摘要
本文进一步拓展了作者等提出的生态位的广义定义;讨论了生态位与资源位的区别,样方与资源位的区别,生态位重迭与竞争系数的区别;分析了种间竞争的内在机制,提出了对竞争排除原理的新表述.
In this paper,the generalized definition of niche suggested by theauthor is furthur extended.Differences between resource states andniche,between resource states and samples,and between niche overlapand competition coefficients are discussed.The mechanism of interspecificcompetition is re-analysed to offer a new approach to understanding theprinciple of competition exclusion.
