【摘要】：农村居民点用地是我国农村土地利用的重要组成部分。长期以来,我国的农村居民点存在规划滞后、忽视建设、管理不严的现象,表现为农村居民点普遍存在布局散乱、规模小、户均占用土地面积大等问题。在未来一段时期内,农村居民点仍将是农村人口聚居的主要形态和场所。随着新农村建设、城镇化以及城乡建设用地“增减挂钩”工作的推进,农村居民点合理撤并可大幅度减少农村居民点用地面积,改善生态环境,提高生活质量。如何合理布局现有居民点是摆在我们面前的一个难题。因此,需要通过对农村居民点空间布局优化方法的研究,利用科学的手段合理地制定农村居民点空间布局优化方案,为土地利用总体规划、镇村布局规划编制提供理论和决策依据。本文基于农村居民点空间布局的合理需求,研究农村居民点空间布局优化方法,分析了布局优化研究中的关键因素并加以改进,以金坛市朱林镇为例进行了验证。本文的主要研究内容如下： (1)总结了农村居民点综合影响力的影响因素。这些影响因素可以分为反映农村居民点自身蕴含特点的内部因素和反映农村居民点被赋予的社会特性的外部因素。对农村居民点综合影响力进行评价时,需从内部因素和外部因素两个方面进行。 (2)研究了空间对象空间影响范围的划分方法,并在总结现有方法优缺点的基础上,提出了利用加权Voronoi图扩展断裂点模型,对农村居民点影响势力范围进行划分的方法,以此确定居民点布局优化方案。 (3)针对当前已存在的加权Voronoi图生成软件不能满足研究需要的问题,利用C#语言,实现了基于ArcEngine的加权Voronoi图的生成软件,并和其它软件生成结果进行对比分析。 (4)以朱林镇为实例研究区域,验证了农村居民点空间布局优化方法。
[Abstract]:Rural residential land is an important part of rural land use in China. For a long time, the rural residential areas in our country have some problems, such as lagged planning, neglect of construction and lax management, such as scattered layout, small scale, large land area occupied by households and so on. In the future, rural settlements will still be the main form and place of rural population. With the development of new rural construction, urbanization and "increasing or decreasing link" of urban and rural construction land, the reasonable withdrawal of rural residential land can greatly reduce the area of rural residential land, improve the ecological environment and improve the quality of life. How to reasonably distribute the existing residential areas is a difficult problem in front of us. Therefore, through the research on the optimization method of rural residential land spatial layout, we should use scientific means to rationally formulate the rural residential spatial layout optimization plan, and make the overall land use planning. Town and village layout planning provides theoretical and decision-making basis. Based on the reasonable demand of rural residential area spatial layout, this paper studies the optimization method of rural residential land spatial layout, analyzes the key factors in the study of rural residential land spatial layout optimization and improves it, and verifies it by taking Zhu Lin Town, Jintan City, as an example. The main contents of this paper are as follows: The influence factors of the comprehensive influence of rural residential areas are summarized. These factors can be divided into internal factors reflecting the inherent characteristics of rural settlements and external factors reflecting the social characteristics of rural settlements. When evaluating the comprehensive influence of rural residential areas, it should be carried out from two aspects: internal factors and external factors. (2) the method of dividing the spatial influence range of spatial objects is studied, and on the basis of summarizing the advantages and disadvantages of the existing methods, a method of dividing the influence sphere of rural residential area by using weighted Voronoi diagram to extend the fracture point model is put forward. This determines the residential area layout optimization program. In order to solve the problem that the existing weighted Voronoi graph generation software can not meet the needs of the research, a weighted Voronoi graph generating software based on ArcEngine is realized by using C # language, and the results are compared with other software. Taking Zhulin Town as a case study area, the optimization method of rural residential spatial distribution is verified.
