城市植物多样性应用及其实现途径

A study on the application of plant diversity and its realization in urban areas

城市植物多样性是生物多样性保护的重要组成部分。近年来,我国城市生态环境与园林绿化建设快速发展,但普遍存在植物物种单一、群落生态功能差、景观单调、忽视乡土植物等现象,其核心问题是植物多样性应用严重不足。在国内外研究现状的基础上,提出了我国城市植物多样性面临的问题与解决途径,即加强园林植物引种驯化工作,重视城市园林苗圃建设,强化植物配置,开展相关政策机制研究。

City plant diversity is an important basis for improving urban ecological environment, for enriching city landscapes, for highlighting geographical features and for promoting the sustainable development of regional society, economy and environment, is also an important part of biodiversity conservation. During the recent years, Chinese ecological environment and landscaping construction have shown a trend of rapid development. However, there exist prevalent phenomena of single plant species, poor ecological function of communities, monotonous landscapes, negligence of native plants and so on. The core issue is serious shortage of plant diversity applications. Based on the study at home and abroad, problems and solutions on plant diversity in cities are put forward in this paper, i.e. , strengthening domestication of garden plant species, devoting much attention to the urban nursery and plant disposition, placing much weight on the study of relevant policies, and exploring the approach for ecological landscape architecture.
