【摘要】：科学进行农村居民点优化布局,对实施农村居民点整治,实现城乡一体化发展意义重大。该文以河南省新郑市为例,研究了农村居民点优化布局的方法和分区整治策略。基于中心地理论,设计了农村居民点理想布局模型,在农村居民点适宜性评价基础上,进一步提出了农村居民点适宜性迭代评价的方法,设计了程序算法,利用Python语言和Arc Py类库实现了软件工具开发。研究结果表明:根据农村居民生产和生活需求设计的理想村庄布局模型参数为:村庄之间的标准距离2.5 km,最大耕作半径为1.44 km,聚落腹地面积541.27 hm2。新郑市农村居民点适宜性评价综合分值呈现出东高西低的非均匀分布,而迭代评价结果呈现出相对均匀的分布,利用该结果进行村庄布局优化更加合理。进行村庄优化布局,设置了17个中心村,103个基层村,其余为拆迁村,并将拆迁村划分为政府主导型和规划引导型2类,针对不同类型的村庄提出了对应的整治策略。研究结论认为,农村居民点迭代评价方法得到的结果,更加科学合理,该结果通过规划引导,可实现农村居民点的合理演化,该文的方法可为相关研究提供参考和借鉴。
[Abstract]:It is of great significance to optimize the layout of rural residential areas scientifically and realize the integration of urban and rural areas. Taking Xinzheng City, Henan Province as an example, this paper studies the method of optimizing the layout of rural residential areas and the strategy of district regulation. Based on the central land theory, the ideal layout model of rural residential land is designed. On the basis of the evaluation of rural residential suitability, the iterative evaluation method of rural residential suitability is put forward, and the program algorithm is designed. The software tool development is realized by using Python language and Arc Py class library. The results show that the ideal village layout model parameters are: the standard distance between villages is 2.5 km, the maximum tillage radius is 1.44 km, and the settlement hinterland area is 541.27 hm ~ 2. The comprehensive score of the evaluation of rural residential area in Xinzheng city shows a non-uniform distribution of the east high and the west low, while the iterative evaluation results show a relatively uniform distribution, so it is more reasonable to use the result to optimize the village layout. In order to optimize the layout of villages, 17 central villages, 103 grass-roots villages, and the rest of them were divided into two types: government leading and planning leading, and the corresponding remediation strategies were put forward for different types of villages. It is concluded that the results obtained by iterative evaluation of rural residential areas are more scientific and reasonable. The results can realize the rational evolution of rural residential areas through planning guidance. The method in this paper can provide reference and reference for relevant research.
