基于GIS的长沙市村庄名文化景观分布特征浅析

Analysis on Distribution Characteristics of Geographical Names Cultural Landscape in Changsha Community Village Based on Nuclear Density

将长沙市域内各社区村庄名称作为离散点,基于GIS中核密度估计法的空间平滑法为支撑。从自然景观和人文景观两大方面将长沙市域内的社区村庄地名命名方式分为水文、山形地貌、动植物、历史传说、数字方位、姓氏等6类,通过绘制各类社区村庄地名的核密度分布图,从地理区域这一角度分析长沙社区村庄地名景观地理空间分布特征。研究发现:以"山形地貌"、"水文"等元素命名的社区村庄地名占据长沙社区村庄地名的绝大部分,并且各类型地名的核密度空间分布特征与当地的自然山水环境、历史时期的军事、生产生活、社会变迁的相对频繁程度以及人口密度情况高度吻合。

Make the name of each community village in Changsha City as a discrete point,The support of spatial smoothing method based on kernel density estimation method in GIS. From two aspects of natural landscape and humanistic landscape,then put the name of community village names in Changsha City divided into six categories： hydrology,mountain landform,flora and fauna,historical legends,Digital azimuth,surname,etc. Mapping the nuclear density distribution of the names of villages in various communities,Analysis of geographical spatial distribution of geographical names in Changsha community Village from the perspective of geographical area.The study found that the name of the village community named after the ＂ mountain-shaped landform＂ and ＂ hydrology＂ occupies the most of the name of the community in Changsha village,and the spatial distribution of the nuclear density of each type of place names is consistent with the local natural landscape environment,the military,productive life,the relative frequency of social changes and density of population.
