Characteristics of Species Composition for Urban Spontaneous Herbs, with Ningbo, China as A Case Study
摘要
Abstract
Under global urbanization, the abundant urban spontaneous herbs play an important role in urban biodiversity, ecosystem services and environmental well-being. In this paper, aim to investigate into the species composition features of urban spontaneous herbs, data of spontaneous herbs and site conditions were collected by Stratified Random Survey in the urban area of Ningbo city in China. The species composition characteristics, including biodiversity, origin of species, chorological spectra, etc., were analyzed. For plots with different site conditions, significance of difference for species diversity was calculated by a combination of One-Way ANOVA analyses, Independent Samples T Test, and LSD Multiple Comparisons, etc. As a result: (1) Ningbo city has a high species richness in terms of urban spontaneous herbs, a total of 129 plant species belonging to 101 genera and 48 families were identified from 60 plots; (2) the chorological spectra of plants is wide, covering 12 chorological types and 4 subtypes. The Pantropic spectra occupied the highest proportion of all genera (30.8%); (3) native species dominate the investigated species, accounting for 89.9% of total species richness, 83.3% of total cover, and 83.3% of total plant individuals; (4) perennial and annual herbs were the main life forms, with 73.4% of total species; (5) According to the species frequency curve, only a few dominant species occur most frequently, while 81.1% species have frequency below 1%; (6) as a result of analyses on site conditions, significant difference only appeared on the Pilou evenness and Patrick richness among different land use types. This paper explored the species composition characteristics of urban spontaneous herbs and revealed the potential influences by human factors like land use type. Suggestions proposed in this paper would provide references for the protection of urban plant diversity and urban ecosystem during the planning and designing of cities.关键词
