提高城市绿地系统生物多样性的策略探讨

Strategies for the Improvement of Urban Greenland Biodiversity

生物多样性是城市景观多样性的基础,也是提高城市绿地系统生态功能的前提。通过建立城市绿地系统的生态网络,开发利用地带性物种,尤其是乡土植物并有节制地引进外域特色植物,扩大多样性物种的种群,增加绿地规模,促进公园和环城绿带的自然化,构建生物多样性高的复层群落结构,构筑具有地域性植被特征的城市生物多样性格局,提高绿地系统的生物多样性。

Biodiversity is not only the foundation of diverse urban landscape, but also the prerequisite for improving eco—function of urban green space system. The urban biodiversity featured with zonal vegetation will be constructed so as to improve the biodiversity of urban green space system through setting up the green ecological network, exploitiong the zonal plants, in partieuar the native plants, increasing controllably the foreign plants, expanding the population of diverse species in green land, increasing the green land scale, naturalixing the parks and the Green Belts, estabishing the multiple structure of higher biodiversity.
