【摘要】 分别计算了北京蒲洼自然保护区31个群丛的累积确限度,并按其值依次排列,得出这些群丛的优先保护顺序;同时,对群丛物种数与累积确限度间的相关性进行了分析。结果表明:同一群系下不同群丛的保护价值有可能存在较大差异,而群丛物种数与累积确限度显著相关。该结果为蒲洼自然保护区的功能区划分提供了依据。更多还原

【Abstract】 The accumulative fidelity of 31 associations in Puwa Nature Reserve was calculated and sequenced, and the order of preferential right for these associations to be protected was obtained. At the same time, the relativity between amount of species and accumulative fidelity was analysed. Result indicated that there may be significant differences among different associations in one formation, and the amount of species is significantly correlative with accumulative fidelity. The result provides a basis for Puwa Nature Reserve in dividing the functional sections.更多还原
