中国村镇建设与资源环境耦合协调空间特征分析

The coupling coordination between the village and township development and its corresponding resources and environment in China

村镇建设与资源环境耦合协调是推进村镇可持续发展的客观要求。以中国县域为研究单元,构建评价指标体系并运用耦合协调度测算方法,探讨中国村镇建设与资源环境耦合协调空间格局与影响因素。结果表明,中国县域村镇建设得分介于0.07~0.81,高低分段区空间格局基本与地均GDP的高低相互对应。中国县域资源环境得分介于0.17~0.71,低分段区面积占比为32.12%,西北部大部分村镇资源环境需要得到重视。中国村镇建设与资源环境耦合协调度空间格局呈现东高西低;V5耦合协调度等级绝大部分分布在北京—北海一线以东的平坦地区;V4耦合协调度等级多数位于胡焕庸线以东,少部分位于天山周边;V2和V3耦合协调度等级区域主要分布在东北北部—西北—青藏高原的广大地区。V4耦合协调度等级的县数量占比最高。因此,基于中国村镇建设与资源环境空间格局,提出V4耦合协调度等级区域可着力建设农牧业特色产业集聚;V2和V3耦合协调度等级区域可加快推动少数民族特色的产业。

The coupling coordination between the village and township development and the corresponding resources and environment was the objective requirement for facilitating the sustainable development of villages and townships in China.An evaluation index system was proposed to examine the coupling coordination in China at county level.Furthermore,a coupling coordination degree model was employed to characterize the spatial pattern in the coupling coordination between the village and township development and the corresponding resources and environment and its driving factors.Results showed that the scores of the village and township development were between 0.07 and 0.81.The spatial patterns of the regions with high and low scores of the village and township development were similar with that of GDP per unit area.The scores of resources and environment were between 0.17 and 0.71.Those regions with low scores were 32.12%of the total area.Most villages and townships in Northwestern China deserved more attention for their low scores of resources and environment.The spatial pattern of the coupling coordination degree was high in the eastern part and low in the western part of China.Regions with V5 coordination degree level were mostly in the flat terrain to the east of Beijing–Beihai Line.Regions with V4 coordination degree level were mostly located at the east of the Hu Line and small parts located around the Tianshan Mountains.And regions with V2 and V3 coordination degree level were mainly distributed in the north of Northeast China–the Northwest China–the Qinghai and Tibet Plateau.The numbers of counties within V4 coupling coordination degree level accounted for the highest proportion.Therefore,the V4 region is more favorable to the industry cluster construction of agricultural and animal husbandry,based on the spatial patterns of the village and township development and the corresponding resources and environment.In the V2 and V3 regions,the industries with ethnic minority characteristics could be promoted.
