北京有十分丰富的园林树木资源。由于各种原因,这些园林树木资源并没有得到充分的利用。为了提高北京的绿化水平,我们应当努力开发利用这些资源。当前气候的变暖;城市中高大建筑物的增加;绿化施工、养护中新技术的应用为新优园林植物在绿地中生长创造了有利条件。我们应当利用这些有利条件,在苗圃中努力繁育那些在北京能够生长,但在园林绿化中很少应用的树种。并加强科研成果的推广,在绿化设计中大胆使用新优园林植物,把北京的园林绿化搞得更好。 Beijing is very rich in garden tree resources. Due to various reasons, these garden tree resources have not been fully utilized. In order to raise the level of greening in Beijing, we should make every effort to exploit these resources. The current climate warming; the increase of tall buildings in the city; the application of new technologies in greening construction and conservation has created favorable conditions for the growth of new gifted garden plants in the greenbelt. We should take advantage of these favorable conditions and strive to nurture those tree species that can grow in Beijing but are rarely used in landscaping in nurseries. And to promote the promotion of scientific research, green design in the bold use of new garden plants, landscaping in Beijing and make better.
