摘要
研究重点脱贫地区“三生功能”协同与权衡和驱动力,是增强脱贫地区可持续发展能力,巩固深度贫困地区脱贫攻坚成果,有效衔接乡村振兴战略的重要依据。文章基于Spearman秩相关系数、Moran'sⅠ指数和地理探测器模型,选用2015-2020年土地利用类型和统计数据,分析重点脱贫地区脱贫前后“三生功能”协同与权衡关系时空演化特征和驱动力。结果表明:(1)2015-2020年,重点脱贫地区生产功能呈微弱下降趋势,其中西藏地区北部、青海藏区南部、四川藏区西部是主要低值区;生活功能提升明显,整体呈上升趋势,阿坝州部分地区功能值略微降低;生态功能略微提升,其中西藏地区北部和东南部,四川、云南藏区是主要高值区。(2)重点脱贫地区在时间上生产功能和生活功能的协同关系增强,而生产、生活功能与生态功能的权衡关系减弱,在空间上“三生功能”组合间权衡类区域减少,协同类区域增加,但权衡区域数量依旧高于协同区域数量,以权衡关系为主。(3)社会保障功能、生活服务功能与环境净化功能是影响重点脱贫地区“三生功能”协同与权衡时空变化的重要驱动力,生活类驱动与生态类驱动的交互组合影响作用大于单个因素作用。
Studying the synergies and trade-offs and driving forces of production-living-ecological function(PLEF)production-livingecological function(PLEF)in key poverty alleviation areas is an important basis for enhancing the sustainable development capacity of poverty alleviation areas,consolidating the poverty alleviation results in deeply impoverished areas,and effectively connecting with the rural revitalization strategy.Based on Spearman’s rank correlation coefficient,Moran’sⅠindex and geo-detector model,this study selects land use types and statistical data in 2015 and 2020 to explore the spatial and temporal evolution and driving force of the synergy and trade-off relationship of PLEF before and after poverty alleviation in key poverty-eradication areas.The results are as follows.(1)From 2015 to 2020,the production function of the key poverty alleviation areas declined slightly,with the northern part of Xizang,the southern part of Qinghai Tibetan area,and the western part of Sichuan Tibetan area being the main low-value areas;the life function improved obviously,with the overall rising trend,and the value of the function in some areas of Aba Prefecture was slightly reduced;the ecological function improved slightly,with the northern part and the southeastern part of Xizang,and the Tibetan area of Sichuan and Yunnan Province being the main high-value areas.(2)In time,the synergistic relationship between production and living functions in the key poverty alleviation areas has been strengthened,and the trade-off relationship between production,living functions and ecological functions has been weakened;spatially,the combination of PLEF has been reduced in the trade-off category,and the synergistic category has been increased;however,the number of trade-off areas is still higher than the number of synergistic areas,and the trade-off relationship is the main one.(3)The social security function,the living service function and the environmental purification function are the most important driving forces influencing the temporal and spatial changes of the synergy and trade-off among PLEF in the key poverty alleviation areas,and the interaction and combination of the living and ecological driving forces are more important than their individual roles.
