Abstract: From September to December of 2001 , two experiments were conducted to study the effects of seed species ( Quercus varialilis , Q. serrata , Castanopsis fargesii , Lithocarpus harlandii , Cyclobalanopsis glauca , and Camellia oleifera) and burial depth (0 - 1 cm , 1 - 2 cm , 2 - 4 cm , 4 - 6 cm , 6 - 8 cm and 8 - 10 cm) on seed recovery in the arenas by female adult Edward’s long-tailed rats ( Leopoldamys edwardsi) , a dominant rodent species in the forest of Dujiangyan Region of Sichuan Province , China. The results showed that : 1) Due to the variation in seed size , nutrient value and tannin content among the six tree seed species , the seed species did significantly influence seed recovery by female adults : the highest for L. harlandii seeds (the biggest seeds) , second for Camellia oleifera (high fat content) and Castanopsis fargesii (low tannin content) , and lower for the other three seed species (high tannin content) ; 2) There was a significantly negative correlation between burial depths and seed recovery of Q. varialilis by female adults. That is , female adults recovered the lower proportion of seeds as the seeds were buried deeper from 0 - 1 cm to 8 -10 cm.

摘要： 2001 年9 ～12 月, 在四川省都江堰林区实验围栏内研究了栓皮栎、枹树、栲树、石栎、青冈和油茶种子与6 种埋藏深度对小泡巨鼠雌性成体发现埋藏种子的影响。结果表明: 1) 由于不同种子在种子大小、营养价值和单宁含量等存在差异, 雌性小泡巨鼠对个体最大的石栎种子发现率最高, 油茶(脂肪含量高) 和栲树(单宁含量低)次之, 单宁含量较高的枹树、青冈和栓皮栎则较低; 2) 埋藏深度与雌性小泡巨鼠发现栓皮栎种子的比例呈显著负相关, 即随着埋藏深度增加, 小泡巨鼠发现埋藏种子的比例则减少。
