摘　　要：通过对黑龙江省重点公益林年蓄水能力、净水能力及水源涵养能力进行了定点监测,对重点公益林生态效益评价相关方法的拟合分析,并对典型区域重点公益林的水源涵养效益进行了评价。结果表明:针叶混交林和阔叶混交林的年蓄水能力要明显高于白桦林,选定区域重点公益林可以发挥的蓄水效益、净水效益和源涵养总效益分别为19.39亿元,1.55亿元和20.95亿元。The surveillance on storage capacity ,purification ability and water conservation was kept on in the certain place during growing season .By the method of eco-benefit evaluation ,we calculated the value of water conservation in the prior non-commercial forest .Conclusion ：The storage capacity of needlesmixed forests and broadleafmixed forests are bigger than birch forest .The value of storage capaci-ty ,purification ability and water conservation in prior non-commercial forest are 1 .939 ,0 .155 ,2 .095 billion Yuan .
