摘要
根据生态平衡理论,依据北京市怀柔区的实际情况,划分了北京市怀柔区生态用水类型,并将怀柔区划分为相互独立的二级生态区;计算出怀柔区各项生态用水量。结果为:全区现状生态用水总量为7.19亿m3/a。其中,森林植被生态用水量为4.65亿m3/a,水土保持生态用水量为0.83亿m3/a,城镇绿化生态用水量为0.02亿m3/a,草地生态用水量为1.29亿m3/a,河流生态系统生态用水为0.4亿m3/a。
Based on the basic ecologica1 theories,the authors classified local ecological water use types,and divided Huairou District of Beijing into two ecological zones;then calculated each type of ecological water use in Huairou District of Beijing.The results show:the whole ecological water resources is 7.19×108 m^3/a,the plant volumetric is 4.65×108 m^3/a,the ecological water use on soil and water conservation is 0.83×108 m^3/a,the ecological water use on afforested town is 0.02×108 m^3/a,the ecological water use on lawn is 1.29×108 m^3/a,the ecological water use on river is 0.4×108 m^3/a.
