摘要:

河西走廊是我国人类活动最密集的干旱地区,明晰河西走廊国土空间格局演变特征及驱动机制有助于缓解地区国土空间开发保护矛盾。采用空间转换矩阵、景观格局指数、最优参数地理探测器等方法,从“量变”“形变”2个维度定量研究2000—2020年河西走廊国土空间格局时空演变特征及其驱动力。结果表明:(1) 河西走廊城镇空间、农业空间以及其他生态空间持续扩张,绿色生态空间剧烈减少了2758.87 km2,国土空间开发程度不断提高的同时生态保护效果尚不显著。(2) 国土空间主导转换类型是生态空间内部“荒漠-绿地”交互演变,不同主体功能区中交叉转换规模差异显著。伴随国土空间交叉转换,其景观格局呈现出破碎化、分散化、复杂化演变特征。(3) 河西走廊国土空间格局演变受到多维度影响因子驱动,其中“量变”过程受到的驱动作用包括国家政策指引、自然地理支撑、交通区位约束和社会经济催化,而“形变”则是以自然地理为基础,在交通区位和社会经济的影响下进一步发生演化。

Abstract:

The Hexi Corridor, as China’s most densely populated arid region, necessitates a thorough understanding of the evolution of its spatial patterns and the underlying driving mechanisms to reconcile regional development with environmental protection within a three-zone framework. This research employs a suite of quantitative methods, including the spatial transition matrix, landscape pattern index, and optimal parameter geographical detector, to examine the spatiotemporal characteristics and determinants of territorial spatial pattern changes in the Hexi Corridor from 2000 to 2020, focusing on “quantitative change” and “form change”. The findings reveal as follows: (1) The Hexi Corridor’s urban, agricultural, and various ecological spaces have expanded, accompanied by a notable decline of 2758.87 km2 in green ecological areas. Despite heightened developmental activities across the three-zone space, ecological conservation efforts have yet to yield significant results. (2) The predominant form of territorial space transition is the internal “desert-green land” dynamics within ecological zones, marked by considerable variability in the extent of cross-transformation across different functionally oriented zones. This cross-transformation of territorial spaces is characterized by increasing fragmentation, dispersion, and complexity in landscape patterns. (3) The territorial spatial pattern evolution in the Hexi Corridor is influenced by multifaceted factors. “Quantitative change” is primarily driven by national policy directives, natural geographic conditions, transportation-related constraints, and socio-economic drivers, whereas “form change” is shaped by natural geography and further modified by transportation and socio-economic factors.
