Stand structural characteristics determine ecosystems multifunctionality of urban forests in Changchun City, Northeast China
Systems theory highlights that stand structural attributes influence overall functioning. However, the relationship between these attributes and ecosystem multifunctionality, particularly in urban forests, remains poorly understood. This study uses regression analysis and a random forest model to assess the effects of 19 indicators of stand structure characteristics on ecosystem multifunctionality of urban forests in Changchun, a representative forest city in northern China. The structural characteristics are categorized into stand structure, herbaceous layer structure, and structural heterogeneity. Multifunctionality is evaluated based on carbon sequestration, rainfall interception, air temperature reduction, humidity enhancement, PM2.5 reduction, and noise reduction. Results indicate that both stand structural heterogeneity and stand density significantly enhance multifunctionality, with structural heterogeneity having the greatest impact, followed by stand structure and herbaceous cover. Thus, optimizing stand density, increasing structural heterogeneity, and maintaining sufficient herbaceous cover are crucial for improving urban forest multifunctionality. These findings offer important implications for urban forest management and the enhancement of urban environmental quality.
期刊介绍:
Urban Forestry and Urban Greening is a refereed, international journal aimed at presenting high-quality research with urban and peri-urban woody and non-woody vegetation and its use, planning, design, establishment and management as its main topics. Urban Forestry and Urban Greening concentrates on all tree-dominated (as joint together in the urban forest) as well as other green resources in and around urban areas, such as woodlands, public and private urban parks and gardens, urban nature areas, street tree and square plantations, botanical gardens and cemeteries.
The journal welcomes basic and applied research papers, as well as review papers and short communications. Contributions should focus on one or more of the following aspects:
-Form and functions of urban forests and other vegetation, including aspects of urban ecology.
-Policy-making, planning and design related to urban forests and other vegetation.
-Selection and establishment of tree resources and other vegetation for urban environments.
-Management of urban forests and other vegetation.
Original contributions of a high academic standard are invited from a wide range of disciplines and fields, including forestry, biology, horticulture, arboriculture, landscape ecology, pathology, soil science, hydrology, landscape architecture, landscape planning, urban planning and design, economics, sociology, environmental psychology, public health, and education.
