摘要
文章基于森林生态系统连续观测与清查体系,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),结合2015年上海市森林资源监测成果数据,采用分布式测算方法对上海城市森林生态系统净化大气环境功能进行评估。结果表明:2015年上海城市森林生态系统提供负离子4.14×10^(24)个;吸收SO_2 931.25万kg,吸收氟化物85.69万kg,吸收氮氧化物64.78万kg;滞纳TSP6 600.39t,PM_(10)1016.7t,PM_(2.5)252.13t。全市净化大气环境功能价值为26.2亿元,贡献最多的3种优势树种(组)为樟木林、硬阔类和灌木林,分别占25.95%,14.7%,13.34%,相对应的森林面积占全市森林资源总面积的24.94%,16.04%,11.76%。
The atmospheric purification function of urban forests in Shanghai was assessed using distribution calculation method,based on the continuous observation and inventory system for forest ecosystem and according to LY/T 1721—2008 Specifications for assessment of forest ecosystem services in China in combination with Shanghai forest resources investigation data in 2015. The result showed that the urban forest ecosystem in Shanghai supplied 4. 14×10-（24） negative-ion in 2015,absorbed 9. 3125 million kg SO2,856 900 kg fluoride and 647 800 nitrogen oxides,and removed 6600. 39 t TSP,1016. 70 t PM（10） and 252. 13 t PM（2.5）,respectively. The atmospheric purification in Shanghai was valued at 2. 62 billion CNY in total. Cinnamomum camphora stand,hardwoods and shrubs were the three dominant tree species/groups with the highest contribution to the value,which accounted for 25. 95%,14. 70% and13. 34%,respectively,and their cover area accounted for 24. 94%,16. 04% and 11. 76% of the total forest area in Shanghai,respectively.
