湖南武陵山片区地域功能演变及影响因素识别

Evolution of regional functional and identification of influencing factors in Wuling mountain area of Hunan Province

针对乡村传统功能退化、功能混杂、人地矛盾加剧等问题,该文运用ArcGIS空间分析等方法对湖南武陵山片区乡村功能的时空格局演变进行了分析探讨。通过构建乡村地域多功能评价指标体系,对乡村各项功能的时间变化和空间分异进行可视化分析,并结合地理探测器进行影响因素识别。研究结果表明:2008—2018年湖南武陵山片区乡村各项功能指数随时间变化整体均呈现上升的趋势;2008—2018年湖南武陵山片区农业生产功能和生活保障功能的冷热点分布区重合度较高,热点区集中分布在研究区域的东南部,冷点区主要位于研究区的西部;社会经济因素是影响多功能空间分异的主要因素,地区生产总值、第一产业产值居于主导地位。

In view of the degradation of traditional rural functions,mixed functions,and the intensification of the contradiction between people and land,this paper used ArcGIS Spatial analysis and other methods to analyze and discuss the evolution of the spatial and temporal pattern of rural functions in Wuling Mountain area,Hunan Province.By constructing the multi-functional evaluation index system for rural areas,visual analysis was conducted on the temporal and spatial differences of various functions in rural areas,and influencing factors were identified using geographic detectors.The research results mainly showed that(1)the overall trend of each function index of rural villages in the Wuling Mountain area of Hunan Province from 2008 to 2018 showed an increase over time.(2)The cold and hot spot distribution areas of agricultural production function and life security function in the Wuling Mountain area of Hunan Province from 2008 to 2018 overlapped well,with the hot spot areas concentrated in the southeastern part of the study area and the cold spot areas mainly located in the western part of the study area.(3)Socio-economic factors were the main factors affecting the multifunctional spatial differentiation,with gross regional product and primary industry output dominating.
