摘要
科学认知青藏高原水生态空间时空演化过程与驱动因素,是筑牢“亚洲水塔”和实现地区“人―水资源―生态”协调可持续发展的迫切需求。采用空间转换矩阵和地理探测器等方法研究了2000―2020年青藏高原水生态空间的演化特征与驱动机制,结果表明:①近20年青藏高原水生态空间规模不断增加,增幅达21.53%,横断山西北侧,位于西藏、青海、四川和云南4省交汇处的“青海省果洛州达日县―西藏自治区林芝市察隅县”一线两侧地区增幅最为显著;②其他生态空间向水生态空间的转化是主导变化类型,气候变暖和人为活动影响使冰川和积雪蓄水流向河流湖泊,使青藏高原水资源呈“液态化”且水生态空间向东蔓延;③青藏高原地区水生态空间的演化受政策工程、自然地理、交通区位和社会经济等多方面因子的共同驱动,各类型因子整体呈现出非线性增强的交互驱动作用,其中自然地理类和交通区位类因子的作用强度q值平均水平远大于其他因子,是青藏高原水生态空间演化的主导驱动因素。
A scientific understanding of the spatio-temporal evolution process and driving factors of water ecological space in the Tibetan Plateau is an urgent requirement to build the“Asian water tower”and establish the coordinated and sustainable development of human-water resources-ecology in the region.In this study,a spatial transformation matrix,spatial correlation analysis,and geographical detector were used to determine the evolutionary characteristics and driving mechanisms of the aquatic ecological space in the Tibetan Plateau from 2000–2020.The following results were obtained:①During the past 20 years,the aquatic ecological space in the Tibetan Plateau has increased by 21.53%.The northwest side of the Hengduan Mountains,the intersection of Tibet and the Qinghai,Sichuan,and Yunnan provinces,“Dari County,Guoluo Prefecture,Qinghai Province-Chayu County,Linzhi City,Tibet Autonomous Region,”had the most significant increase.②The transformation from other ecological space to water ecological space is the dominant change type,and climate warming and human influence have caused glaciers and snowmelt to flow into rivers and lakes.Therefore,water resources in the Tibetan Plateau have melted and water ecological space have been extended eastward.③The evolution of water ecological space in the Tibetan Plateau is jointly driven by many factors,such as policy engineering,natural geography,traffic location,and social economy.Each type of factor had a nonlinearly enhanced interactive driving effect as a whole;this caused the average value of the action intensity q of natural geography and traffic location to be far greater than that of other factors,which is the dominant driving factor for the evolution of the water ecological space in the Tibetan Plateau.
