摘要
森林生态系统是陆地上最为复杂的生态系统,它不但拥有丰富的资源,还具有巨大的环境调节功能和生态社会效益.介绍了森林生态系统中没有普通意义上的市场的一些生态服务功能价值评估和计算方法,并评价了这些方法的优劣;系统阐述了森林生态系统提供林产品、涵养水源、防洪效能、保持水土、保持养分、防止泥沙淤积、固定CO2、释放O2、吸收SO2、截留粉尘和净化大气功能的生态价值评估方法.
Forest ecosystem is one of the vegetation types on the earth surface, and is the most complicated ecosystem among various types of terrestrial ones. It is with abundant resources and with great function on the environmental adjustment and ecological social services. In the paper, we reviewed assessment index systems and estimating methods for forest ecosystem services, which were not in term of economic valuation in accordance with ordinary market, and appraised the advantage and disadvantage of these methods. We present systematically a set of evaluation methods for forest ecosystem services, including woody productions, holding water sources, flood control, protection of surface soil, maintenance of nutrient, preventing sediment, sequestration of carbon dioxide, release of oxygen, absorption of sulfur dioxide, interception of dust, and purification of atmospheric pollution.
