Identifying the Spatial Range of the Pearl River Delta Urban Agglomeration from a Differentiated Perspective of Population Distribution and Population Mobility

Applied Sciences, Journal Year: 2025, Volume and Issue: 15(2), P. 945 - 945

Published: Jan. 18, 2025

Accurate identification of urban agglomeration spatial range is essential for scientific regional planning, optimal resource allocation, and sustainable development, forming the basis development policy. To improve accuracy identifying boundaries, this study fuses nighttime light data, which reflects economic levels, with LandScan data representing population distribution heatmap indicating mobility. This fusion allows from a differentiated perspective We propose new method dynamic boundaries agglomerations through multi-source fusion. not only provides technical support planning but also effectively guides functional positioning edge cities optimization allocation. The results show that identified by NTL_LS has an 80.37% kappa coefficient 0.5225, while NTL_HM achieves 89.17% 0.7342, level mobility more accurately in line real patterns. By adopting on mobility, we approach to range. research based provide comprehensive decision-making optimizing transportation layouts, allocating public resources rationally, defining cities.

Simulation and Attribution Analysis of Spatial–Temporal Variation in Carbon Storage in the Northern Slope Economic Belt of Tianshan Mountains, China

Land, Journal Year: 2024, Volume and Issue: 13(5), P. 608 - 608

Published: April 30, 2024

Intensive economic and human activities present challenges to the carbon storage capacity of terrestrial ecosystems, particularly in arid regions that are sensitive climate change ecologically fragile. Therefore, accurately estimating simulating future changes stocks on northern slope belt Tianshan Mountains (NSEBTM) holds great significance for maintaining ecosystem stability, achieving high-quality development belt, realizing goal “carbon neutrality” by 2050. This study examines spatiotemporal evolution characteristics NSEBTM from 1990 2050, utilizing a combination multi-source data integrating Patch-generating Land use Simulation (PLUS) Integrated Valuation Ecosystem Services Trade-offs (InVEST) models. Additionally, an attribution analysis stock is conducted leveraging land data. The findings demonstrate (1) predominantly consists underutilized land, accounting more than 60% total area NSEBTM. Unused grassland, water bodies exhibit declining trend over time, while other forms increasing trend. (2) Grassland serves as primary reservoir NSEBTM, with grassland degradation being leading cause loss amounting 102.35 t past three decades. (3) Under ecological conservation scenario 2050 compared natural scenario, there was net increase 12.34 t; however, under decrease 25.88 t. By quantitatively evaluating its impact projected next 30 years, this paper provides scientific references precise support territorial spatial decision making thereby facilitating achievement goals.

A system dynamics model based on ISM for risk perception in emergency by employees in chemical industrial parks

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: Oct. 28, 2024

Risk perception is one of the factors that guide human behavior in workplace. In accident prevention and emergency response, risk employees affects safety behaviour efficiency disposal. Besides, a complicated process restricted by many influencing factors. The study aims to identify most important affecting perception. This had three phases. first, were extracted based on questionnaire survey expert scoring. Then, Interpretive Structure Model (ISM) was used stratify 14 obtain hierarchical structure chart. Finally, analyzing influence paths ISM, system dynamics feedback loop diagram constructed. model took state variable "risk perception→ response→ identification→ communication→ perception" as main circular loop, supplemented perfected multiple feeder circuits. Research indicates experience fundamental factor aspect sensitivity analysis, shows related distance source. Its effectiveness quantifying qualitative data, identifying influential factors, establishing cause-effect relationships make it valuable tool for enhancing chemical industry park.
