Evolution Characteristics and Its Driving factors of Production–Living–Ecological Space in typical hilly areas: A Case Study of Changshou District in China from 2000 to 2020

Abstract

In the context of sustainable territorial spatial development, the ecological functions of hilly areas are emphasized, and clarifying the evolutionary characteristics and drivers of production-living-ecology space (PLES) in hilly areas is important for optimizing regional development patterns and promoting environmental quality development. In this study, the current land use status and topographic data of typical hilly areas in southwest China (Changshou District, Chongqing) in 2000, 2010, and 2020 were selected, and the evolution characteristics of PLES and its driving factors were systematically studied by using land use transfer matrix, landscape index and geodetector. The results show that. (1) PLES shows a pattern of one decrease and two increases (production space decreasing year by year, living and ecology space increasing). (2) under the influence of hilly topography, the vertical variation of PLES is obvious with the threshold of 450m in elevation and 9° in slope. (3) PLES landscape diversity increases, dominance increases, and fragmentation increases. (4) Natural conditions, transportation location and socio-economics are important driving factors affecting the evolution of PLES patterns.
