Abstract:

It is known that the ecological vulnerability is rather prominent in the Yellow River Basin (YRB); there are great differences in economic development mode between resource-based and non-resource-based cities in this basin. Studying the evolution and regional differences of the production-living-ecological space (PLES) of two types of cities in the basin, which is particularly important to understand the development and utilization of land-space in the YRB. Based on the PLES classification, this study measured the regional differences of PLES in the two types of cities by employing spatial auto-correlation and Theil index. It was found that: (1) PLES of the two types of cities changed dramatically, living space had increased significantly; the ecological space of resource-based cities was squeezed by living and production space for a longer time; while the production space of non-resource-based cities was squeezed by living and ecological space for a longer time. (2) PLES of the two types of cities showed the characteristics of spatial aggregation, and the high-density area and low-density area of PLES of each type was relatively stable. (3) For factors (economy and population) affecting the regional difference of PLES of the two types of cities, economic development was more likely to cause the change of PLES. Influenced by economic development and population, the regional difference of the PLES of non-resource-based cities was obvious, while that of resource-based cities was comparatively small. Possible reasons for the differences may be the diverse modes of economic development in non-resource-based cities and the lack of diversity in resource-based cities. The overall regional differences of PLES of all cities in the Yellow River Basin mainly depend on the internal differences of the two types of cities. The regional differences of production and ecological spaces from the resource-based cities and the regional differences of living space from the non-resource-based cities had major impact on the regional differences of PLES of all cities in the Yellow River Basin. This paper puts forward relevant countermeasures and suggestions, which is of significance for the management of land-space in the YRB.

Key words: Yellow River Basin, production-living-ecological space (PLES), regional differences, resource-based cities, non-resource-based cities
