摘　　要：把千烟洲站内一个面积为14.2hm2的小流域作为案例,对第一性生产的生物量与光能利用率进行了分析。结果表明,各种植物的实际产量和理论产量还有较大差距,该小流域的发展潜力很大。The paper, based on 14.2hm2 of small watershed in Qianyanzhou Experiment Station,analyzes the biomass and utilization ratio of solar energy of the primary production. The result shows that a big gap exists between the practical production and theoretical production for various plants, indicating that there is a great potentiality of development in the small watershed.
