大中型兽类踪迹在野外考察及研究中的应用

在野外兽类考察过程中，由于多数兽类喜欢展昏活动或昼伏夜出，加上一些外界因素的影响，工作人员要对兽类进行直接的目的性观察和持续性研究有一定的难度．但由于动物的某些生物学特性，不同兽类的活动会在野外留下特定的踪迹，这为野外鉴别、观察和研究提供了重要的线索．本文总结了影响对大中型兽类进行直接性观察的因素、野外兽类踪迹的表现形式以及兽类的野外遗留物在有关研究中的应用，以期为野外考察与研究提供一定帮助．

Applications of Marks of Their Activities in Field Observations and Studies of Large-Sized and Medium-Sized Wild Mammals

Owing to the biological characteristics of mammals and influences of environments, it is hard for field investigators to achieve the destination observations and sustained studies of wild mammals directly. Different mammals would leave different marks of activities and special carry - overs, which have provided important clues and evidence for the identifications, observations and studies of wild mammals. The factors influencing the direct observations and the aspects which showed the marks of activities of wild mammals have been summarized in this article, and the research applications of field marks of activities and field carry - overs of wild mammals have been introduced, too. The aim of this work is to offer help for field observations and studies of large - sized and mediumsized wild mammals.
