长江经济带乡村功能区域差异及类型划分

Regional differences and types of rural functions in the Yangtze River Economic Belt

深度挖掘乡村功能价值是实现乡村全面振兴的重要途径,论文通过构建乡村功能综合评价指标体系,运用GIS和泰尔指数,揭示了2016年长江经济带130个市(区)乡村"生产-生活-生态"功能地区差异特征和差异来源,并进行功能分区。研究结果显示:①长江经济带乡村功能具有显著的空间分异特征,农业生产功能强的区域集中在中游和下游平原地区;人居生活功能强的区域集中在下游省会及核心发展城市周边;生态保育功能强的区域在上游和中游山地丘陵地区。②乡村功能总体区域差异来源于上、中、下游地区内部差异,农业生产功能在上游内部区域差异显著,人居生活功能和生态保育功能在下游内部区域差异显著,中游地区乡村功能整体区域差异较小。③基于研究结果将研究区划分农业生产区、人居生活区、生态保育区、人居生活-农业生产复合区、人居生活-生态保育复合区、生态保育-农业生产复合区、农业生产-人居生活-生态保育综合发展区和农业生产-人居生活-生态保育综合协调区8种功能类型区,可为完善长江经济带乡村功能的空间布局提供科学依据。

Making use of the advantages of different rural functions is an important way to realize rural revitalization.By constructing an index system of rural function evaluation and using GIS and the Theil index,the characteristics of production-living-ecological functions and source of regional differences in rural areas in the Yangtze River Economic Belt in 2016 were revealed.The results show that:1)The spatial differentiation of production-living-ecological functions in rural areas of the Yangtze River Economic Belt was obvious.Midstream and downstream plain areas have a strong agricultural production function,downstream provincial capital cities and core development cities have powerful living function,and upstream and midstream mountainous and hilly areas have a strong ecological conservation function.2)The overall regional differences in rural functions are derived from intraregional differences.The agricultural production function is significantly different within the upstream region,and the life and ecological conservation function is significantly different within the downstream region.The overall differences in rural functions in the midstream area are not significant.3)Based on the evaluation results,the study area is divided into eight types of functional areas,namely,agricultural production area,living area,ecological conservation area,living-agricultural production area,living-ecological conservation area,agricultural production-ecological conservation area,agricultural production-living-ecological conservation development area,agricultural production-living-ecological conservation coordination area,thus providing a scientific basis for improving the spatial layout of rural functions in the Yangtze River Economic Belt.
