In order to improve people's awareness for the value of forest ecosystem services of protecting the ecosystem, and provide the basis for forestry management. The study has evaluated regulation service value of forest ecosystem services by using approaches such as shadow engineering method and benefit transfer method, etc. in Zhalantun city of eastern monsoon climate zone, Great Khingan Range. It could provide abundant timber and forest by-products for human beings etc., and also effectively play ecosystem services, and maintain environmental conditions for the survival of humans and support the global ecological balancelike water and soil conservation, and maintain the biodiversity. The results showed that the total value of forest ecosystem services was 342.641 billion RMB in Zhalantun city, according to the researching results. The order of ecological benefits value was: carbon fixation and oxygen release (2572.15x10(8) Yuan)>soil conservation (605.39x10(8) Yuan)>water conservation (150.85x10(8)Yuan) > forest agricultural protection (98.02x10(8) Yuan). The highest value of ecosystem services were carbon fixation and oxygen release, soil conservation, accounting for 75.07%, 17.67% of the total value, respectively, and their total value of ecosystem services accounting for 92.74% for the total value. The value of solid carbon and release oxygen per unit area was 317300 Yuan per hectare annual. The elm of carbon fixation and oxygen release value in the unit area, which was biggest, was 4.1181 million Yuan per hectare annual, and the second aspen was 944800 Yuan per hectare annual. The dahurian larch was smaller, which was 223400 Yuan per hectare annual. The soil conservation value per unit area was 45900 Yuan per hectare annual, with betula davurica highest soil conservation value per unit area (64400 Yuan per hectare annual), followed by oak (60500 Yuan per hectare annual), aspen was minimum(27100 Yuan per hectare annual). The water conservation value per unit area was 12700 Yuan per hectare annual, with betula davurica highest water conservation value per unit area (24100 Yuan per hectare annual), followed by willow (19300 Yuan per hectare annual), poplar was minimum(4400 Yuan per hectare annual). The output value of maize was increased by 57.46 billion Yuan annual, which accounted for 58.6% of the annual output of various crops. The minimum amount of cereal with the least amount of output was 0.62 billion Yuan annual, 0.6 percent of the annual output of various crops. The forest ecosystem services have not been fully utilized in Zhalantun, like soil conservation, water conservation and forest agricultural protection, etc. It was suggested that the soil erosion caused by the local forest and grassland degradation was serious and the biological diversity index and grain yield decreased significantly. Therefore, the government of Zhalantun should strengthen the protection of ecological resources, construct water and soil erosion controlling and dynamic monitoring based on small watershed as a unit, transform slope farmland, build farmland shelterbelts, establish accountability system for the protection of cultivated land, improve the compensation system for land requisition, and ensure not suitable for cultivation in an orderly way and improve the quality of arable land. It should plant more forest category, which can generate large value of forest ecosystem service. The rational management and optimize the use of local forest resources has important significance.
