| 摘 要： | 对中国科学院千烟洲试验区大气降水特征及人工林树干茎流进行了研究，结果表明：年降雨量大部分集中在3～9月份，其中以5月份最大，日降雨量低于5.0mm的小雨较多。以木荷林的干流量最大，为100.54mm，其次是蓝桉，为66.96mm，其它的顺序分别是：枫香41.21mm、喜树36.73mm、苦楝28.26mm，湿地松最小，为15.97mm。6种森林类型干流量的月际变化基本上都是随着降水量增加而增加，其中以木荷林较为明显。但是各森林类型的干流率则大致相同，有时降水量增大干流率反而减少，如2月份降水量仅8.3mm，6种森林类型的干流量分别只有0.57mm、0.39mm、0.03mm、0.16mm、0.12mm和0.41mm，干流率却分别达到6.87％、4.60％0.36％、1.93％、1.45％和4.94％；4月份的降水量达到了218.9mm，干流率却分别只有6.03％、2.61％1.05％、2.45％、1.87％和4.33％。

| Abstract: | Studies were made on the characteristics of precipitation and the stemflow of constructed forest in Qianyanzhou Station, the experiment station of CERN, CAS. The results show that the precipitation mostly occurs from May to September, with the largest monthly precipitation being in June, the most daily precipitation being less than 5.00 mm. The stemflows of Schina superba, Eucalyptus globulus, Liquidambar taiwaniana, Camptotheca acuminata, Melia azedarach and Pinus elliottii Alanceolata were 100.54 mm, 66.96 mm, (41.217 mm),36.737 mm, 28.267 mm and 15.97 mm respectively. The monthly variation of the stemflows of the six kinds of studied species was significantly positively consistent with the precipitation, especially the Schina superba. The ratio of stemflow to precipitation (S/P) was similar among the six species, and sometimes it was negatively consistent with the precipitant. For example, the precipitant was 8.3 mm in February and the stemflows of Schina superba, Pinuselliottii and Cunninghamia lanceolata were 0.57 mm, 0.39 mm ,0.03 mm ,(0.16 mm),0.12 mm and 0.41 mm respectively, however, the ratio of S/P were 6.87%, 4.60%,0.36%,(1.93%),1.45% and 4.94% respectively. On the contrary, the precipitant was 218.9 mm in April and the stepflows of Schina superba, the ratio of S/P were 6.03%, 2.61%,1.05%, 2.45%,1.87%and (4.33%) respectively. |
