摘要
梯田区传统村落及其梯田系统是我国传统农业文化遗产瑰宝,分析梯田区传统村落空间分布特征对梯田区农业文化遗产保护开发和山水林田湖草系统治理具有重要意义。以贵州省梯田区入选住房和城乡建设部公布的中国传统村落为研究对象,结合GIS核密度估算和地形梯度方法对贵州省梯田区传统村落空间分布特征进行分析。结果发现:从空间数量关系上看,贵州省梯田区传统村落在地理空间分布上具有聚集性,在地州市尺度上的空间分布呈不均匀性,并在地州市内部表现出显著的空间集聚特征;梯田区传统村落主要集中在少数民族地区,其中,黔东南苗族侗族自治州、黔南布依族苗族自治州、铜仁市和安顺市呈现显著密集的分布密度;从垂直特征上看,贵州省梯田区传统村落集中分布在缓坡和缓陡坡,其优势地形梯度等级为第2和第3等级,低地形梯度等级和高地形梯度等级上的梯田区传统村落分布较少,在地形梯度上的分布表现出“中间多两边少”的特点。
The traditional villages and their terrace systems in the terrace areas are the treasures of China’s traditional agricultural cultural heritage.Analysis of the spatial distribution characteristics of traditional villages in terraced areas is important for the conservation and development of agricultural cultural heritage and the system management of mountains,water,forests,fields,lakes and grasses in terraced areas.The article takes the traditional Chinese villages in the terraced area selected by the Ministry of Housing and Urban-Rural Development in Guizhou Province as the research object,analysis of the spatial distribution characteristics of traditional villages in the terraced area of Guizhou Province by combining GIS Kernel Density Estimation and terrain gradient methods.The results of the study found that,in terms of spatial-quantitative relationships,traditional villages in the terraced areas of Guizhou Province are clustered in terms of geospatial distribution,and the spatial distribution at the prefecture-level city scale is heterogeneous and exhibits significant spatial clustering characteristics within the local cities and towns.Traditional villages in the terraced area are mainly concentrated in minority areas,among which,Qiandongnan Miao and Dong Autonomous Prefecture,Qiannan Buyi and Miao Autonomous Prefecture,Tongren City and Anshun City show a significantly dense distribution density.In terms of vertical characteristics,the distribution of traditional villages in the terraced area of Guizhou Province are concentrated on gentle and gently steep slopes,its dominance gradient rank 2 and rank 3,and traditional villages in terraced areas on low terrain gradients and high terrain gradients are less distributed.The feature is showed "more in the middle and less on the two sides" on the terrain gradient.
