作者简介:
摘要:
乡土植物应用是应对居住区绿化植物配置与生态学 原则相悖等问题的有效措施。由于乡土植物定义繁多,缺少统 一标准,不利于乡土植物的应用。基于此,在细化广义和狭义 乡土植物定义的基础上,以重庆市106个不同建成时间的居住 区为例,探究了不同乡土植物定义下居住区乡土植物应用概 况,及其在时间尺度上的变化。结果表明,无论何种乡土植物 定义下,居住区乡土植物应用均亟待提升;在时间尺度上,乡 土植物应用并未没有得到足够改善;广义乡土植物中的长期引 种植物可以用来丰富绿化物种库。研究结果可为促进居住区中 乡土植物应用,建设生态友好型居住区绿地提供助力。

Application of Native Plants in Residences under Different Concepts of Native Plants: A Case Study of Chongqing Main Urban Area
HU Xun,YANG Yongchuan,JIN Cheng,DAI Jialing,HU Siwei
Abstract:
The application of native plants is an effective measure to cope with some problems of residential greening, such as species configuration contradicts ecological principles. However, the application of native plants is constrained by the lack of uniform standards for native plant concepts. This study refined the concepts of native plants in the broad and narrow senses. And then, taking 106 residential communities in Chongqing with different build-up times as an example, the paper explored the application of native plants in residential communities under different native plant concepts, and their changes on the time scale. The results showed that the application of native plants in residential communities needed improvement, regardless of the concepts of native plants, and the application of native plants had not been improved sufficiently on the time scale either. Meanwhile, acceptance of longterm introduced species was conducive to expanding the species pool for urban greening. These results of this study could help to promote the application of native plants in residential communities and build eco-friendly residential greening.
Key words:  landscape architecture  residential greening  native plant concept  application of native plant
