Ecological Indicators, Journal Year: 2024, Volume and Issue: 166, P. 112325 - 112325

Most studies have assessed and constructed landscape ecological security patterns (LESPs) primarily from the perspective of morphology by employing morphological spatial pattern analysis, with little attention paid to fundamental ecosystem attributes (such as functions stability). Thus, this study proposed a comprehensive evaluation optimization framework for LESPs "mode function stability" integrating assessment pattern, function, stability. A was conducted using Minimum Cumulative Resistance (MCR) model in Guanzhong Plain Urban Agglomeration (GPUA) research area. The results showed that: (1) Generally, quality urban agglomerations relatively low because large area agricultural vegetation, high human interference, fragmentation, which caused levels (2) were mainly determined stability due low-quality ecosystems, rapid transformation, severe anthropogenic disturbances. (3) There variation certain type their different structures interference across space agglomerations. According "pattern-function-stability" framework, sources corridors covered natural forest crucial cornerstone constructing LESPs, rivers crop planting areas inevitably selected corridors, but needed further improvement construction. (4) can assess sustainability maintaining facilitating identification objectives or measures individual regional infrastructure construction practices.

Stability in change: building a stable ecological security pattern in Northeast China under climate and land use changes

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

Published: June 2, 2024

Abstract Climate change and land use caused by human activities have a profound impact on ecological security. Simulating the spatio-temporal changes in ecosystem service value security patterns under different carbon emission scenarios future is of great significance for formulating sustainable development policies. This study quantified four major services (habitat quality, water retention, soil erosion, storage) Northeast China (NC), identified source areas, constructed stable pattern. The results show that spatial storage, habitat NC, are relatively next 30 years, there no significant difference from current pattern distribution. SSP1–2.6 scenario priority model NC years. In this scenario, has largest resources (191,177 km 2 ) least comprehensive resistance (850.006 × 10 −4 ). At same time, relative corridor smallest, area mandatory reserve pinch points least. corridors form network distribution among sources, connecting several large sources as whole. fills knowledge gap building background global change, provides scientific basis decision-making regional resource management.

Construction of Ecological Security Patterns Incorporating Multiple Types of Ecological Service Functions for Developed Coastal Regions: A Case Study in Jinjiang Watershed, China

Land, Journal Year: 2024, Volume and Issue: 13(8), P. 1227 - 1227

Published: Aug. 7, 2024

An ecological security pattern is an essential natural solution for promoting the coordinated and sustainable development of urban growth environment within a given region. This study aims to develop comprehensive (ESP) Jinjiang watershed by integrating multiple service functions: regulation, eco-product provisions, human settlement services. Using well-established methodology “source identification—resistance surface construction—ecological corridor extraction”, we identified 322 source areas delineated 321 corridors spanning 1941.67 km, with key connecting regulation sources ordinary primarily linking provisions sources. Our results show that northern hilly regions are significant Anxi County services scattered across river valleys. integration enhances regional sustainability provides model similar coastal globally. findings offer scientific guidance balancing preservation, contributing worldwide.

Spatial and temporal patterns and risk assessment of carbon source and sink balance of land use in watersheds of arid zones in China - a case study of Bosten Lake basin

Ecological Indicators, Journal Year: 2023, Volume and Issue: 157, P. 111308 - 111308

Published: Nov. 22, 2023

In recent years, Northwest China has experienced rapid land-use transformation and urbanization. Land-use carbon emissions associated with human activities are an important cause of climate change. However, the sources sinks change in arid zone watersheds need further study. This study focuses on Bosten Lake employs a combination top-down bottom-up methods to assess spatial temporal evolution source sink balance under land use changes identify areas high emission risks. The key discoveries as follows: (1) category shows pattern "three decreases three increases." Grassland, unused land, water area have decreased, while construction arable forest increased. Cultivated significant expansion, increase 2375.71 km2. overall distribution intensities breaks through traditional boundaries, resulting more dispersed reorganization types. (2) Carbon originating from exhibit upward trend, net 1413.38 × 104 t. Construction emerges primary source, experiences highest rate migration. Grassland serves migration area. Transformations expansions contribute significantly balance. (3) risks prominent agricultural pastoral well urban core regions, gradually decreasing surrounding single-core staggered pattern. exceeds absorption, indicating imbalance These findings carry implications for promotion low-carbon high-quality development basin optimization national territorial planning.

Published: July 23, 2024

The conflict between economic development and ecological protection continues to intensify, highlighting the necessity for constructing regional security patterns (ESPs) reconcile relationship effectively. This study used GMOP PLUS model simulate future land use changes by 2030 under following three scenarios: natural (ND), (EP), (ED). Employing MSPA circuit theory, it identified source areas constructed ESP Beijing–Tianjin–Hebei urban agglomeration (BTH) from 2000 2030. results indicate that proportion of increased 22.24% in 23.09% 2020, EP scenario showing highest compared with other two scenarios. These are densely distributed northern western mountainous regions, sparse distributions southern plains. number corridors grew 603 616 having more than From 2030, were denser, shorter, variable, while those plains less dense, longer, relatively stable. Over decades, habitat species BTH increased, landscape connectivity decreased. Compared 2020 scenarios, saw an increase improved connectivity. impact on improvement primarily arose a combination socio-ecological drivers (e.g., elevation, slope, population), influence restoration key mainly stemmed factors temperature, NDVI, precipitation). findings demonstrate distinguishing different geomorphological units improve restore environment, considering drivers, is crucial restoring overall BTH.
