Abstract:

To clarify the laws and evolution characteristics of territorial spatial differentiation is the basis and premise for improving governance capacity and building a balanced development pattern of territorial spatial pattern. Based on the theory of production-living-ecological spaces, the land use data from 1995 to 2020 are used to analyze the characteristics of the territorial spatial evolution characteristics of Lanzhou-Xining urban agglomeration by using the methods of land spatial transfer matrix, standard deviation ellipse, nuclear density analysis, comparative advantage index. The results show that: (1) The horizontal regional difference and vertical gradient differentiation of territorial space are obvious in the Lanzhou-Xining urban agglomeration. The ecological space occupied the absolute dominant position, and the production and living spaces are together in the medium altitude of Lanzhou-Xining urban agglomeration; (2) The territorial spatial conversion speed of Lanzhou-Xining urban agglomeration is accelerated, and the largest conversion proportion comes from the production space to living space, which indicates that the interaction between the two types of spaces is obvious. The downtown areas of Lanzhou and Xining, Lanzhou New Area and Linxia city are the conversion hotspot; (3) The production space and living space are distributed from northwest to southeast, and the ecological space is evenly distributed from east to west. The distribution patterns and expansion mode of production-living-ecological spaces are quite different. The shift distance of the gravity center of the living space is the largest, the production space is multi-core diffusion, and the fragmentation trend of the ecological space is enhanced. From the scale of towns, six types of optimal zoning of territorial space are identified, and zoning guidance strategies are proposed to promote the balanced and coordinated development of territorial space in Lanzhou-Xining urban agglomeration.

Key words: territorial spatial pattern, production-living-ecological spaces, zoning optimization, Lanzhou-Xining urban agglomeration, upper reaches of the Yellow River
