| 摘 要： | 基于模糊超体积生态位,探索了多维生态位度量与一维生态位度量的联系,简化了模糊超体积生态位的度量公式,并与常用的生态位度量公式作了比较.结果表明当物种利用的各个资源类型独立时,多维生态位重叠往往大于各维生态位重叠的乘积;模糊超体积生态位的度量公式分别与Simpson指数和Schoener公式的形式相近;有助于完善生态位理论的应用.

| Abstract: | Based on fuzzy hypervolume niche,the relations of measurement between multi-and one-(dimensional) niche are studied and the formulas for making comparison with some other metric formulas are simplified.The results indicate that multi-dimensional niche overlap is usually bigger than the product of separate niche overlaps if resource dimensions are independent and the formulas are close to Simpson Index and Schoener Formula respectively.All these improve the application of the niche theory. |
