林口县绿化示范村聚落空间分布特征与影响因素

Spatial Distribution Characteristics and Influencing Factors of Green Demonstration Village in Linkou County

以林口县作为基本空间单元,展开22个绿化示范村聚落空间分布特征及影响因素的研究,运用了无人机多视图影像三维重建技术获取资料,基于地理信息系统空间分析技术,从高程、坡度、坡向、流域、交通和区域环境等因素特征,量化分析绿化示范村与自然环境和人文环境各影响关系,对绿化示范村聚落空间分布特征及影响因素展开科学理性思维探讨,客观认知黑龙江地域典型乡村聚落空间分布及影响因素。量化与分析结果表明:样本村落聚合程度与地貌特征关系较突出,地势直接影响着村落的分布,低海拔洪积平原低海拔冲积洪积台地、低海拔丘陵和低海拔小起伏山地的村落相对密集,地形坡度在0~5°是普遍选择的范围,坡向分布呈现一定的向阳性,但阳性面和阴性面数值反差并不大,优先选择临近河流或主要道路区域分布,中心镇与行政村的分布之间的空间关系呈现较为紧密的关系。

Taking Linkou County as the basic space unit,the study was conducted to study the spatial distribution characteristics and influencing factors of settlements in 22 green demonstration villages.With the data from UAV multi-view image 3D reconstruction technology,using GIS spatial analysis technology,the relationship between green demonstration village and natural environment and human environment was analyzed quantitatively from the characteristics of elevation,slope,slope direction,watershed,traffic and regional environment,and scientific and rational thinking on the spatial distribution characteristics and influencing factors of settlements in green demonstration villages and objective cognition of spatial distribution and influencing factors of typical rural settlements in Heilongjiang region were set.The results of quantification and analysis show that the degree of aggregation of sample villages has a prominent relationship with geomorphological characteristics,the topography directly affects the distribution of villages,the villages of low-altitude alluvial platform,low-altitude hilly area and low-altitude small undulating mountain area are relatively dense.The topographic slope of 0-5°is a generally chosen range,and the slope distribution shows a certain positive direction,but the numerical contrast between positive surface and negative surface is not large,the distribution of adjacent rivers or main roads is preferred,and the spatial relationship between the distribution of central towns and administrative villages is relatively close.
