摘要:
[目的]通过研究乡村聚落的空间结构和影响因素,可以揭示人类活动与生态形成的机制,对南阳市乡村聚落空间分布的优化和重构具有重要意义。[方法]文章利用渐变尺度空间结构度量法、最近邻指数模型和分布密度对乡村聚落的空间分布特征进行分析,用探测力指数对影响因素进行分析,定量探究南阳市乡村聚落的空间分布特征和驱动因素。[结果]VCM曲线分析结果表明6370%的乡村聚落与相邻聚落的距离在500~1 000m内,该范围内乡村聚落比较集中。通过研究距离城镇的距离与乡村聚落分布的关系,发现距离城镇越远,乡村数量越少; 距离城镇越近,乡村的数量越多。南阳市乡村聚落的空间分布最邻近指数N=0886 3,属于集聚分布,各县乡村聚落的分布密度差异较大。[结论]该文利用不同的模型对南阳市乡村聚落的空间分布特征进行研究,探测到乡村分布的特征及影响乡村聚落空间分布的决定性因素。在城镇化的进程中,乡村空间分布的重构应该以集约用地、提高有效耕地面积为前提,合理安排土地结构的有效利用,并结合当地的资源条件因地制宜发展农村经济。

Abstract:
By studying the spatial structure and influencing factors of rural settlements, the mechanism of human activities and ecological formation can be revealed, which is of great significance to the optimization and reconstruction of the spatial distribution of rural settlements in Nanyang. In this paper, the spatial distribution characteristics of rural settlements were analyzed by variable clumping method (VCM), nearest neighbor index model and distribution density, and the influencing factors were analyzed with the detection force index. And the spatial distribution characteristics and driving factors of rural settlements in Nanyang were quantitatively explored. The results of VCM curve analysis showed that 63.70% of the rural settlements had a distance of 500 to 1000 meters from the adjacent settlements, and the rural settlements were relatively concentrated within this range. Through the study of the relationship between the distance from the town and the distribution of rural settlements, it was found that the farther away from the town, the less the rural population, and the closer the distance from the town, the more the rural population. The spatial distribution of rural settlements in Nanyang city was the closest to the index N (0.8863), which belonged to the agglomeration distribution, and the distribution density of rural settlements in each county was quite different. In this paper, different models are used to study the spatial distribution of rural settlements in Nanyang, and the characteristics of rural distribution and the decisive factors affecting the spatial distribution of rural settlements are detected. In the process of urbanization, the reconstruction of rural spatial distribution should be based on intensive land use, increase the area of effective cultivated land, reasonably arrange the effective use of land structure, and combine with the local resource conditions to develop rural economy according to local conditions.
