摘要
绿化植物保水还是耗水是一个颇有争议的问题,为了研究植物对水循环的影响,尤其是对于北京这样一个严重缺水的城市,针对在迎接2008绿色奥运之际,大力扩增绿化面积之后,水循环是否受到影响,有怎样的变化趋势,采用分析植物在水循环中的地位和作用,调查北京近几年的降水量、蒸发量及水资源总量等各项指标,并结合北京地区的实际绿化状况,进行分析处理的方法,发现北京市空气湿度有了一定增加,改善了生态环境,降低了水分蒸发量,对保护水资源有一定作用,但北京水资源总量仍呈下降趋势,绿化用水量惊人,故在绿化植物选择、合理搭配及管理方面应引起重视。
Protecting water or consuming water is an unsure issue on vireseence plant. To study the influence of plants in the cycle of water, especially for Beijing ,which is lack of water seriously and expand the green plant to beautify the city and get ready for the Olympic Games in 2008. By inquiring data about the water resource, precipitation and transpiration of Beijing in recent years, while analyzing them, found that there were some improvement for the humidity of the air and the water source was protected in some extent. But the overall water source is decreasing, which should be attached importance to.
