摘要
乡村多功能时空演变特征与影响因素研究为有效破解城乡二元结构、推动城乡融合发展的提供重要科学依据。本文以长株潭地区23个县市区作为研究对象,综合运用熵值法、地理探测器等方法分析长株潭地区乡村多功能时空演变特征与影响因素。结果表明:(1)2010~2020年长株潭地区乡村生产功能空间格局变化差异较小,大体上保持中间高四周低的态势,中心市辖区比四周地区的乡村生产功能高;乡村生活功能空间格局变化较大,整体呈下降趋势,降幅较大的有望城区、长沙县、岳麓区等区县,Ⅰ级区、Ⅱ级区范围逐渐缩小至开福区、天心区、雨花区、芙蓉区、雨湖区、荷塘区、芦淞区等区;乡村生态功能大体上保持西低东高的空间分布格局,属于Ⅰ级区的县域单元增加了开福区和韶山市,Ⅱ级区减少了2个,Ⅲ级区的县市区个数保持不变。(2)长株潭地区乡村多功能分异的主要影响因素是人均GDP、有效灌溉面积比例、农村劳动力总数、城镇化率,影响因子呈现多元化特征。
The research on the spatiotemporal evolution characteristics and influencing factors of rural multi-function is an important scientific basis for effectively solving the urban-rural dual structure and promoting the urban-rural integration development.This paper takes 23 counties and cities in Changsha-Zhuzhou-Xiangtan area as the research object,and comprehensively uses entropy method,geographic detector and other methods to analyze the spatiotemporal evolution characteristics and influencing factors of rural multi-function in Changsha-Zhuzhou-Xiangtan area.The results show that:(l)The spatial pattern of rural production functions in Changsha-Zhuzhou-Xiangtan area has a small difference from 2010 to 2020,and generally maintains a trend of high in the middle and low in the four areas.The rural production functions in the central city area are higher than those in the surrounding areas;The spatial pattern of rural living functions has changed greatly,showing a downward trend on the whole,Wangcheng district,Changsha county,Yuelu district etc.with a large decline.The scope of Class Ⅰ and Class Ⅱ districts has been gradually reduced to Kaifu District,Tianxin District,Yuhua District,Furong District in Changsha,Yuhu District,Hetang District in Xiangtan,Lusong District in Zhuzhou and other counties and cities with a largo decline;The rural ecological functions generally maintain the spatial distribution pattern of low in the west and high in the east.Kaifu District and Shaoshan City have been increased in the county units belonging to the Class Ⅰ area,while the number of Class Ⅱ areas has been reduced by 2,and the number of counties and cities in the Class Ⅲ area has remained unchanged.(2)The main influencing factors of rural multi-function differentiation in Changsha-Zhuzhou-Xiangtan area are GDP per capita,the proportion of effective irrigation area,the total number of rural labor force,and the urbanization rate.The influencing factors are diversified.
