“绿色南京”林业工程建设生态效益评价

Green Nanjing Forestry Ecological Benefit Evaluation of Construction Projects

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。

Green Nanjing forestry engineering construction new forest monitoring part of the new forest eco-efli- ciency indicators. The results show that： the woodland in air purification （absorption of NO2, SO2 and total sus- pended particles）, to improve the micro-climate （decreasing temperature and increasing humidity, lower wind speed）, the protection ofbiodiversity （plants and soil biodiversity） have significant role in promoting. Further the val- ue of ecosystem services statistical analysis, calculated Green Nanjing Forestry Engineering 10 years （from 2002.9 to 2012.9）, the new forest ecological benefits total value of 35.115 billion yuan, an average of 35 billion / year. Purify the maximum value of the microorganisms in the air, to 8.129 billion yuan, followed by the value of biodiversity conservation, to 7.111 billion yuan.
