| 摘 要： | 对大山雀（Ｐａｒｕｓ ｍ，ａｊｏｒ）和沼泽山雀（Ｐ．ｐａｌｕｓｔｒｉｓ）巢地选择中１７个生态因子作了比较研究。通过逐乡判别分析得知：两种山雀在９个环境因子中都以平均树高，中心上层植物盖度和树种多样性三个生态因子判别力最强，为主要环境因子；两种山城８个洞因子中都以洞口短径，洞口内径和洞底短径三个生态因子判别力最强，为主要洞因子。

| Abstract: | The nest site selection variables is divided into two parts,habitats variables and cavity variables.The differences of the two tits on habitats are the century upper plant cover,average tree height and the tree species diversity.There are more obvious differences on cavity,the cavity entrance short diameter,the cavity inside diameter and the short diameter of cavity floor.All these factors are the really ecological reasons of their coexistence. |
