摘要：依据中华人民共和国林业行业标准《森林生态系统服务功能评估规范》(LY/T 1721-2008),以及陕西省森林资源数据和我国权威机构公布的社会公共数据,依托国家林业局黄龙山和秦岭森林生态国家定位观测研究站长期、连续、定位观测研究数据集,利用气溶胶在悬浮法测定叶片滞纳颗粒物物质量,采用分布式测算方法评价陕西省森林生态系统潜在的净化大气环境功能。结果表明,陕西省森林生态系统滞纳大气颗粒物TSP、PM10、PM2.5分别为1.37、27.07万t/a和8.42万t/a,提供负离子总量为1.03×1026个/a,吸收二氧化硫、氟化物和氮氧化物分别为10.68、3.72万t/a和5.95万t/a;陕西省森林生态系统净化环境总价值为4 064.98亿元/a,其中滞纳颗粒物、提供负离子、吸收污染物产生的价值分别为4 045.94、5.29、13.75亿元/a。
According to the ＂China Forest Ecosystem Service Function Evaluation Standards＂ （LY/T 1721- 2008）, based on Shaanxi Province forest resources and public data published by the authorities in China and the long-term observation data of ecological observation and research station established in Qinling Mountians and Huanglongshan Mountain, the amounts of fine particulate matter adsorbed on the leaf surface were measured. The potential atmospheric purification function of the forests in Shaanxi Province was esti- mated. The results showed that the total amounts of the atmospheric particulate matter TSP, PM10 and PM2.5, which were sustained by the forest ecosystem in Shaanxi Province were 137 million, 270 thousand and 700 t/a,84 thousand t/a respectively. The amounts of negative ions supplied by the forest ecosystem were 1.03× 1026/a. The adsorbed sulfur dioxide, nitrogen oxides and fluorides by forest ecosystem were 106 thousand and 800,37 thousand and 200 and 59 thousand and 500 t/a respectively. The economic value of purification by forest ecosystem in Shaanxi Province was 406 billion 498 million yuan/a, in which the val- ues produced by retaining fine particles, by providing negative ions, and by adsorbing pollutants were 4 045.94 million yuan/a,5.29 million yuan/a,1 billion 375 million yuan/a.
