  1. Plant endemism is the key problem in floristic study. analysis of endemism in a flora has significant implications in demonstrating floristic richness and diversity, the relationship between plants and their environment, and also in conserving biodiversity of the flora. in view of the situation that most of the past studies on endemism were qualitative, this study is the first tentative approach to the introduction of quantitative indices to the analysis of floristic endemism, with an purpose to push the study of endemism from qualitative to quantitative. four quantitative indices are introduced, i. e. level of endemism ( l ), coefficient of endemism ( c ), degree of endemism ( d ) and general index of endemism ( a ). mathematical formulae have been given to each of the above indices and explanations for them have been presented, and the scope of their use in floristic studies has been delimited and exemplified in this paper. the result shows that they are of good applicability. the proposed indices embody full information of plant systematics and plant geography. with the aid of qualitative analysis, the application of the proposed indices will improve the comparability and precision of endemism study in floristics

    過去有關特有現象的研究主要限於定性的分析，可比性和精確性較差.該文嘗試引入特有現象的定量化指標，以推動特有現象的分析研究從定性水平向定量水平邁進.所引入的4種定量化指標分別是：特有水平、特有系數、特有度以及特有綜合指數.對每種量化指標都給出了數學表達式，說明了其區系學意義，例證和界定了這些指標在植物區系分析中的應用，結果表明，它們有良好的適用性.這些指標充分地包含了植物系統學和植物區系學的信息.結合定性分析，這些指標的應用將增強植物區系研究的可比性，使植物區系特有現象的分析達到更精確的水平
