基于宁夏西吉县 2020 年坡度、土地利用类型、人口等数据,采用GIS空间分析法及定性与定量分析相结合的方法对西吉县区域开发敏感度进行了评价,将该县划分为 1 个低敏感区域、6 个中敏感区域、6 个较高敏感区域和 6 个高敏感区域,并且依据敏感区域分区特点总结了区域开发敏感度空间分布规律.结果表明:西吉县开发中敏感区域和高敏感区域分别占研究区总面积的 34%和 30%,较高敏感区域占 28%,低敏感区域占 8%;从区域分布情况来看,西吉县呈现"中部高四周低"及"西高东低"的地形分布特征,其中中敏感区域主要分布在该县东南部,高敏感区域在北部、西部、南部均有分布,较高敏感区域主要分布在西南部,低敏感区域集中分布在中心地带.研究结果客观地反映了西吉县的开发敏感状况,能够为该县的生态保护、资源利用和可持续发展提供参考.
Study on the Regional Development Sensitivity of Xiji County
Drawing upon 2020 data on slope,land use types,and population in Xiji County,Ningxia,this study evaluated the county's regional development sensitivity using GIS spatial analysis along with a combination of qualitative and quantitative approaches.The county was categorized into one low sensitivity area,six medium sensitivity areas,six relatively high sensitivity areas,and six high sensitivity areas.Furthermore,the study synthesized the spatial differentiation rules of regional development sensitivity based on the characteristics of the sensitive areas.The results reveal that the medium and high sensitivity areas of Xiji County constitute 34%and 30%of the total study area,respectively,with the relatively high sensitivity areas accounting for 28%,and the low sensitivity areas making up 8%.Geographically,the county exhibits a pattern of"high in the middle,low in the surrounding areas"and"high in the west,low in the east".Specifically,the medium sensitivity areas are predominantly situated in the southeastern part of the county,while the high sensitivity areas are distributed in the north,west,and south.The relatively high sensitivity areas are mainly in the southwest,and the low sensitivity areas are concentrated in the central region.The findings objectively reflect the development sensitivity status of Xiji County and can provide a reference for the county's ecological conservation,resource utilization,and sustainable development strategies.
