国土空间规划下全域土地综合整治与生态修复--以陇西县农业空间为例

Comprehensive Land Consolidation and Ecological Restoration in the Whole Region under Territorial Spatial Planning:A Case Study of Agricultural Space in Longxi County

开展农业空间土地综合整治能有效激活乡村人口、资本、技术等发展要素,能在破解土地细碎化难题、推进农业农村现代化进程和促进生态文明建设等方面发挥重要作用。本文选取甘肃省定西市陇西县第三次全国国土调查数据、统计年鉴、遥感影像等数据构建指标体系,科学评价陇西县农业空间耕地破碎度、农村居民点整治和宜耕后备资源开发潜力,以便在国土空间规划实施期间,对后期农业空间重点整治方向及重大项目落位提供借鉴。研究结果表明:陇西县耕地综合破碎度总体上呈现出东北高西南低的分布状态,中部破碎度最低,农村居民点整治潜力较大,重点整治潜力区有37个行政村,一般整治区有51个行政村,低整治区有92个行政村,无整治区有35个行政村;陇西县耕地后备资源地块数共计183块、1877.07公顷,宜耕后备资源开发潜力小且开发难度大。最后,依据评价结果,对各区域针对性地安排对应整治工程,着力构建“农田集中连片、建设用地集中集聚、空间形态高效集约”的新格局。

Carrying out the comprehensive agricultural space land consolidation can effectively activate the rural population,capital,technology and other development factors,and can play an important role in solving the problem of land fragmentation,promoting the process of agricultural and rural modernization and promoting the construction of ecological civilization.This paper selects the third national land survey data,statistical yearbook,remote sensing image and other data in Longxi County,Dingxi City,Gansu Province to construct an index system,and scientifically evaluates the fragmentation of agricultural space cultivated land,the rural residential areas consolidation and the development potential of arable reserve resources in Longxi County,so as to provide theoretical support for the key consolidation direction of agricultural space and the location of major projects in the later stage during the implementation of land space planning.The results show that the comprehensive fragmentation degree of cultivated land in Longxi County generally presents a distribution state of high in the northeast and low in the southwest,the fragmentation degree in the middle is the lowest,and the consolidation potential of rural residential areas is large.There are 37 administrative villages in the key consolidation potential area,51 administrative villages in the general consolidation area,92 administrative villages in the low consolidation area,and 35 administrative villages in the non-consolidation area.There are 183 plots of cultivated land reserve resources in Longxi County,with a total of 1877.07 hectares.The development potential of cultivated land reserve resources is small and the development is difficult.Finally,according to the evaluation results,the corresponding consolidation projects should be arranged for each region,and efforts should be made to build a new pattern of'centralized and contiguous farmland,centralized and concentrated construction land,and efficient and intensive spatial form'.
