北京地区抗旱野生草本地被植物引种生态效益评价

Assessment of ecological benefit for the introduction of drought-resistance and wild herbaceous ground cover species in Beijing area.

北京地区气候条件恶劣,干旱缺水,适应北京地区气候条件的地被种类很少.为满足绿化的需求,通过对北京周边地区的植物调查、引种及物候观测,初步选出适合北京园林绿化利用的草本地被植物13种.通过对引种植物部分生态效益的测定,可以对其生态作用有一个定量的认识,为今后园林应用提供科学依据.试验于2005年5月中旬在北京林业大学草坪试验站进行,试验结果显示,马蔺、矮紫苞鸢尾、异穗苔草的生态效益最高,蛇莓、东方草莓、匍匐委陵菜的生态效益最低.

Few ground cover plants are available for Beijing area due to the atrocious weather and drought. In order to meet the demand of greenbelt, 13 wild herbaceous ground cover species which adapted to the situation of Beijing area were selected based on the investigation, introduction, and phonological phase observation. Their ecological functions were conducted to evaluate the ecological benefit of introduced plants, and this provided the foundation to the utilization of them in landscape. The results showed th...
