摘要：为定量评估长江流域抑螺防病林生态系统的服务功能价值,科学评价林业血防工程生态效益,依据林业行业技术规程LY/T 1721-2008《森林生态系统服务功能评估规范》,选取涵养水源、保持土壤、固碳、释氧、生物多样性保护、抑螺防病6项功能对长江流域抑螺防病林的生态服务功能进行评估。结果显示:2006-2013年长江流域抑螺防病林生态系统服务功能生态效益显著,涵养水源16.16×10~8t,保持土壤1.46×10~8 t,固碳0.10×10~8 t,释氧0.29×10~8t,钉螺Oncomelania hupensis面积减少24.35×10~7 m^2,血吸虫病患者减少61.31×10~4人,总价值967.20×10`8元。其中抑螺防病功能价值最大,占全部生态系统服务功能价值的35.87%,是非抑螺防病林不具备的功能,其次释氧价值占33.06%,固碳价值占13.02%,涵养水源价值占9.17%,保持土壤价值占7.31%,生物多样性保护所占比例最少,仅有1.57%。抑螺防病林生态服务功能价值大小为湖南>湖北>江西>安徽>江苏>四川>云南,其中抑螺防病功能价值最大的为安徽省,达7省抑螺防病功能总价值的18.17%,但其余5项服务价值最大的为湖南省。研究发现,在抑螺防病林的全方位生态系统服务功能中,抑螺防病功能、释氧、固碳、涵养水源、保持土壤等5项生态服务功能价值共占生态系统服务功能价值量的98.43%,是生态服务功能的主体,各种服务功能价值量大小排序为抑螺防病功能价值>释氧功能价值>固碳功能价值>涵养水源功能价值>保持土壤功能价值>生物多样性保护功能价值。其中,湖南省对血吸虫病防治工作的高度重视使抑螺效果发挥作用最大;云南省山丘区,钉螺适生环境多样,而且其生命力强,繁殖快,血吸虫病的预防和控制难度相对较大,抑螺效益不显著。
To assess the ecosystem services value of forests for snail control and schistosomiasis prevention in the Yangtze River Basin,The Benefit Of Forestry Schistosomiasis Prevention Ecological Project,referenced as Specifications for Assessment of Forest Ecosystem Services in China (LY/T 1721-2008),was evaluated scientifically by market value method and shadow engineering method selecting water conservation,soil conservation,carbon sequestration,oxygen released,biodiversity conservation,snail control and schistosomiasis prevention to value ecosystem services.Results showed that ecosystem service ecological benefit of forests for snail control and schistosomiasis prevention in the Yangtze River Basin was great from 2006-2013 with water conservation totaling 16.16×10^8 tons,soil conservation 1.46×10^8 tons,carbon sequestration 0.10×10^8 tons,oxygen released 0.29×10^8 tons,snail area decreasing 24.35×10^7 square meters,and the number of schistosomiasis patients decreasing by 613.1 thousand.This was a saving of about 967.20×10^8 Yuan in all.Snail control and schistosomiasis prevention had the greatest value accounting for 35.87%,oxygen release accounted for 33.06%,carbon sequestration accounted for 13.02%,water conservation accounted for 9.17%,soil conservation accounted for 7.31%,and biodiversity conservation had the least value,accounting for 1.57%.The ecosystem services value for different provinces was Hunan > Hubei > Jiangxi > Anhui > Jiangsu > Sichuan > Yunnan.Of the seven provinces,snail control and schistosomiasis prevention of Anhui Province was greatest accounting for 18.17%.The other five function values were largest in Hunan Province.The study found that the comprehensive ecosystem service of snail prevention and control,oxygen release,carbon sequestration,water conservation,and soil conservation accounted for 98.43% of the ecosystem service value.The government of Hunan Province attached great importance to the prevention and treatment of schistosomiasis and undertook suppressing snail work the most.In hilly regions of Yunnan Province,Oncomelania Snail has a variety of environment,and its vitality is strong and its reproduction is fast,the difficulty of the prevention and control of schistosomiasis is relatively large,and the benefit of the snail suppression is not significant.This study provided a scientific basis for understanding the ecological role of snail prevention and control.[Ch,1 fig.5 tab.29 ref.]
