武陵山片区农业文化遗产分布特征及影响因素分析

Geographical Distribution and Affecting Factors of Agricultural Heritage Systems in Wuling Mountain Area

为了探究省域内农业文化遗产的地理空间分布特征和影响因素,并为武陵山片区的农业文化遗产保护提供依据,以武陵山片区四省为研究区域,利用该区域内43处农业文化遗产空间点数据,运用最近邻指数、地理集中度系数、集中化指数、空间聚集区分析农业文化遗产的空间分布特征。结果表明:武陵山片区四省农业文化遗产呈团块状分布,具有明显的空间聚集性;农业文化遗产空间差异明显,形成了1个高密度圈和5个次级核心圈,分别以铜仁、宜昌、恩施、武汉、随州、永州为核心,各核心区都有一定的辐射范围。影响农业文化遗产空间分布的主要因素是特定的区位条件、优质的生态环境、丰富的资源条件及独特的民族风情。

In order to explore the geographical spatial distribution characteristics and influencing factors of agricultural cultural heritage at province scale and provide basis for the protection of agricultural cultural heritage in wuling mountain area,We take the four provinces of Wuling Mountain area as a target area and the 43 agricultural heritages in this area were used as samples,which have been included in Globally Important Agricultural Heritage Systems or Chinese Important Agricultural Heritage list.With the help of spatial analysis tool in ArcGIS 10.3 software,the spatial distribution characteristics of the agricultural heritage was evaluated using the nearest neighbor index,geographic concentration coefficient,concentration index,gathering zone analysis.The results shows that:(1)The distribution structure of the agricultural heritage in the four provinces of wuling mountain area is agglomerate shape,with significant spatial aggregation.(2)Spatial variance of agricultural cultural heritage was observed,which have one high concentration area and five secondary core circles,respectively in Tongren,Yichang,Enshi,Wuhan,Suizhou and Yongzhou,and each accumulation zone has a definite influence area.(3)The main factors affecting the spatial distribution of agricultural cultural heritage are specific location conditions,high quality ecological environment,abundant resource conditions and unique ethnic customs.In the future study,we should absorbs the theories and techniques from other social and humane studies like geography,economics,sociology,management and other disciplines to expand the depth and breadth of the research.
