摘　　要：根据生态系统的分类,分别计算了山东省植被生态环境需水量、河流生态环境需水量、湖泊生态环境需水量、水库生态环境需水量和城市生态环境需水量,山东省生态环境需水量为上述各类型生态环境需水量之和。计算结果表明,山东省2000～2005年生态环境需水总量为342.64～345.01亿m^3。山东省2000～2005年生态环境需水保证率均小于50%,生态环境用水无法得到保证,且丰枯年份之间变化明显。The eco- environmental water demand of vegetation, rivers, lakes, reservoirs, and cities has been calculated separately according to the ecosystem classification, and the eco- environmental water demand of Shandong Province is the sum of the above various types eco-environmental water demand. The result shows the range of the eco-environmental water demand of Shandong Province from 2000 to 2005 is from 342.64 to 345.01 million cubic meter. The guarantee rate of eco-environmental water demand of Shandong Province from 2000 to 2005 is smaller than 50 %, the change between years is little and the eco-environmental water demand is unable to be guaranteed.

关 键 词：生态系统 生态环境需水量 水资源 水环境承载力 山东省
