With the rapid pace of global urbanization, conflict between needs human economic development and ecological conservation is becoming increasingly prominent. As an important habitat along migratory routes birds in East Asia, construction network for bird communities Foshan City essential to protect urban biodiversity. In this research, we employs Maximum Entropy Model (MaxEnt) Remote Sensing Ecological Index (RSEI) identify source sites based on migration characteristics requirements, calculated minimum threshold area by using granularity inverse method. Secondly, entropy weight method (EWM) analytical hierarchy process (AHP) are combined establish a comprehensive resistance surface. Finally, circuit theory hydrological analysis principles utilized construct network. The findings reveal following: landscape component structure best at grain size 1400 m, 1.96 km2 identified sources Foshan. A total 19 sources, spanning 636.09 km2, have been identified. These mainly clustered north, south-west east City. terms corridors, research shows existence 51 corridors with length 501.84 km. include 7 first-level 25 s-level potential (including 15 radiating routes). At same time, 88 nodes, including 10 critical nodes 78 general nodes. Lastly, closure index (α), connectivity (β), rate (γ), density (ρ) after optimization grew 0.84, 2.43, 0.89, 0.16, respectively. This study can provide data support optimizing future security pattern diversity

Ecological network construction and gradient zoning optimization strategy in urban-rural fringe: A case study of Licheng District, Jinan City, China

Ecological Indicators, Год журнала: 2023, Номер 150, С. 110251 - 110251

Опубликована: Апрель 17, 2023

Ecological network construction and optimization is an effective way to balance the contradiction between regional development ecological protection in process of urbanization. The urban–rural fringe both a frontier zone direction urban expansion important space for improving environment. However, there are few studies on how construct optimize networks fringe. In this paper, morphological spatial pattern analysis (MSPA) minimum cumulative resistance model (MCR) were firstly employed initially reveal characteristics problems security study area. Then, new strategy with multi-scenario coupling gradient zoning was proposed meet maximization integrated benefits future protection. results show that: (1) Urbanization caused high fragmentation patches, exerted strong hindrance processes. (2) distribution constructed extremely uneven, communication north–south severely difficult. optimized significantly improved respect, priority corridors will also help strengthen gradient. (3) connectivity accessibility Licheng District, enhanced its structure, which promote overall cycle better balanced (4) Policy makers should implementation green forest belts achieve This can provide scientific references biodiversity conservation, infrastructure planning, sustainable

Land use land cover change detection and urban sprawl prediction for Kuwait metropolitan region, using multi-layer perceptron neural networks (MLPNN)

The Egyptian Journal of Remote Sensing and Space Science, Год журнала: 2023, Номер 26(2), С. 381 - 392

Опубликована: Май 31, 2023

With the rapid expansion of cities, monitoring urban sprawl is recognized as a vital tool by many researchers who use this information in several applications like planning, microclimate modelling, policy development, etc. However, accurate land cover (LC) prediction still challenging, even with technological advancements. Machine learning (ML) and artificial intelligence (AI) have gained reputation amongst diverse science applications, including their popularity cover. Therefore, present study investigates performance ML-based classification algorithm random forest (RF) LC classes for 2016 2021 metropolitan region Kuwait City, Kuwait. The accuracy assessment derived maps achieved an overall 93.6% 95.3% kappa coefficient values 0.86 0.93 2021, respectively. results show increase built-up ∼11 %. were further used to predict 2026 using neural network (ANN) based on multi-layer perceptron networks (MLPNNs). It was predicted 83.6%. 15% 2021–2026, mostly observed western southern sides. outcomes exhibit that MLPNN techniques combined Remote sensing Geographic Information Systems (RS GIS) can be adopted derive fair precision. Such studies would prove valuable city governments planners improve future sustainable development strategies.

Understanding habitat isolation in the context of construction land expansion using an ecological network approach

Landscape Ecology, Год журнала: 2024, Номер 39(3)

Опубликована: Фев. 23, 2024

Abstract Context The impact of construction land expansion on regional landscape sustainability received significant attention, but the habitat isolation caused by such across urban-rural continuum calls for a closer examination. Objective This study aims to use ecological network approach assess effect imposed urban areas and rural settlements patches in Nanjing Metropolitan Area during 2000, 2010, 2020. Methods We first extracted applying morphological spatial pattern analysis (MSPA), then identified networks based comprehensive resistance surface circuit theory. Finally, we constructed two indices, index (IEI) degree (ID), evaluated differential contributions isolation. Results Our results showed total 129 within our area. These were linked 188, 186, 183 corridors years 2020, respectively. Further revealed that strongly isolated increasing human activities. Remarkably, both played pivotal roles exacerbating this isolation, with showing striking surge their impact, while continued be predominant driver Conclusions Sustainable planning should consider how uses may cause utilizes evaluate introduces applicable indicators estimating effects attributed expansion. findings hold implications informing shaping conservation policies.
