Taking 14 prefecture-level cities in Guangxi as research object, this paper collects sorts out relevant data indicators them from 2007 to 2019, constructs evaluation index system, calculates by using comprehensive function, finally uses innovative digitization scheme further evaluate spatiotemporal coupling coordination relationship between following conclusions are ultimately drawn. First, level shows linear growth with unbalanced regional (values 0.306 0.598). Second, fluctuating obvious differences 0.264 0.483). Third, not synchronized, there mutual influence. Fourth, low (coupling values 0.369 0.513). Then, policy inspirations proposed. investment science technology innovation should be increased modern system. industrial structure optimized chain. construction infrastructure improved, high-quality agriculture promoted. education civilization strengthened, awareness environmental protection established. Fifth, they strengthen training cultivate new professional farmers. Sixth, improve utilization rate land enhance arable production capacity.

Regional Integration and Sustainable Development in the Yangtze River Delta, China: Towards a Conceptual Framework and Research Agenda

Land, Journal Year: 2023, Volume and Issue: 12(2), P. 470 - 470

Published: Feb. 14, 2023

Understanding the interactions between human sphere and natural in key places regions of world is crucial for promoting sustainability science achieving sustainable development. As one emerging global city-regions China Global South, Yangtze River Delta (YRD) plays an increasingly nonnegligible role globalized economy telecoupling social-ecological systems (SESs). Considering well-known importance representativeness, YRD has been regarded as appropriate experimental site integrated research on geographical at subnational scale. This paper tries to establish theoretical practical linkages regional integration development scale based goals (SDGs), Chinese contexts, a literature review relevant researches. We argue that future should pay more attention interdisciplinary, transregional, multi-scale attributes issues related YRD. The following agendas, such linking SDGs integrative development, analyzing SESs, assessing region scale, investigating different scales, exploring applicable governance structures institutions, well applying multi-source data interdisciplinary methodologies, call scholarly attention. hope this could be initial motion expand enrich research.

Understanding the Driving Factors for Urban Human Settlement Vitality at Street Level: A Case Study of Dalian, China

Land, Journal Year: 2022, Volume and Issue: 11(5), P. 646 - 646

Published: April 27, 2022

Vitality can effectively test the quality of regional space, put forward concept urban human settlement vitality, and explore development status vitality which is great significance in promoting high-quality settlements. By constructing an evaluation index system comprehensively using projection pursuit models, spatial correlation analysis, measurement pattern influencing factors settlements four districts Dalian were studied. The results are as follows: (1) differentiation characteristics remarkable. Overall, it gradually decreased from city center to administrative boundary. (2) dependence among regions relatively strong, with a more obvious “Matthew effect”. Among them, hot spots mainly distributed southeast Dalian, showing concentrated distribution trend, while cold northern fringe area homogeneity characteristics. (3) Topography, ecological environment, social economy, commercial development, structure, form, scale, etc. have different impacts on

Coupling coordination and spatio-temporal pattern evolution between ecological protection and high-quality development in the Yellow River Basin

Heliyon, Journal Year: 2023, Volume and Issue: 9(10), P. e21089 - e21089

Published: Oct. 1, 2023

The Yellow River Basin is one of the most important economic development belt and ecological management regions in China, it vital importance to study coupling coordination between protection high-quality development. However, systematic research from perspective ecological-production-living still lacking. Therefore, a comprehensive evaluation index system including 29 indicators constructed ecological, production living dimension. To evaluate level degree 61 cities Basin, measurement model are established using entropy weight TOPSIS method. With help ArcGIS, spatial characteristics visually illustrated. results showed that: (1) From 2011 2020, 61cities an increasing trend, upper lower reaches was higher than that middle reaches. (2) According cities, divided into three types: sustainable growth type with 44 fierce fluctuation 11 other 6 stable type. (3) ecology, also while not high. (4)About year-on-year rate for 2020 compared 2011, there 19 more 30 %, 23 20% 11cities 10%-20 8 less 10 %. (5) There significant difference does layout. different should adjust measures local conditions, give full play their advantages, make up shortcomings promote overall city.

Analysis of the Coupling Coordination and Spatial Difference Between Economic and Ecological Environment: A Case Study of China

Sustainability, Journal Year: 2025, Volume and Issue: 17(3), P. 869 - 869

Published: Jan. 22, 2025

This study adopts a sustainable development perspective to examine the economic and ecological coordinated progression spatial disparities across 30 regions in China from 2011 2022. Firstly, detailed analysis of CCD reveals that coordination between ES (economic subsystem) EES (ecological environment has been rising annually. However, overall level remains relatively limited. Second, kernel density estimation (KDE) shows degree various exhibits considerable variability, with disparity becoming increasingly pronounced. Third, trend surface (TS) indicates there exist regional variations EES. Specifically, east experiences an upward trend, while west downward trend. Similarly, south increase, whereas north demonstrates decrease. With ongoing development, it observed stable east–west direction; however, is increasing. Fourth, global Moran’s I pronounced positive autocorrelation. Finally, local Jiangsu, Fujian, Anhui, Jiangxi provinces exhibit significant high–high clusters, three Xinjiang, Gansu, Ningxia have always low–low clusters.

As an important means of reducing carbon emissions, environmental regulation and green technology innovation have become a top research topic in academia recent years. Existing studies investigated the phenomenon responses to but there is less existing literature explaining this from spatial perspective exploring effect joint mechanism emissions on innovation. Based econometric model, study used panel data 41 cities Yangtze River Delta urban agglomeration 2010 2019, measure impact interaction. The findings are as follows: shows trend “high east low west” has autocorrelation; responds positively changes regulations and, by decomposing effects, it can be observed that spillover surrounding areas; substitution between emissions. This paper combines above results proposes corresponding policy recommendations.
