Research investigates the transformations in production–living–ecological spaces (PLES) across diverse scenarios and their ecological effects, with aim of offering advice for environmental preservation long-term growth Sichuan Province. Utilizing PLUS model, we simulated PLES configuration Province year 2030 subsequently evaluated its impacts using an effect assessment model. The findings reveal that: (1) population GDP are key drivers expansion Industrial-Production Spaces (IMPS), Urban-Living (ULS), Rural-Living (RLS), whereas altitude has a crucial influence on shaping Agricultural-Production (APS), Forest-Ecological (FES), Grassland-Ecological (GES), Water-Ecological (WES), Other-Ecological (OES); (2) significant changes observed by four scenarios, notable distinctions between production priority scenario other three; (3) variations quality exist among concerning PLES; (4) reasons behind better or worse conditions differ scenarios. research demonstrates that model can effectively simulate under multiple 2030, various potential development pathways corresponding thereby aiding selection optimal pathways.

Ecological Zoning Study on the Coupling of Land Use Intensity and Landscape Ecological Risk in Western Jilin: A Production–Living–Ecological Space Perspective

Sustainability, Journal Year: 2024, Volume and Issue: 16(24), P. 10992 - 10992

Published: Dec. 14, 2024

Ecological zoning is essential for optimizing regional ecological management and improving environmental protection efficiency. While previous studies have primarily focused on the independent analysis of land use intensity (LUI) landscape risk (LER), there has been limited research their coupled relationship. This study, conducted in Western Jilin (WJL), introduces an innovative method based Production–Living–Ecological Space (PLES) framework, which explores interactions between LUI LER, filling a gap existing research. The employs coupling coordination degree (CCD) model Geographic Information System (GIS) technology to construct LUI-ERI model, used delineate zones. results indicate that: (1) PLES study area predominantly production space (PS), with largest transfer being (PES) 2784.23 km2, most significant PS 3112.33 km2. (2) Between 2000 2020, both LER exhibited downward trends, opposite spatial distribution characteristics. “middle” zone “highest” were dominant types, covering approximately 46% 45% total area, respectively. (3) showed polarized trend, overall upward trajectory from 2020. (4) WJL can be categorized into core (ECP) zone, potential governance (EPG) comprehensive monitoring (ECM) optimization (EO) restoration (ER) occupying 61.63% area. provides novel perspective offers systematic scientific basis planning.

Dynamics of Territorial Spatial Pattern and Landscape Impact under Different Economic Gradients: A Case Study of the Beijing-Tianjin-Hebei (BTH) Region, China

Sustainability, Journal Year: 2022, Volume and Issue: 15(1), P. 259 - 259

Published: Dec. 23, 2022

This study analyzes territorial spatial pattern changes and landscape under different economic development gradients in 1980, 1990, 2000, 2010 2018 the Beijing-Tianjin-Hebei (BTH) region of China. Then it discusses relationship between area patterns. The results indicate that: (1) for middle- low-development regions are characterized by “continuous shrinkage agricultural space, continuous expansion urban a decrease followed an increase ecological space”; (2) higher level regional development, more severe change national territory; (3) common trend structural transformation is obvious flow production space into rural living space—the difference that outflow than inflow, while opposite holds true medium- high-development regions; (4) fragmentation degree increasing, decreasing. With spread diversity decreases increases, respectively. correlation metrics shows distinct differences.

Land Use Transformation Based on Production-Living-Ecological Space and Associated Eco-Environment Effects: Evidence from the Upper Reaches of the Yangtze River, China

Research Square (Research Square), Journal Year: 2023, Volume and Issue: unknown

Published: June 10, 2023

Abstract The rapid process of urbanization and industrialization has intensified the competition among various stakeholders for land resources, leading to increasingly fierce mutual conversion between production, living ecological land, thus causing fluctuations in regional environmental quality. This study focuses on upper reaches Yangtze River (URYR), use data were obtained by interpreting five remotely-sensed images taken 1980, 1990, 2000, 2010, 2020. Using methods such as transfer matrix, quality index, geographic detector etc., conducts quantitative analysis transformation, eco-environmental effects, influencing factors URYR. results show that from 1980 2020, transformation is manifested an increase a decrease production land. primary type space evolution overall eco-environment declined. high-value areas are mostly concentrated southwest east, while low-value aggregation formed central western parts. Natural environment serve base influence strong weak topographic relief, slope, net productivity (NPP), mean annual temperature, altitude, intensity, economic density, average precipitation, road network population density diversity. research findings presented this paper can valuable reference fields conservation territorial spatial planning.
