Dynamics in ecosystem service values of three lower subtropical forest planta-tions in Heshan, Guangdong province
摘要
Abstract
Based on long-term forest restoration studies at the Heshan National Field Research Station of Forest Ecosystems, the dynamics of ecosystem service values of three lower subtropical forest plantations from 0 to 22 years old were revealed, using re-vised formulae and adjusted prices of the“Specification for Assessment of Forest Ecosystem Services”in China (LY/T 1721-2008). The results showed that the development of ecosystem services of subtropical forest plantations had characteristics of non-linear and desynchrony. As a whole, the value on water conservation and the total ecosystem services increased quickly at the beginning, then slowed down, and finally kept on a relative constant state with small fluctuation. The value of carbon fixation, oxygen release and nutrients accumulation in biomass, increased quickly at the beginning, and followed by a slowly decrease. The value of service func-tions on biodiversity and soil conservations kept increasing during the 22 years period, but with large fluctuations. Water conserva-tion is the most valuable services of the three subtropical forest plantation in the 22 years, followed by carbon fixation, and oxygen release and biodiversity conservation. In the first 12 years, the ecosystem service value of Acacia managium plantation was higher than that of the other two plantations, then the differences among the three plantations were obviously reduced. Finally, the mixed native species plantation caught up to be the best one on providing ecosystem services a whole.关键词
