| Abstract: | A series of assessment index system suitable for forest ecosystem services of Qingshigang state-owned forest farms was set up by authors.Based on the forest survey data collected in 2009 and the data of social commonality,We accessed the ecosystem service function total values of four major forests in Qingshigang.The results showed that the total annual value is 2 062.2 million Yuan,of which,1 338.8 million Yuan for water conservation,109.8 million Yuan for soil conservation,278.8 million Yuan for carbon fixation and oxygen released,81.8 million Yuan for nutrient accumulation,16.4 million Yuan for atmosphere environmental purification,and 236.5 million Yuan for species conservation.The findings will provide scientific grounds for the forestry sustainable development,ecological and forestry health development in Qingshigang state-owned forest farms. |
