摘　　要：根据评估方法,得出大石门沟森林公园7项生态系统服务功能的总价值为2807.52万元/a,单位面积价值为5.62万元/(hm2·a)。其中固碳释氧功能价值最高,为1027.12万元/a,占总价值量比例36.58%,其次为保护生物多样性功能价值,为1000万元/a,占总价值量比例35.62%,最低为保育土壤功能价值,为48.52万元/a,仅占总价值量1.73%;各项生态功能服务价值量顺序是固碳制氧功能价值>保护生物多样性功能价值>森林涵养水源功能价值>净化大气环境功能价值>林木营养积累功能价值>森林游憩与生态文化功能价值>保育土壤功能价值。According to the evaluation method, it can be obtained the following conclusions ： the total value of the 7 ecosystem services of Dashi- mengou Forest Park is 28 075 200 yuart/a, and the unit area value is 56 200 yuarr/（hm2 · a）. The value of carbon fixation ＆ releasing oxygen function is 10 271 200 yuan/a, the highest is 36.58% of the total value. The biodiversity conservation function is 10 000 000 yuan/a, the second highest is 35.62% of total value. The lowest is the function of soil and water conservation, with the value of 485 200 yuan/a, only about 1.73% of the total value. The order of ecosystem service value is carbon fixation ＆ releasing oxygen function 〉 biodiversity conservation function 〉 water conservation function 〉 air purification function 〉 tree nutrient accumulation function 〉 forest recreation and ecological culture function 〉 the soil and water conservation function.
