Special Issue Information

Dear Colleagues,

With the acceleration of urbanization, a large amount of natural land surface has been transformed into artificial land surfaces. The urban landscape presents a state of fragmentation, and all kinds of biological habitats gradually disappear. As an important part of the urban ecosystem, plants play an irreplaceable role in coordinating the human–nature relationship. However, studies on the response of plant community biodiversity, functional traits, and ecosystem services to urbanization are still relatively weak. Sustainability plans to organize a Special Issue to improve people’s understanding of the impact of urbanization on plant diversity from both theoretical and practical perspectives, so as to provide useful references for the development and application of plant ecology and landscape ecology and promote sustainable and high-quality development in urban regions. This Special Issue welcomes submissions including, but not limited to, the following topics:

(1) Spatial-temporal variations and its behind mechanism for Urban greenspace and biodiversity;
(2) Plant phylogenomics and biogeography, as well as taxonomic revision;
(3) Germplasm innovation and excellent genes mining for tropical crops.

Abstract

Green space is essential in urban areas to maintain, and improve human well-being. To better understand the impact of environmental and socioeconomic changes on the sustainability of tropical urban green space landscapes, work is needed to explore the patterns of plant diversity and its drivers in urban green spaces. We explore urban floristic diversity patterns based on samples from 826 urban functional units located in five cities in the tropical coastal region of China. Field surveys were conducted to obtain data on plant diversity, land use types, socioeconomic characteristics, and environmental characteristics within these units. Plant diversity within the cities varied significantly among land-use types, with high-rise housing, parks, and universities exhibiting higher diversity. The diversity of cultivated plant species and the regional economy showed a significant positive correlation (β coefficient = 0.15, p-value < 0.05), while an increase in the diversity of spontaneously growing plant species and native species was linked to building age (β coefficient = 0.12, p-value < 0.01; β coefficient = 0.13, p-value < 0.01). Management also affected plant species diversity, with watering and maintenance frequency having a positive association. Urban plant diversity patterns result from a combination of multiple factors, and different drivers affect native vs. non-native plant diversity Socio-economic factors are the primary driver of urban plant diversity patterns, as space management and maintenance determine what can grow in different areas. This study has important practical significance for policymakers and managers in developing and managing urban green spaces more sustainably. Full article
