| Summary: | 碩士 === 國立嘉義大學 === 應用數學系研究所 === 98 === In the ecology, it is the important topic for the compariosn of two assemblages, mainly using the similarity indices to measure their similarity of two assemblages. The similarity indices can be divided into two types, the incidence indices and the abundance indices.
The content of this paper is divided into three parts. In the first part, we discuss the range, the linear and invariable properties of incidence indices, and then derive the order of incidence indices. In the second part, we will introduce the way that the abundance indices would be transformed from the incidence indices. And then we discuss the range of the abundance indices and derive the order of these indices. Finally, we will analysis three data set, respectively the data of the bird frequency records of the estuaries of the south region of Hsinchu, the Hong Kong big bird race data, and the data of the seedlings and saplings of in an LEP
