| 摘 要： | 植被是城市生态系统中重要的组成部分,研究植被的生态需水、以及由生态缺水导致的服务功能变化具有重要意义。采用面积定额法,估算出北京市植被的最小生态需水量为37.4亿m3;采用情景分析方法,分析了不同植被类型、人均生活用水增加、人口增加情景下生态缺水量及其导致的生态服务功能变化。污水、中水回用、植被蓄水与雨水收集是缓解生态缺水的有效措施。

| Abstract: | Vegetation is one of the important parts of urban ecosystem.Researching about ecological water demand,shortage and its change of ecosystem service is of very significance.Using Area-Ration approach,the ecological water minimum demand of vegetation in Beijing is calculated about 37.4×108 m3.Using scenario analysis method,the change of vegetation ecosystem service under different vegetation type,increase of living water requirement per person and population increase is analyzed and estimated.Reusing of pollut... |
