| 摘 要：应用全收割法测定鼎湖山南亚热带常绿阔叶林林下层植物的含水率和生物量，林下植物在生长旺季的平均含水率和总生物量分别为57.52%和179.68 dw.g/m2，草本，藤本，灌木，乔木的含水率分别为65.51%，58.92%，55.70%，53.89%，有递减的趋势。根，茎，枝，叶的含水率为52.35%，54.67%，60.39%，63.26%，有递增的趋势。茎，枝，叶，根生物量占总生物量的比例约为42%，9%，22%，27%。以单株含水率计算出的林下层总生物干重a与由不同生活型的植物种各器官含水率分别算出的总生物量干重b，两者的相对误差仅为-0.94％，说明可不必分器官测定含水率而增加工作量。 |

| 摘 要(英文)：The ratio of water and biomass of undergrowths of lower subtropical evergreen broad-leaved forest in Dinghushan were measured by harvest method. The results showed that during the growing season，the average ratio of water was 57.52% and the total biomass was 179.68 DW g·m2. The ratio of water in herbs， lianas，shrubs and trees was 65.51%，58.92%，55.70%，and 53.89%， respectively. The ratio of water in roots，stems，branches and leaves was 52.35%，54.67%，60.39% and 63.26%，respectively. Among the total biomass，42%，9%，22%，27% was attributed to stems，branches，leaves and roots respectively. The relative difference between the two methods to estimate total biomass by using the water ratio of individuals and by using that of various components of each life forms was -0.94%，suggesting that the water content of undergrowths can be simply and directly determined by using the former method to avoid excess labors. |
