摘要
以塔里木河流域为研究区,构建流域范围内5个地州的农用地和建设用地土地利用效率评价指标体系,基于数据包络分析(DEA)模型估算塔里木河流域土地开发与利用效率,并研究1990—2020年农用地、建设用地土地利用效率和综合土地利用效率时空变化特征。结果表明:2020年塔里木河土地利用综合效率为0.92,农用地土地利用效率为0.84,建设用地土地利用效率为1.00;1990—2020年土地利用综合效率呈现稳步上升的趋势,从0.41上升至0.92;农用地土地利用效率呈现波动上升趋势,从0.52上升至0.84;建设用地土地利用效率呈现显著上升的趋势,从0.30上升至1.00。总体来看,塔里木河流域土地利用效率发展整体为上升趋势,土地利用综合效率高值分布在2013—2020年,低值分布在1990—2000年,各地州土地利用效率变化存在明显差异,表明塔里木河流域用地效率明显提升,但区域间发展不平衡。
This study took the Tarim River Basin as the research area and constructed an evaluation index system for the utilization efficiency of agricultural and construction land in five prefectures within the basin.Based on the data envelopment analysis(DEA)model,the efficiency of land development and utilization in the Tarim River Basin was estimated,and the spatiotemporal changes in the utilization efficiency and comprehensive utilization efficiency of agricultural and construction land from 1990 to 2020 were explored.The comprehensive efficiency of land use in the Tarim River in 2020 was 0.92,the efficiency of agricultural land use was 0.84,and the efficiency of construction land use was 1.00;from 1990 to 2020,the comprehensive efficiency of land use showed a steady upward trend,rising from 0.41 to 0.92;the efficiency of agricultur-al land use showed a fluctuating upward trend,rising from 0.52 to 0.84;the land use efficiency of construction land showed a significant upward trend,rising from 0.30 to 1.00.The overall development of land use efficiency in the Tarim River Basin was on the rise,with high values of com-prehensive land use efficiency distributed from 2013 to 2020 and low values distributed from 1990 to 2000.There were significant differences in changes in land use efficiency among different states,indicating a significant improvement in land use efficiency in the Tarim River Basin,but uneven development between regions.
