| Abstract: | This paper analyzes the forest ecosystem services and evaluates their economic value of forest ecosystem services of Dongxia forest region in Qinghai, China. The results show that average annual ecosystem service value of Dongxia forest region is about 0 81 billion yuan. Direct use value (DUV) is 3 88 million yuan, and indirect use value (IUV) is 0 80 billion yuan. IUV is far larger than DUV. In IUV, about 3 79 million yuan is of water conservation benefit, about 7 13 million yuan of soil conservation against erosion, and about 793 99 million yuan of purifying service. |
