【摘要】：農(nóng)村居民點用地是我國農(nóng)村土地利用的重要組成部分。長期以來,我國的農(nóng)村居民點存在規(guī)劃滯后、忽視建設(shè)、管理不嚴的現(xiàn)象,表現(xiàn)為農(nóng)村居民點普遍存在布局散亂、規(guī)模小、戶均占用土地面積大等問題。在未來一段時期內(nèi),農(nóng)村居民點仍將是農(nóng)村人口聚居的主要形態(tài)和場所。隨著新農(nóng)村建設(shè)、城鎮(zhèn)化以及城鄉(xiāng)建設(shè)用地“增減掛鉤”工作的推進,農(nóng)村居民點合理撤并可大幅度減少農(nóng)村居民點用地面積,改善生態(tài)環(huán)境,提高生活質(zhì)量。如何合理布局現(xiàn)有居民點是擺在我們面前的一個難題。因此,需要通過對農(nóng)村居民點空間布局優(yōu)化方法的研究,利用科學(xué)的手段合理地制定農(nóng)村居民點空間布局優(yōu)化方案,為土地利用總體規(guī)劃、鎮(zhèn)村布局規(guī)劃編制提供理論和決策依據(jù)。 本文基于農(nóng)村居民點空間布局的合理需求,研究農(nóng)村居民點空間布局優(yōu)化方法,分析了布局優(yōu)化研究中的關(guān)鍵因素并加以改進,以金壇市朱林鎮(zhèn)為例進行了驗證。本文的主要研究內(nèi)容如下： (1)總結(jié)了農(nóng)村居民點綜合影響力的影響因素。這些影響因素可以分為反映農(nóng)村居民點自身蘊含特點的內(nèi)部因素和反映農(nóng)村居民點被賦予的社會特性的外部因素。對農(nóng)村居民點綜合影響力進行評價時,需從內(nèi)部因素和外部因素兩個方面進行。 (2)研究了空間對象空間影響范圍的劃分方法,并在總結(jié)現(xiàn)有方法優(yōu)缺點的基礎(chǔ)上,提出了利用加權(quán)Voronoi圖擴展斷裂點模型,對農(nóng)村居民點影響勢力范圍進行劃分的方法,以此確定居民點布局優(yōu)化方案。 (3)針對當(dāng)前已存在的加權(quán)Voronoi圖生成軟件不能滿足研究需要的問題,利用C#語言,實現(xiàn)了基于ArcEngine的加權(quán)Voronoi圖的生成軟件,并和其它軟件生成結(jié)果進行對比分析。 (4)以朱林鎮(zhèn)為實例研究區(qū)域,驗證了農(nóng)村居民點空間布局優(yōu)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.
