Land, Journal Year: 2024, Volume and Issue: 13(11), P. 1909 - 1909

Published: Nov. 14, 2024

The imbalance in the “production–living–ecology” function (PLEF) has become a major issue for global cities due to rapid advancement of urbanization and industrialization worldwide. realization PLEF coupling coordination is crucial region’s sustainable development. Existing research defined concept from perspective land measured its level using relevant models. However, there still room improvement indicator system, methods, other aspects. This work builds evaluation-index system based on human habitat multi-source data order examine spatial differences influencing factors Yellow River Basin (YRB). Using modified model, Moran index, Markov chain geographically weighted random forest model were introduced analyze temporal differentiation factors. results found that (a) YRB 2010 2022 been improving, number severely imbalanced reduced 23 15, but downstream cities’ significantly higher than upstream cities. probability maintaining their own greater 50%, basically no cross-level transfer. (b) index risen 0.137 0.229, which shows significant positive clustering phenomenon continually strengthening. intercity polarization effect being enhanced as seen LISA diagram. (c) There heterogeneity between time space. In terms importance level, series per capita disposable income (0.416) > nighttime lighting (0.370) local general public budget expenditure (0.332) beds 1000 people (0.191) NO2 content air (0.110). study systematically investigates dynamic evolution coupled mechanism, great practical use.

Spatial allocation and sustainable development: a study of production-living-ecological spaces in the Yangtze River Delta

Frontiers in Environmental Science, Journal Year: 2025, Volume and Issue: 12

Published: Jan. 9, 2025

The overlap and irrational distribution of Production-Living-Ecological Spaces (PLES) has disrupted traditional urban-rural development patterns impeded regional integration. This study, focusing on the Yangtze River Delta region, introduces a PLES framework constructs classification system based multitemporal land use data. CA-Markov model was employed to simulate changes for years 2030 2040. By quantifying analyzing number, distribution, transitions categories, study identifies spatial temporal evaluates coupling coordination various components. key findings are as follows: (1) proportion Production-Living Space (PLS) increased from 9 % in 2000 14 id="m2">% 2020, with projections indicating further growth 15 id="m3">% by both 2040, while Ecological (ES) remained relatively stable; (2) between stages evolved mild disharmony weak coordination, reflecting shift localized improvements broader, more integrated development; (3) exhibited significant heterogeneity, characterized higher values eastern lower western pattern concentration north dispersion southward. These contribute deeper understanding dynamics provide strategic recommendations optimizing layout urban agglomeration, thereby promoting sustainable development.

A Multi-Scenario Simulation and Driving Factor Analysis of Production–Living–Ecological Land in China’s Main Grain Producing Areas: A Case Study of the Huaihe River Eco-Economic Belt

Agriculture, Journal Year: 2025, Volume and Issue: 15(3), P. 349 - 349

Published: Feb. 6, 2025

The Huaihe River Eco-Economic Belt (HREEB) is a pivotal region in China’s national strategic planning. Land use this crucial to improving ecological quality and ensuring food security. Using the PLUS model Geodetector, we evaluated contribution interaction of 10 drivers production–living–ecological land (PLEL) performed multi-scenario simulations PLEL. results show that following: (1) Ecological mainly affected by elevation (contribution value > 0.16 for forest, grassland, water). Production influenced topographic relief, elevation, GDP per capita 0.13). Living driven capita, population density Interaction analysis shows nonlinear or two-factor enhancement among factors. (2) HREEB has relatively stable spatial pattern. Simulation indicate will not exceed 12% change next 50 years. (3) By 2075, under various scenarios predict significant changes area. Compared with natural development scenario, production increased 14.8% farmland protection living 14.3% urban scenario. This research vital managing developing PLEL resources within HREEB.

Evaluation and Influencing Factors of Coupling Coordination of “Production–Living–Ecological” Functions Based on Grid Scale: Empirical Experience of Karst Beibu Gulf in Southwest Guangxi, China

Land, Journal Year: 2025, Volume and Issue: 14(3), P. 614 - 614

Published: March 14, 2025

Territorial space (TS) is multifunctional, and exploring the relationships between functions their influencing factors key to achieving sustainable development of territorial space. However, existing research mostly focuses on exploration administrative units, while grid units needs be improved. This paper takes Beibu Gulf Economic Zone (BGEZ) in Guangxi as object, evaluates “Production–Living–Ecological” Functions (PLEFs) using land category scoring method summarizes evolution characteristics its spatial pattern. It analyzes dominant combined revealed comparative advantage index, explores various by introducing a coupling coordination degree model, comprehensively uses Geodetector Geographically Temporally Weighted Regression (GTWR) models analyze spatiotemporal heterogeneity functions. The results indicate that at scale (1) regional dominated ecological space, followed production with living accounting for smallest proportion. Production has decreased, increased, spaces flowing into (2) distribution relatively homogeneous, differentiation most significant. can divided three function-dominant types six function-combination types. (3) Living function primarily disordered functions, production–ecological mainly coordinated. (4) Policy regulation factor affecting functional coordination, scope influence each show significant heterogeneity. study reveals mechanisms temporal TS scale, providing scientific basis efficient use TS.

Published: Sept. 5, 2023

With the development of regional economy, metropolitan area has gradually shifted from rapid stage concentrating on central city to coordinated and integrated development. This trend brought new opportunities fringe area; however, due differences in resource endowment complex relationship between different levels government, inevitably contradictions imbalances economic social There been extensive research land use urban governance area, but less attention paid it is difficult quantitatively characterize interactions various forces this area. paper summarizes spatial pattern spatiotemporal characteristics construction Shenzhen based 30 m resolution cover dataset 2000 2020, analyzes driving factors affecting changes through logistic regression. The results show that overall study shifting cropland forest rural land. stages development, rate change varies greatly one period another. Three factors, population density, lighting index distance highway, have a significant correlation with built-up across region, while boundary effects administrative boundaries some variation impact expansion at levels. Finally, we put forward reducing negative divisions integration resources cities important for realizing synergistic
