Constructing ecological security patterns (ESP) effectively maintains ecosystems' green, healthy, and sustainable development. The InVEST model Conefor software were utilized in this study to pinpoint sources (eco-sources) through a blend of landscape connectivity the importance ecosystem services (IES); resistance surface was constructed by synthesizing gravity minimum cumulative (MCRM), extracted corridors (eco-corridors) nodes. Ultimately, research built ESP for Xinjiang. findings showed that: (1) 14 eco-sources identified Xinjiang, spanning an area 2.13 × 105 km2; 32 eco-corridors extracted, including 9 important 23 general eco-corridors, comprising total length 1.26 104 km; 46 nodes(eco-nodes); (2) size more patches Xinjiang 2.82 km2, which accounted relatively small size, value generally average. overall level primary high, but spatial distribution uneven; (3) values vary significantly, with high-level surfaces primarily located Junggar Basin Tarim low-level covering most Xinjiang's natural reserves other areas. study's can provide some references constructing at provincial scale arid semiarid regions planning restoration

Spatial vulnerability assessment of rural settlements in hilly areas using BP neural network algorithm

Ecological Indicators, Journal Year: 2023, Volume and Issue: 157, P. 111278 - 111278

Published: Nov. 24, 2023

Geological disasters occur frequently in hilly areas of Sichuan province, and the development rural settlement production life may be affected by geological disasters.This study aims to assess spatial vulnerability settlements Province through Back-propagation neural network, find main factors that really affect settlements, analyze distribution characteristics Province, methods reduce settlements. Through research, it can found three affecting are climate factors, soil erosion degree, hazard hidden danger degree. The quantitative factor data is ratio annual precipitation population settlements,the higher precipitation, vulnerability. second largest influencing degree erosion,the more severe erosion, districts counties. third major hazards, Other natural environment also have a certain impact on while socio-economic almost no Finally, relationship between its location obtained from relevant all sample counties, combined with Sichuan, summarized: closer counties fracture zone Longmen Mountain Longquan Mountain, settlements.The west than east, there little difference north south. Then, based above achievements, this proposes strategies suggestions providing reference materials support for local planning departments work.

Exploratory analysis of zero waste theory to examine consumer perceptions of sustainability: A covariance-based structural equation modeling (CB-SEM)

Cleaner Waste Systems, Journal Year: 2024, Volume and Issue: 8, P. 100146 - 100146

Published: March 30, 2024

The analysis of corporate and consumer sustainability practices is currently the focus several scientific disciplines due to their environmental impact diversity. This research aims create a hierarchy perceptions zero waste thinking that can guide government decisions regarding university communities' efforts. To achieve objectives this study, Hungarian citizens (students, faculty, staff) as potential consumers in Győr were involved purposive sampling approach. study adopted Covariance-Based Structural Equation Modeling (CB-SEM) methodology prove hypotheses related 7Rs Zero Waste citizens. rethink element was defined default condition for 7 R application therefore remained at top an endogenous variable. concluded it possible adapt business framework use, but only 5Rs be applied. conducted 90% confidence level, under which independent variables together explain 87% variance factor. results show four constructs, namely rot (β =0.12, ρ<0.1), reduce =0.21, recycle =0.26, ρ<0.05), reuse =0.43, ρ<0.05) significantly affect rethinking. Based on these regression weights, importance established.

Multidimensional spatial inequality in China and its relationship with economic growth

Humanities and Social Sciences Communications, Journal Year: 2024, Volume and Issue: 11(1)

Published: Oct. 24, 2024

Spatial inequality erodes social cohesion and political stability, impacting global sustainable development human well-being. This study examines spatial in China across economic, social, environmental, infrastructural, innovation dimensions, exploring how these inequalities evolve with economic development. Drawing on the Sustainable Development Goals Chinese planning goals, we selected 13 indicators pertinent to We employed population-weighted coefficient of variation, Gini coefficient, Moran's I assess analyzed their relationship growth. The findings reveal that currently exhibits highest lowest dimension. Since 1990, most have trended towards decreasing inequality, except for unemployment rates carbon emissions, which increased. gap between eastern coastal regions central western has widened, whereas disparities housing, healthcare, roads, digitalization narrowed. China's experience demonstrates Williamson's inverted U-shaped hypothesis extends beyond domain encompass education, infrastructure, digitalization, providing policy insights addressing regional post-pandemic era.

Published: May 18, 2024

Abstract This study focuses on the Yongqiao District in Suzhou City, Anhui Province, China, aiming to analyze current situation of ground settlement and its influencing factors area. The selected risk indices include rate, cumulative amount, groundwater level drop funnel, thickness loose sediment layer, soft soil number extraction layers. Additionally, vulnerability such as population density, building road traffic, functional zoning are considered. An evaluation index system for assessing land Subsidence was established. conducted using Hierarchical analysis-composite method ArcGIS spatial analysis, results show that area higher is about 2.82 km 2 , accounting 0.96% total area, mainly distributed Jiuli village, Sanba Street. middle around with an 9.18 3.13% lower areas were most covering 222.24 75.82% low assessment Bianhe Street part Zhuxianzhuang Town, 58.88 20.09% findings this not only crucial informing local policies practices related use planning, infrastructure development, emergency response but also enhance our understanding complexities processes their interactions human activities, future research practice environmental management.

Evaluation of Urban Sustainability through Perceived Importance, Performance, Satisfaction and Loyalty: An Integrated IPA–SEM-Based Modelling Approach

Sustainability, Journal Year: 2023, Volume and Issue: 15(12), P. 9788 - 9788

Published: June 19, 2023

In recent years, there has been a surge in research pertaining to sustainable urban development. Importance–performance analysis (IPA) emerged as one of the most widely used methods. However, few studies have combined IPA with structural equation modelling (SEM). This study introduces and evaluates an integrated IPA–SEM approach assess impact perceived importance performance city dimensions on residents’ satisfaction loyalty. The data for this were collected from 425 survey respondents residing Siliguri City West Bengal, India. results indicate that ‘Keep Up Good Work’ quadrant, consisting social quality, connectivity conditions, environmental significantly positively affected satisfaction. On other hand, ‘Concentrate Here’ quadrant concerning pollution presented negative yet insignificant relationship while both ‘Low Priority’ ‘Potential Overkill’ quadrants demonstrated no notable influence. Furthermore, robust positive correlation between loyalty is confirmed. Overall, findings offer valuable implications planning, policy-making, strategies aimed at enhancing quality life.
