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. (2) Compared 1995 2005, number corridors 2015 decreasing. Although improved, which River limited. (3) coordinated development protection optimization plan would promote functioning stability. This study recommendations network, are great significance protecting biodiversity, improving ecosystem functions, maintaining regional security pattern.

Cities are experiencing numerous challenges, adversely affecting human health and wellbeing. Urban green space provides ecosystem services that important to meet urban challenges. One type of is private gardens (yards) make up an essential part many areas. Gardens can support biodiversity provide cultural (CES) its owner. However, the provision garden benefits depends on size, design management. This study aims explore contribution owners' wellbeing (in terms CES), understand influence planning We use a conceptual framework illustrate complexities interlinkages: 'human-nature' nexus.

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

Urban forestry & urban greening, Год журнала: 2023, Номер 82, С. 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. A broad spectrum were valued highly their environment including attract provide food preferred wildlife; shade reduce heat; allow connection nature; have potential store carbon mitigate climate change; protection bushfires; aesthetically pleasing properties; produce people. however, concerns concentrated primarily on as well property injury branches. elicitation attitudes will residents' most important values strongest be explicitly taken into account when establishing community-inclusive approach planting.

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.

Studying human–nature relationships through a network lens: A systematic review

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. We examine their conceptualization means analysis, discuss challenges potentials each categories research. The study highlights diversity creativity with which distinct entities are defined enable use variety analytical SES Demonstrating increasing recognition describe since early 2000s providing an overview many useful conceptual methodological approaches, this article contributes systematizing provides practical guidance help disentangling SES. free Plain Language Summary can be found within Supporting Information article.

The impact of LUCC on the spatial pattern of ecological network during urbanization: A case study of Jinan City

Ecological Indicators, Год журнала: 2023, Номер 155, С. 111004 - 111004

Опубликована: Сен. 30, 2023

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. Therefore, this study focuses Jinan City, an important city situated downstream region Yellow River Basin, China. The utilized simulation approaches, including MSPA, MCR, InVEST model gravity model, investigate analyze City from 2000 2020. A set capturing changes network elements was proposed explore evolutionary characteristics pattern Finally, Geodetector impact mechanism findings indicate that: (1) During last two decades, development witnessed expansion approximately 588.83 km2, proportion also increased, but overall structure distribution are not balanced. (2) Despite areas, escalation resistance significant degradation functional capacity corridors, with decrease 8.37 % number primary corridors. reduced connectivity impeded efficient cycling processes ecosystems. (3) complex interactions cumulative effects led evolution transformation cropland into improved composition network, while encroachment disorderly internal types principal factors causing elements.

The ecological role of native‐plant landscaping in residential yards to birds during the nonbreeding period

Abstract Residential yards are a form of urban land use that cover considerable amount area in cities worldwide and provide important habitat for wildlife, especially when landscaped with native plants. Nevertheless, most native‐plant landscaping wildlife research the northern temperate regions world has been conducted during spring summer breeding period, leaving gap our understanding importance residential plants as habitats animals nonbreeding period. To fill this gap, we quantified ecological role native‐landscaped to avifauna throughout Greater Los Angeles (LA), California, winter which is time year region hosts high abundance diversity migratory resident birds. We surveyed birds features from October March 2020 2021 at 22 pairs native‐ non‐native‐landscaped plus 10 additional yards. had three objectives study.
