摘　　要：用生态经济学核算方法，定量评价了广西壮族自治区马山县弄拉次生林恢复后的生态服务价值。结果表明：恢复重建后的次生林具有极高的价值，1981～2006年弄拉次生林提供的服务价值累计超过8．82亿元人民币，其中直接利用价值为0．49亿元，占总价值的5．57％，间接使用价值为8．33亿元，占总价值的94．44％，间接使用价值远远大于直接使用价值。保护土壤价值、生物多样性的维持及科研文化价值分别为3．13亿元、1．74亿元及0．52亿元。弄拉次生林的恢复在防止水土流失、保护土壤肥力、维持或增加生物多样性和教育科研等方面具有极其重大的作用。An economic approach of ecological evaluation was used to assess the value of restored secondary forest in Nongla Na- tional Medicine Nature Reserve of Mashan County, Guangxi Zhuang Autonomous Region. Results show a high ecological value （on economical scale） of restored secondary forests in Nongla. Over the period of 25 years （ 1981～2006） accumulated total eco- system service value of Nongla restored secondary forest is estimated at RMB 0.882 billion and above. Direct use of lumber, herb and fruit is valued at RMB 0. 049 billion, 5.57% of the total forest value. Indirect use of the restored secondary forest is RMB 0. 833 billion, far exceeding the direct use value and accounting for 94.44% of the total value. Service values for soil erosion, biodiversity, research and culture are RMB 0. 313 billion, RMB 0. 174 billion and RMB 0. 052 billion respectively. Nongla restored secondary forest plays an important role in preventing water and soil erosion, sustaining soil fertility, developing biodiversity, and promoting research and education.
