基于土地功能的未利用地多宜性评价及优化配置研究-土壤学专业论文.docx

以土地功能评价为基础，在黄骅市未利用地宜耕、宜建、宜生态评价结果基础上， 以土地功能评价为基础，在黄骅市未利用地宜耕、宜建、宜生态评价结果基础上， 用遗传算法作为权衡模型实现的基础方法，通过合理设置权衡要素(模型变量)，设 定适宜性、效益、集中连片性等多个目标及权衡关系的约束条件，进行权衡模型的求 解。提出了一种基于权衡模型的环渤海县域尺度未利用地适宜性优化配置的实现方 法。从而为区域未利用地的高效开发利用提供科学依据。 综上所述，本研究为区域未利用地适宜性的确定方法提供了一个新的研究视角： 基于土地结构与土地功能关系辨析的土地功能分类一土地功能评价一基于功能评价 的未利用地适宜性确定一未利用地适宜性多目标优化配置，这一思路为区域未利用地 资源的合理开发及可持续利用研究提供了理论框架，研究结果不仅可以为编制区域土 地利用规划、优化土地利用格局提供理论依据，而且可以为制定土地管理政策，促进 区域的协调发展提供科学参考。 关键词：土地功能；未利用地；适宜性评价；优化配置；黄骅市 万方数据 Study Study on Multi—-suitability Evaluation and Optimization Allocation of Unused Land Based on Land Function Author：Chen Ying Major：Soil Science Tutor：Prof．Men Mingxin A．Prof．Wang Shutao Abstract With the continuous development of society and economy in China．some had neglected the protection of the land．Inemcient transitionalland use and contradiction between supply and demand of land iS becoming increasingly severe．How to coordinate the contradiction between land use and maintenance of food security and ecological security had become the key problem to be solved urgently．But at present，the research land function classification，function evaluation and land use was not mature．How to combine the functions of land and land use?Using the evaluation results of land function determined land panem．A consistent method system has not been formed yet．Because of this，this paper took HuangHua city study area．On the basis of deep analysis of the relationship between land structure，property and land function，guided by the theory of sustainable development and Soil Science，combined with GIS，remote sensing and other technical methods，firstly,the concepts summarized on the basis of analyzing the relationship between 1and structure．attribute and the function of the land．Classificatory and definition the land function．And then construct the evaluation index system and evaluation model of land biological production，carrying，ecological coordination and maintenance functions．Evaluate the functions． And based the analysis of the logical rela
