以“绿色南京”林业工程建设新增林为研究对象,监测了新增林的部分生态效益指标。结果表明:林地在净化空气(吸收NO2、SO2和总悬浮颗粒物)、改善小气候(降温增湿、降低风速)、保护生物多样性(植物和土壤生物多样性)等方面均有明显的促进作用。进一步对其生态服务价值进行了统计分析,计算出“绿色南京”林业工程实施10年来(2002.9~2012.9),新增林产生的生态效益总价值为351.15亿元,平均35亿元/年。其中,净化空气微生物价值最大,为81.29亿元,其次为生物多样性保护价值,为71.11亿元。
Taking “Green Nanjing” new forest construction as the research object, some indicators of ecological benefits of newly added forest were monitored. The results showed that the forest land could promote the air purification (absorbing NO2, SO2 and total suspended particulates), improving the microclimate (cooling and humidifying, reducing the wind speed) and protecting the biological diversity (plant and soil biodiversity). Furthermore, the ecological service value was further analyzed and the total value of the ecological benefits of newly-added forests was 35.115 billion yuan (averaged 3.5 billion yuan / year) in the past 10 years (2002.9 ~ 2012.9) after the implementation of the “Green Nanjing” forestry project . Among them, the largest value of clean air microorganisms, was 81.29 billion yuan, followed by biodiversity conservation value of 7.111 billion yuan.
