摘　　要：在国土空间规划体系构建与生态文明建设的战略交汇期,现有研究对地形复杂、生态脆弱且经济高速发展的长江经济带上游地区的国土空间格局演化缺乏关注。分析长江经济带上游地区329个县区级行政单元在2010~2019年土地利用结构和“三区空间”的时空演化特征,从人地关系视角探究演化的驱动机制,为优化国土空间格局、统筹生态保护和经济发展,实现高效可持续发展提供经验参考。结果表明:(1)近10年,长江经济带上游地区城镇空间持续扩张,分别占用2191.25 km^(2)农业空间和413.19 km^(2)生态空间,4223.89 km^(2)农业空间转为生态空间。(2)2010~2015年,以农业空间转城镇空间为主导,主要分布在成渝、黔中和滇中城市群地区;2015~2019年,以农业空间转生态空间为主导,主要分布在云贵高原东侧山区。(3)“三区空间”交叉转换受到客观承载环境(地)、人类发展活动(人)以及两者的交互影响,体现为人类社会发展的空间需求,受土地使用的价值观与社会客观运行规律约束,在自然环境现状承载与发展适宜性格局的基础上,驱动“三区空间”演化。In the strategic intersection period of land spatial planning system construction and ecological inquiry construction,the existing research lacks attention to the evolution of land spatial pattern in the upper reaches of the Yangtze River Economic Belt with complex terrain,fragile ecology and rapid economic development.This paper analyzes the spatial and temporal evolution characteristics of land use structure and“three-zone space”of 329 county-level administrative units in the upper reaches of the Yangtze River Economic Belt from 2010 to 2019,and explores the driving mechanism of evolution from the perspective of human-land relationship,so as to provide experience reference for optimizing land spatial pattern,coordinating ecological protection and economic development,and realizing efficient and sustainable development.The results show that:(1)In the past 10 years,the urban space in the upper reaches of the Yangtze River Economic Belt has continued to expand,occupying 2191.25 km^(2) agricultural space and 413.19 km^(2) ecological space,and 4223.89 km^(2) agricultural space has been converted to ecological space.(2)From 2010 to 2015,dominated by agricultural space to urban space,mainly distributed in Chengdu-Chongqing,central Guizhou,and central Yunnan urban agglomeration areas;from 2015 to 2019,dominated by agricultural space to ecological space,mainly distributed in the eastern mountainous area of Yunnan-Guizhou Plateau.(3)The cross-transformation of the“three-zone space”is affected by the objective carrying environment(land),human development activities(man)and the interaction between the two,which is reflected in the spatial demand of human social development.Restricted by the values of land use and the objective operation law of society,the evolution of the“three-zone space”is driven based on the current situation of natural environment carrying and the development suitability pattern.
