Integrating pattern, process, and function in urban landscape ecological network planning: A case study of Harbin central city

Ecological Indicators, Journal Year: 2024, Volume and Issue: 159, P. 111671 - 111671

Published: Feb. 1, 2024

Scientific planning of landscape ecological networks can promote the overall improvement urban ecosystems, but current basis on single index and simple network extraction is not enough to support sustainable development. Comprehensively understanding mechanism ecosystem operation, this study firstly constructed an health (LEH) assessment model integrating pattern, process, function. Taking Harbin central city as area, conducting a LEH practical provide scientific for its planning. Secondly, principal component analysis (PCA), minimum cumulative resistance (MCR) model, hydrological were applied extract network. Finally, introducing complex theory optimize determine key nodes. The results indicated that (1) decreased from 0.481 0.446 2011 2020, with significant spatial differentiation. (2) 50 source landscapes 8 sink identified, fewer corridors, source-type nodes 28 weak-type selected. (3) Based LDF strategy theory, there 14 additional connectivity resilience greatly enhanced, eight identified. (4) plan presented pattern consisting "three rings, four pieces, cores, multiple corridors", which maintain development ecosystem. In addition, aims propose more efficient framework new ideas construction areas, are most profoundly urbanized in world.

A Study on the Characteristics and Influencing Factors of Soundscape Perception in Landscape Spaces of Urban Greenways

Forests, Journal Year: 2024, Volume and Issue: 15(4), P. 670 - 670

Published: April 8, 2024

The acoustic landscape directly affects people’s perceptual experience, which is crucial to enhancing urban greenways’ visibility experience. This study analyzed data from three typical greenways in Fuzhou City. By classifying and combining the space into two levels of “enclosure–coverage”, was categorized six types: covered, uncovered, open, semi-open, semi-enclosed, enclosure space. We explored characteristics soundscape perception factors affecting evaluation different spaces. results showed that differences sound sources between day night led spatial types. pressure level decreased with an increasing degree coverage. scores source were significantly degrees coverage, where open covered most sensitive sound, played a positive role harmony artificial sound. Pleasantness richness main influencing overall perception, contributing 50% 17%, respectively. Visitors’ age, residence type, visit frequency perception. conclusions provide reference for improving quality.

Optimization of composite ecological network patterns in Anhui Province based on multi-functional coupling of ecology-climate-economy

Ecological Indicators, Journal Year: 2024, Volume and Issue: 166, P. 112524 - 112524

Published: Aug. 23, 2024

Amidst global climate warming and rapid urbanization, ecological environmental issues are becoming increasingly prominent. Constructing a multi-functional coupled network pattern is essential for promoting the synergy among protection, regulation, economic development. This study focuses on Anhui Province, characterized by diverse topographical features. Utilizing "source sink" theory, employs combination of Morphological Spatial Pattern Analysis (MSPA), landscape connectivity indices, local spatial autocorrelation, circuit theory to construct single-factor networks biodiversity conservation, thermal environment mitigation, The analysis elements such as "source" areas, corridors, strategic points, nodes led formation an optimized multi-level, composite based ecology, climate, economy. results indicate that: (1) Province has 14 landscapes 31 "sink" landscapes.

Assessment of Pluvial Flood Mitigation Ecosystem Service in a Riverside City Using the Integrated Valuation of Ecosystem Services and Tradeoffs Model for Ecological Corridor Mapping

Water, Journal Year: 2025, Volume and Issue: 17(2), P. 143 - 143

Published: Jan. 8, 2025

Riverside cities are vulnerable to pluvial flooding due multiple factors, such as landscape fragmentation caused by land-use changes, which weakens the ecosystem service of flood mitigation. This is essential because it reduces impact this climatic event through water infiltration into soil. The metropolitan area Arequipa, Peru, a riverside city, currently fragmented accelerated population growth, has filled river buffer zones and agricultural areas with concrete, resulting in fragile control service. research assesses mitigation Arequipa using InVEST software 3.12.1 map an ecological corridor. results show low runoff urban environments but significant retention non-agricultural vegetation areas. Zero-runoff patches were identified sources, resistance surface least-cost path model created, yielding 57 km corridor connecting 18 sources across 12 Arequipa’s 19 districts. study highlights importance integrating services planning support green infrastructure initiatives, contribute sustainable resilient mitigating enhancing natural defenses.
