Under the influence of factors such as extreme weather and accelerated urbanization, China has witnessed a sharp escalation in conflicts between various land-use functions, leading to significant rise tensions people land. The coordination production, living, ecological functions is particularly important for strengthening civilization achieving regional high-quality development. concept “Production–Living–Ecological” (PLE) Spaces, proposed part China’s initiative, refers spatial framework that integrates production spaces (land agriculture, industry, commerce), living housing, consumption, public services), supporting ecosystem regulation biodiversity). Based on this perspective, paper investigates current situation potential function Guangdong–Hong Kong–Macao Greater Bay Area 2020. Utilizing multi-criteria evaluation analysis method, study develops function-evaluation model. Furthermore, establishes diagnostic model intensity based different permutations combinations land unit intensities. are categorized into ten types four stages. main findings follows: (1) In 2020, overall Guangdong, Hong Kong, Macao were at high, medium-high, low levels, respectively. stable controllable stage, largely out-of-control severely stage accounted 39.22%, 28.73%, 25.41%, 6.64%. focal points mainly located Guangzhou, Foshan, Shenzhen, Dongguan. (2) area was exposed varying degrees risk from conflicts, proportion conflict area, with proportions low, general, higher, high-conflict-potential areas being 47.88%, 23.43%, 22.14%, 6.54%, (3) primary hotspots concentrated Dongguan City administrative border “Foshan–Zhaoqing”, “Foshan–Jiangmen”, “Guangzhou–Zhongshan”.

Research on the geometric weighting-coupling degree method for the urban ecological environment vulnerability index

Ecological Indicators, Год журнала: 2024, Номер 162, С. 112023 - 112023

Опубликована: Апрель 17, 2024

Constructing a scientifically effective Urban Ecological Environment Vulnerability Index provides solid foundation for accurately describing the evolution of urban ecological environment vulnerability and making precise predictions about its risks. The existing composite index methods emphasize strength relationships among influencing factors but overlook synergistic interactions between dimensions. Given this, this article constructed system based on theoretical models sensitivity, resilience, pressure (SRP). We used geometric weighting method to describe strong weak introduced coupling model from physics portray coordination relationship Finally, we proposed constructing weighting-coupling degree method. data 35 cities in China as baseline validate stability reliability results indicated that compared with other major synthesis methods, trend peaks troughs average values indices synthesized by is smoother, which more consistent vulnerability. stage governance This validated better weighted-coupling researchers depict It may be methodological reference managers govern environment.

A Satellite View of the Wetland Transformation Path and Associated Drivers in the Greater Bay Area of China during the Past Four Decades

Remote Sensing, Год журнала: 2024, Номер 16(6), С. 1047 - 1047

Опубликована: Март 15, 2024

As a highly productive and biologically diverse ecosystem, wetlands provide unique habitat for wide array of plant animal species. Owing to the strong disturbance by human activities climate change, wetland degradation fragmentation have become common phenomenon across globe. The Guangdong–Hong Kong–Macao Greater Bay Area (GBA) is typical case. GBA has experienced explosive growth in population economy since early 1980s, which resulted complicated transitions between non-wetlands. However, our knowledge about transformation paths, associated drivers, ecological influence GBA’s still very limited. Taking advantage land use maps generated from Landsat observations over period 1980–2020, here, we quantified spatiotemporal paths analyzed drivers influence. We found that dominant path non-wetland was built-up land, accounted 98.4% total loss. primary among different types coastal shallow water paddy reservoir/pond, with strongest intensity 1980s. driving forces behind change were vary region. Anthropogenic factors (i.e., urbanization) dominated developed cities, while aquaculture had greater underdeveloped cities. findings presented this study will reference management planning GBA.

Spatiotemporal effects of landscape structure on the trade-offs and synergies among ecosystem service functions in Yangtze River Economic Belt, China

Research Square (Research Square), Год журнала: 2025, Номер unknown

Опубликована: Апрель 4, 2025

Effective landscape management is vital for maximizing the availability of ecosystem service functions (ESF). However, how pattern simultaneously affects multiple ESF across time and space, specifically regarding changes in their relationships, has not been comprehensively evaluated. Accordingly, current study examines dynamic impact on interactions among ES trade-offs China's Yangtze River Economic Belt (YREB) from 1990 to 2020. Five key are evaluated: carbon sequestration (CS), food supply (FS), habitat quality (HQ), water retention (WR), soil conservation (SC). The geographical temporal weighted regression model adopted analyze these relationships influenced by over 30 years. Over past three decades, overall amounts FS, WR, SC have increased, with only WR exhibiting a sustained increasing trend, while CS HQ significantly decreased. trade-off coordination effects generally transitioned synergies, CS–FS change more pronounced, shifting weak (− 0.29) synergies (0.20). Significant spatial variations were also observed. Most ESF. Specifically, composition stronger influence ecosystems than configuration; however, diverse often inconsistent, requiring decision-makers continuously balance management. impacts between other (CS–SC, HQ–SC, WR–SC) consistent, most prominent CS–SC. This suggests that exerts comparatively steady CS, benefiting contributions regional land parcels. These results underscore intricate responses inter-ecosystem need Cumulatively, this provides crucial guidance policymakers designing effective policies mitigate ecological degradation.

As a crucial indicator of terrestrial ecosystems, vegetation plays significant role in reflecting the interactions and coupled coordination between anthropogenic activities natural ecosystems. Understanding drivers change is paramount for achieving sustainable development socio-ecological systems. Climate are primary influencing factors change. Given current research gap understanding impacts climate on at different temporal scales within rapid urbanization process urban agglomerations, based Normalized Difference Vegetation Index (NDVI), nighttime light intensity climatic factors, this paper explores spatial-temporal distribution trend through analysis, uses empirical mode decomposition partial correlation analysis to analyzes time scales. The relative contributions were analyzed by residual method. results reveal that: NDVI exhibits an increasing most regions, Land Surface Temperature (LST) has significantly increased, intensified half regions. shows spatiotemporal heterogeneity, with correlated areas extension A strong negative activity mainly distributed core various cities. regions where negatively LST primarily located Zhaoqing, Jiangmen, Huizhou. Increases precipitation sunshine duration promote growth. influenced short term. In long-term trend, dominated changes caused These findings contribute comprehensive driving mechanisms dynamic context provide scientific basis formulating more effective ecological management strategies.
