Опубликована: Дек. 7, 2023

Constructing and optimising ecological networks in high-density cities plays an important role mitigating urban problems. Our study uses comprehensive evaluation methods such as Morphological Spatial Pattern Analysis (MSPA), the Remote Sensing Ecological Index (RSEI), Connectivity to identify source areas Fuzhou City, constructs optimises network using Minimum Cumulative Resistance (MCR) model, current theory, other methods. Meanwhile, changes landscape connectivity under different development scenarios were explored. The results show that following: (1) identification of sites based on integrated approach is better than single MSPA method; (2) City consists 44 92 corridors; (3) among various modes, transforming top 30% bare land patches into green spaces improves overall most. can provide auxiliary decision-making for construction cities.

Identifying priority conservation areas in regional ecological networks using attack scenario simulation

Global Ecology and Conservation, Год журнала: 2023, Номер 46, С. e02602 - e02602

Human activities and natural disasters are progressively damaging regional ecosystems causing ecological fragmentation. Therefore, it is essential to establish or restore effective connections between spaces that create networks exhibit structural functional resilience. This study developed a network model based on landscape ecology complexity science with indicators integrated assess the resilience of regional-scale networks. Regional priority conservation areas can be identified by disturbance simulations using capacity-load cascade failure supported model. Our research indicates in Agro-Pastoral Ecotone North Yinshan Mountain China relatively fragile. The restored stable state when rate nodes less than 20%, but will completely paralyzed percentage higher 75%. Based type comprehensive importance nodes, as well results network's resilience, we have determined different levels areas. We also made recommendations for reconfiguration spatial differentiated management. findings practical significance development adaptive planning management policies large scale restoration.

Constructing an Ecological Network Based on Heat Environment Risk Assessment: An Optimisation Strategy for Thermal Comfort Coupling Society and Ecology

Sustainability, Год журнала: 2024, Номер 16(10), С. 4109 - 4109

Опубликована: Май 14, 2024

Urbanisation is a significant driver of global climate change. It increases temperatures, impacting the health residents. To date, research on urban heat environments has focused society or ecology, overlooking value integrating two factors. The objective to integrate socio-ecological benefits, explore construction methods ecological-cooling networks, and provide reasonable guidance for planning, thus contributing alleviation risks improving thermal comfort. Using Fuzhou as an example, environmental risk framework was used construct environment assessment strategy based hazards (thermal comfort), exposure (human-development footprint), vulnerability (natural geographic conditions). source area identified evaluation results, ecological network constructed using circuit theory, key nodes were identified. Results showed that in 2005 2020, 3% 12% areas had higher risks, proportion low-risk 43% 28%, respectively. In sum, 54 locations, 124 corridors, 76 pinch points, 110 obstacle 12 stepping stones during corridors 2020. Compared with 2005, decreased by 1622.46 km2 average length corridor also 4.69 km.

Dynamic Evolution of the Ecological Resilience and Response under the Context of Carbon Neutrality

Ecosystem Health and Sustainability, Год журнала: 2023, Номер 9

Опубликована: Янв. 1, 2023

Among the background of rapid urbanization and climate change, capacity urban ecosystems to recover from disturbances has been considerably disrupted. However, existing study often lacks dynamic assessments in terms response process underlying ecological resilience. Here we use “resistance, adaptability, recovery” framework quantify resilience, resilience carbon storage emissions was investigated. The results showed that (a) Dalian demonstrated a trend continuous decline 2005 2019; (b) clustering characteristics cold/hot spots for were obvious. cold agglomerated into larger area during study. new patches mainly located southern Jinzhou downtown Dalian; (c) had clear positive impact on this an increasing trend. In contrast, negative piecewise linear regression reveal emission threshold effect, above became key management; (d) according development conclusion divided areas low reduction, high storage, stability protection zone. present provides spatial guidance investigating evolution

Integrating the functions and structures to assess ecological network sustainability under climate change scenarios

Landscape Ecology, Год журнала: 2024, Номер 39(2)

Abstract Context Developing ecological networks (ENs) is a widely acknowledged conservation strategy for mitigating habitat fragmentation and ecosystem degradation. Therefore, it crucial to assess the sustainability of ENs before or after their development in order maintain functions service. While most previous studies have explored based on service evaluation structure construction, structures EN rarely been integrally assessed under climate change scenarios. Objective Taking Yangtze River Delta urban agglomeration as study area, we aim future current multiple scenarios by integrating its structures. Methods Ten were constructed, including scenario nine Ecological sources derived from importance service, used develop using Linkage mapper toolbox. We then range difference between indicate functional EN. The NetworkX was structural stability sustainability. Results capacity 6.23% projected decline efficiently providing services 2050 selected scenarios, these degradations will also lead 33.55% decrease stability. Poor, low, medium sustainable be mostly located forests water bodies central YRDUA with small average patch while high mainly distributed southwestern mountainous regions areas north-central region larger area. Conclusion Our provides prospective assessment EN, which particularly enhancing strategies ensuring landscape Constructing assessing can provide effective information long-term management.

Amidst the rapid urbanisation, ecological environment of plateau lake basins faces significant challenges. To better coordinate relationship between urbanisation development and construction, this paper conducts an analysis assessment resilience coupling coordination in Dali Prefecture based on socio-geographical spatial data. Initially, model for is established using theory. Subsequently, level evaluated panel Finally, a employed to calculate two aspects. The results indicate: (1) increase basin from 2010 2019, particularly 2015; (2) continuous expansion low-value areas across entire basin, with predominance townships experiencing fluctuating decreases or stagnation, leading overall negative trend indices; (3) evident temporal disparities systems basin's villages towns, primarily reflected differences types, few towns consistently exhibiting environmental lag. This study introduces customised Erhai Basin, enhancing comprehension urbanisation-ecological dynamics basins.

Опубликована: Апрель 19, 2024

Urban green infrastructure (UGI), a key component of nature-based solutions (NbSs), plays vital role in enhancing urban resilience. Nonetheless, the absence thorough resilience evaluation for UGI has hindered efficacy its design and implementation. This article proposes an innovative environmental index (ERI) framework designed to evaluate lifecycle performance UGI. First, coupled system is proposed that encompasses indicators adaptation acute disturbances mitigation chronic pressures. Second, inventive formulas calculating are presented, which establish weighting through Delphi-analytic hierarchy process (AHP) analysis, Storm Water Management Model (SWMM), GaBi, i-Tree models employed quantitative assessment. Third, four representative scenarios built-up areas have been selected comparative analysis in-depth discussion by index. research presents as adaptive measures “Black Swan” events “Gray Rhino” phenomena, offering significant case studies methodological frameworks will inform future endeavours sustainable development.
