摘 要:对雪峰山脉公益林2019年生态系统服务功能进行定量评估,结果表明:雪峰山公益林涵养水源62.68亿m 3·a^(-1),固土7033.06万t·a^(-1),固碳释氧1134.39万t·a^(-1);林木积累营养物质4.7797万t·a^(-1);提供负离子1.48×10^(25)个·a^(-1),吸收污染物28.14万t·a^(-1),滞尘475.10万t·a^(-1)。在各地级市行政区公益林中,各物质量指标均为怀化市最大,长沙市最小;在各县级行政区中,排在各物质量指标前三位的均为安化县、沅陵县和桃源县。公益林优势树种组主要是杉木和马尾松,在今后公益林的管护中,需要在杉木和马尾松林地中加大引进阔叶树种,形成混交林,从而提高其生态服务功能。The ecosystem service function of Xuefeng mountains public welfare forest in 2019 was quantitatively evaluated.The results showed that the water source was 6.268 billion m 3·a^(-1).The amount of soil consolidation and carbon fixation and oxygen release waS70.3306 million t·a^(-1)and 11.3439 million t·a^(-1),respectively.The forest had accumulated 47797 t·a^(-1)nutrients,provided 1.48×10^(25) air anion·a^(-1),absorbed 281400 t·a^(-1)pollutants,and retained 4.751 million t.a^(-1)dust.Among the public welfare forests in the administrative districts of cities at all levels,the quality indexes of each object were the largest in Huaihua City and the smallest in Changsha City.Among the county-level administrative regions,Anhua,Yuanling and Taoyuan were the top three.The dominant species groups of public welfare forests were mainly Chinese fir and Masson pine.In the management and protection of public welfare forests in the future,it is necessary to increase the introduction of broad-leaved species into Chinese fir and Masson pine forests to form mixed forests,so as to improve its ecological service function.
