摘要
基于"压力—状态—响应(Press-State-Response,PSR)"评估框架,以太行山区1990—2015年的土地利用数据和经济社会统计资料为数据源,选取14个指标构建了土地利用冲突强度诊断的综合评价模型,对太行山区的土地利用冲突强度进行了定量测度,并运用探索性空间数据分析方法(Exploratory Spatial Data Analysis,ESDA),对各县级行政单元土地利用冲突强度的时空演化特征进行了探讨。结果表明:太行山区的土地利用冲突强度有所缓解,综合指数由0. 219降到0. 166;压力指数、状态指数、响应指数和综合指数的Global Moran's I值分别为0. 3059、0. 1739、0. 0969、0. 2811,压力指数空间集聚特征显著,响应指数空间集聚性较小;土地利用冲突综合指数的热点区、次热区则趋于向京津冀地区迁移,冷点区、次冷区趋于向山西省广大区域转移。
Based on the"Press-State-Response( PSR) "evaluation framework,the land-use data and social-economic statistics of the Taihang Mountains areas from 1990 to 2015 were used as data sources,and 14 indicators were selected to construct the land-use conflict intensity diagnosis comprehensive evaluation model to quantitatively measure the intensity of land-use conflict in Taihang Mountainous areas,and explored the spatial-temporal evolution characteristics of land-use conflict intensity of county-level administrative units using Exploratory Spatial Data Analysis( ESDA). The results showed: From 1990 to 2015,the intensity of land-use conflict in Taihang Mountainous Areas was alleviated because LUCI( Land Use Conflict Index) dropped from 0. 219 to 0. 166. The Global Moran's I values of press index,state index,response index and LUCI were 0. 3059,0. 1739,0. 0969 and 0. 2811,the spatial agglomeration characteristics of press index was significant,and the response index spatial agglomeration was small. The hotspots and sub-hot zones of the LUCI tended to migrate to the Beijing-Tianjin-Hebei region,and the cold-spot and sub-cold regions tended to shift to the vast areas of Shanxi Province.
