In China, the Huang-Huai Plain and middle reaches of Yangtze River, which are populated with numerous small medium-sized cities, have emerged as critical regions for future urbanization. As a result, these face significant ecological risks due to this rapid This study employs concept security pattern (ESP), synergizes landscape patterns processes by emphasizing connectivity. integration facilitates balance between ecosystem protection economic development. Utilizing Suizhou case study, framework establishing an ESP in rapidly urbanizing cities is proposed, aim addressing challenges posed A principal component involves optimizing identification sources. The ordered weighted average (OWA) method was used accurately pinpoint areas services while considering necessary trade-offs. Furthermore, sensitivity connectivity were integrated identify Subsequently, corridors, totaling area 416.08 km2 length 211.43 km, delineated using circuit theory. Suizhou, extensive urban development, particularly central area, has notably disrupted continuity northern southern regions. multifactorial superposition analysis conducted locate potential sources prevalent issues, leading formulation targeted strategies resolution. If certain modeled optimized sources, it projected that number will increase 46, covering 3090.4 km2; corridors also 799.8 km. expansion significantly enhance both network density corridor Therefore, development green infrastructure recommended improve resilience urbanized areas. Additionally, focus on enhancing bottleneck within facilitate species emphasized. approach findings broad implications other cities.

Construction and optimization of regional ecological security patterns based on MSPA-MCR-GA Model: A case study of Dongting Lake Basin in China

Ecological Indicators, Journal Year: 2024, Volume and Issue: 165, P. 112169 - 112169

Published: May 25, 2024

Ecological security pattern (ESP) represents a sound spatial arrangement of ecosystem occurring in landscape. The research on the optimization ESP aims to improve and restore functions by rationally allocating optimizing ecological elements based key issues. Constructing can enhance connectivity regional habitat patches, which is great significance for protecting restoring biodiversity, improving stability resilience, achieving sustainable development. However, it challenging task systematically resilience networks under attacks. Little has been done enhancing edge-based Based morphological analysis (MSPA), minimum cumulative resistance (MCR) greedy algorithm (GA) models, this study presents new method construct optimize ESP. Dongting Lake Basin China, typical region with rich complex landscape patterns, intensive human activities, taken as an example. results indicate that network improved its 51.62%, robustness against random attacks 41.13%, targeted 43.41%, relative initial network. Monte Carlo test verifies reliability solution. proposed be used finding structure best specific attacks, provides valuable decision-making reference land planning biodiversity conservation.

Predicting the ecosystem service values and constructing ecological security patterns in future changing land use patterns

Ecological Indicators, Journal Year: 2023, Volume and Issue: 154, P. 110787 - 110787

Published: Aug. 25, 2023

The land use and cover change (LUCC) associated with climate human activities poses a persistent threat to ecosystems, profoundly impacting ecological security. Simulating spatiotemporal changes in ecosystem service values (ESVs) security patterns (ESPs) under different future scenarios is crucial for formulating sustainable development policies. This study introduces comprehensive framework multi-scenario analysis, which combines the system dynamics (SD) model, patch-generated land-use simulation (PLUS) minimum cumulative resistance (MCR) model simulate ESV ESP LUCC using SSP-RCP provided by CMIP6. results show that three (SSP245, SSP585, SSP126), year 2050 predicted be 10.285 billion yuan, 10.248 10.327 respectively. Additionally, area of sources estimated 78.56 km2, 65.90 141.38 while lengths corridors are 428.05 km, 332.45 527.10 numbers nodes 14, 9, 15, Notably, SSP126 scenario demonstrates significant improvement compared SSP245 SSP585 scenarios, indicating effective protection land. provides valuable insights serves as reference decision-making concerning conservation resource management at county municipal scales.

Regional ecological security pattern (ESP) can provide the basis for regional territorial spatial planning and urban protection. Taking Wuhan metropolitan area as study area, a binary logistic regression model was used to quantify evolutionary driving forces transformation risk of land. An identification framework source based on "quality-risk-demand" constructed identify by calculating land comprehensive value from three aspects quality, degradation risk, human demand. The resistance surface calculated according land-use type nighttime light data, further using circuit theory range its key areas corridors, specific ESP their priority area. results showed sources were 382.4 km2, accounting 17.3% corridors in terrestrial ecosystem (TEC) 14.38 with an average width 77.8 m, including 4.99 km2 pinch points 3.71 barriers, indicating poor actual connectivity TEC.

Published: Jan. 23, 2024

Since 1971, remote sensing techniques have been used to map and monitor phenomena parameters of the coastal zone. However, updated reviews only considered one phenomenon, parameter, data source, platform, or geographic region. No review has offered an overview that can be accurately mapped monitored with data. This systematic was performed achieve this purpose. A total 15,141 papers published from January 2021 June 2023 were identified. The 1475 most cited screened, 502 eligible included. Web Science Scopus databases searched using all possible combinations between two groups keywords: geographical names in areas platforms. demonstrated that, date, many (103) (39) (e.g., coastline land use cover changes, climate change, urban sprawl).
