摘要

农林生态系统的生态服务功能之一是对大气环境的调节作用。归纳了农林生态系统吸收和释放气体的途径、测定方法及相关因素,以及农业管理方式和大气环境变化对农林生态系统的影响方式。从固C释O、吸收或排放CH₄和N₂O、净化SO₂等3部分提出了农林生态系统调节大气生态功能的核算公式,并列举了有关参数。根据核算,佛山市农林生态系统调节大气生态功能总价值18.18亿元。

Abstract：

The advance of the gas regulation function for an agro-forestry ecosystem, as one kind of the ecosystem services, including its pattern of receiving and releasing gas, the measure methods and relative factors, the effect for the agricultural managements and the changed atmosphere on agro-forestry ecosystem, is summarized.While being assessed, the function can be divided into three main parts(regulating C and O, absorbing or releasing CH₄ and N₂O, cleaning SO₂), then the operational assessment formulas and parameters are proposed here. The gas regulation function for the agro-forestry ecosystem of Foshan in 2005 was assessed, the result was that valued 1.818 billion yuan(RMB).

Key words： Agro-forestry ecosystem Gas regulation Ecosystem service Assessment
