摘　　要：本文采用水分平衡法对东北国有林区森林生态系统服务功能之涵养水源进行估算,结果表明:东北国有林区森林生态系统每年调节水量共计410.6亿m3?a?1,分别是黑龙江109.3亿m3?a?1,吉林197.3亿m3?a?1,内蒙古104亿m3?a?1。涵养水源价值总量为5306.8亿元?a?1,分别是黑龙江1832亿元?a?1,吉林2279.8亿元?a?1和内蒙古均1195亿元?a?1。从森林类型来看,涵养水源价值量最多的是阔叶混交林,落叶松林次之,樟子松林最少。In this paper, the water balance method was used to estimate the conservation water source of forest ecosystem service function in northeast China’s state-owned forest regions. The results showed that the annual regulation water amount of forest ecosystem in northeast China's state-owned forest regions was 41.06 billion m3?a?1, which was 10.93 billion m3?a?1 in Heilongjiang province, 19.73 billion m3?a?1 in Jilin province, and 10.4 billion m3?a?1 in Inner Mongolia. The total value of water conservation is 530.68 billion yuan?a?1, 183.2 billion yuan?a?1 in Heilongjiang prov-ince, 227.98 in Jinlin and 119.5 billion yuan?a?1 in Inner Mongolia. In terms of forest types, broad-leaved mixed forest had the most water conservation value, followed by deciduous pine forest and Mongolica forest.
