对评价指标的影响和评价指标对土地整理目标的影响确定评价指标权重;根据土地整理的目的和成本效益最大化原则,建立单因子评价隶属函数;在此基础上建立了基于指数和法的综合评价模型。研究提出区域土地整理在空间上分为整理区和不整理区,整理区在时间上分为近期、中期和远期,根据土地整理目标评价结果将区域土地整理划分为四区三期:近期土更多还原

【Abstract】 Since land consolidation was again put forward by our nation, land consolidation practice has been widely carried out and played an important role in ensuring nation food safety, realizing the gross cultivated land dynamic equilibrium, solving“San Nong Issue”and building the new socialism countryside. The main aim of the earlier land consolidation in our country was to increase cultivated land area. Along with the development of the land consolidation industry, more attention has been paid to enhancing land quality and improving environment. While the land quality and environment is variable in different regions and is difficult to quantify, it is difficult to meet request for quantitative regional land consolidation. Scientific land consolidation should be carried out on the basis of synthetically analyzing the natural, socio-economic conditions, quantitatively determining the spatio-temporal collocation of land consolidation. Along with the development of the land consolidation practice, at present many projects have been checked, approved and come into running. To make sure that the decision-makings of these projects are right and the anticipated aim and effect are realized, the post-evaluation will be needed. So studying the theory and method of the regional land consolidation spatio-temporal collocation and project post-evaluation, quantitatively carrying throuth the regional land consolidation spatio-temporal collocation, the land consolidation pattern spacial collocation, and the land consolidation project post-evaluation has been an important and urgent task to increase the programming level of the regional land consolidation and the management level of the project decision-making, to realize the sustainable utilization of the land resources and to maintain the healthy development of our land consolidation career.With the GIS technique and the mathematic quantitative evaluation model, the dissertation systematically studied the theory and method of the regional land consolidation spatio-temporal collocation and the project post-evaluation. The main study contents and conclusions were as follows:1. On the basis of analyzing and summarizing the land consolidation study trends at home and abroad and its correlative theory, the dissertation put forward the meaning of the regional land consolidation spatio-temporal collocation, analyzed its theory foundation, and considered that the collocation contains regional land consolidation aim spatio-temporal collocation and pattern spatial collocation.2. The total aim of the land consolidation was to realize the sustainable utilization of the land resources and the socio-economic coordinate development, which includes five sub-aims:更多还原
