为了研究森林生态系统保育土壤的功能及效益,以鹰嘴界自然保护区为研究对象区域,采用野外调查与室内分析相结合的方法,对该保护区内阔叶林、杉木毛竹混交林和杉木林3种森林类型保育土壤功能与效益进行分析,并运用影子工程法及市场价值法对保护区3种森林类型保育土壤效益进行了价值核算,旨在为保护区森林生态环境的保护和经营管理提供决策依据.研究结果表明:该保护区3种森林类型单位面积保育土壤平均经济价值大小依次为阔叶林＞杉木毛竹混交林＞杉木林;就单株林木来讲,杉木毛竹混交林由于密度过大,其保育土壤效益最低;从保肥效益讲,在杉木纯林中种植适当数量的毛竹能取得较好效果;从固土效益讲,杉木毛竹混交林中应适当减少毛竹比重.%In order to research soil conservation function and benefits of the forest ecosystem, Yingzuijie Nature Reserve was selected as a research area. Based on field investigation and indoor analysis methods, the soil conservation function and benefits of the broad leaf forest, Chinese fir forest, mixed forest of Chinese fir and Moso bamboo were investigated, and the economic values of soil conservation produced by the three types of forests were calculated by using shade engineering and market value method, which is aimed at providing basic data for the protection and management of ecological environment and waking up people to protect the environment, especially to develop the consciousness of protecting the forest resources. The results of the study show that the economic values of soil conversation for different forest types in the reserve area ranked from big to small as followings: broad leaf forest > mixed forest of Chinese fir and Moso bamboo > Chinese fir forest; for a single tree, because of it' s large density the economic value of soil conversation of mixed forest of Chinese fir and Moso bamboo was the lowest; planting some Moso bamboos with appropriate number in Chinese fir forest can enhances soil fertility; as to holding the soil, reducing some Moso bamboos with appropriate number in mixed forest of Chinese fir and Moso bamboo can achieve a better effect.
