摘　　要：2006年10月,应用线牌标记红松(Pinus koreansis)球果,采用人工放置实验和定点观察相结合的方法,对松鼠(Sciurus vulgaris)贮藏红松种子距离进行了初步研究与分析。结果表明,不同放置点的红松球果堆被松鼠发现并捕食的时间不一致,放置在人为干扰较强地点(旅游步道边)的红松球果最后被搬运走,但各放置点的红松球果均在放置10h内全部消失。新球果(2006年)和旧球果(2005年)均被松鼠捕食并贮藏,但松鼠优先选择搬运新球果。实验共放置人工标记的球果110枚,当场被取食的球果8枚,其中花鼠(Eutamias sibiricus)当场取食4枚新球果,松鼠当场取食4枚,均为旧球果;其余102枚球果被搬运并贮藏。以放置点为圆心,以300m为搜索半径,共回收标志球果47枚,回收率为46.1%。We used field observation and manipulated experiment approach to study the hoarding distance of Korean Pine （ Pinus koreansis ） seeds removed by squirrels （ Sciurus vulgaris ） in October, 2006. Total of 110 cones were marked by label and placed in 6 spots, among those cones 8 were eaten and 102 were removed hours and hoarded within 10. Total of 47 removed and hoarded corns were found within a radius of 300 m from the point placed. The results indicated that the location of cone placed had influence on the duration being found, those cones placed in the sites with a high human disturbance （near tourist path） were removed later. New cones （in 2006） and old cones （in 2005） were all predated and hoarded. Squirrels prefer to remove new cones and all the cones were hoarded, but they also removed hoarded old cones partly eaten by Eutamias sibiricus.
