The construction of the urban ecological network has a comprehensive effect on aesthetics, society and economy, provides driving force for sustainable development. However, we found few studies constructing optimizing networks in cities with highest human density. In this paper, landscape pattern indexes were applied to analyze characteristics morphological analysis (MSPA) identify source, connectivity region attributes revised resistance surface, was constructed by MCR model. results show that: (1) many land types mainly distributed tributaries Yangtze River, while only forest water areas occupied northwest are.

Community perceptions of ecosystem services and disservices linked to urban tree plantings

Urban forestry & urban greening, Journal Year: 2023, Volume and Issue: 82, P. 127870 - 127870

The planting of trees in streets and parks is critical for urban greening efforts that seek to improve climate-change resilience cities around the world. Ecosystem services provided by range from mitigating heat island effects enhancing human well-being conserving native biodiversity. At same time, such tree trade off with disservices include risk safety falling branches infrastructure damage root growth. Here, we performed a survey residents sub-tropical region eastern Australia determine community perceptions ecosystem linked plantings. Our aim was better understand diverse community, prior on-the-ground implementation greening, help guide programs parklands are vulnerable UHI region. We found strong evidence high level public awareness about beneficial can provide.

Biodiversity in residential gardens: a review of the evidence base

Abstract Residential gardens are a principal component of urban green infrastructure throughout the world and their potential positive contributions to biodiversity increasingly recognised. But characteristics reflect needs, values interests individual households. The present review summarises evidence from studies garden published in scientific literature, describes major themes identifies important knowledge gaps. A search Web Science database identified 408 articles on residential (1981–2022), with numbers increasing over time strong bias towards Europe (32.1%) North America (23.8%). Plants invertebrates were most frequently studied, species diversity was often correlated size habitat complexity. Botanic composition vegetation cover positively associated abundance fauna. Non-native plants contributed substantially plant some indicated benefits other linked functional attributes. Intensive management including frequent lawn mowing, fertiliser pesticide application, more formal, ‘neater’ appearance reduced biodiversity. However, results varied amongst studies, for example relation impacts mowing frequency diversity. There general paucity experimental different regimes few replicated tests recommended ‘wildlife-friendly practices’. Several importance connectivity infra-structure dispersal ecosystem functioning. Emerging threats include replacement by development, conversion hard surfaces declining plot sizes. Managing these challenges maximising value requires greater engagement policymakers planners, partnerships between public bodies private households co-ordinate local initiatives.

Abstract Understanding the complex interlinkages between humans and nature is crucial for developing strategies to effectively manage natural resources enhance resilience of social–ecological systems (SES). Network analysis bears great potential advance such comprehension SESs because it allows identifying analysing direct indirect relationships processes. As a result, number network studies in research has rapidly grown over last decade. This work systematizes existing approaches human–nature based on level integration both social ecological realms conceptualization. A structured inductive review empirical exploring wide range phenomena at interface was conducted, resulting 138 falling into three proposed categories.

Urbanization, driven by rapid economic growth, has resulted in dramatic land use/cover change (LUCC), posing substantial risks to urban ecological security. While constructing networks is a productive strategy for achieving balance between protection and urbanization, the limited research conducted on impacts of LUCC spatial patterns during urbanization poses hindrance scientific construction networks.

The application of ecological theory in urban planning is becoming more important as land managers focus on increasing biodiversity to improve human welfare cities.
