摘要: 为完善生态服务价值定量评价方法，并推动绿色国民生产总值（GDP）纳入国民经济核算体系，分析了浙江天童生态公益林氮磷养分的储存和流通特征，并对其生态服务价值进行了计算。结果表明：区域尺度上，分布面积是主要决定因素，木荷Schima superba林和木荷-米槠Castanopsis carlesii林总价值最高（分别为673.46和576.05万元a－1），栲树Castanopsis fargesii林、木荷-石栎Lithocarpus glaber群落和毛竹Phyllostachys pubescens林介于中等（分别为219.52，140.65和111.84万元a－1），马尾松Pinus massoniana林、马尾松-木荷林和杉木Cunninghamia lanceolata林最低（分别为30.16和44.30万元a－1）。单位面积内，林木生产力和群落结构完整性是决定养分循环服务价值的影响因子，竹林最高（13.01万元a－1），栲树林次之（7.62万元a－1），其他类型较低。表3参14Abstract: To assess the ecological benefits as well as to help include green GDP（annual gross domestic product）into the national economic system，nitrogen （N） and phosphorus （P） storage along with their associated ecological benefits from different forests in the Tiantong Region of Zhejiang Province were studied. Results at the regional scale showed that size of forest occupying area was the major factor influencing total ecological benefit. The value was highest in Schima superba dominated forests （6.734 6 106 Yuana-1） and mixed forests of S. superba and Castanopsis carlesii （5.760 5 106 Yuana-1）；intermediate in Castanopsis fargesii dominated forests （2.195 2 106 Yuana-1），S. superba and Lithocarpus glaber mixed forests （1.406 5 106 Yuana-1），and bamboo forests （1.118 4 106 Yuana-1）；and lowest in Pinus massoniana dominated forests （3.016 0 105 Yuana-1），P. massoniana and S. superba mixed forests （3.163 0 105 Yuana-1），and Cunninghamia lanceolata forests （4.430 0 105 Yuana-1）. In per unit area，forest production and structure were main factors for ecological benefit from nutrient cycling，and the ecological benefit was highest in bamboo plantations（1.301 0 105 Yuana-1） followed by C. fargesii dominated forests（7.620 0 104 Yuana-1）.［Ch，3 tab. 14 ref.］
