- 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(guò)去有關(guān)特有現(xiàn)象的研究主要限于定性的分析，可比性和精確性較差.該文嘗試引入特有現(xiàn)象的定量化指標(biāo)，以推動(dòng)特有現(xiàn)象的分析研究從定性水平向定量水平邁進(jìn).所引入的4種定量化指標(biāo)分別是：特有水平、特有系數(shù)、特有度以及特有綜合指數(shù).對(duì)每種量化指標(biāo)都給出了數(shù)學(xué)表達(dá)式，說(shuō)明了其區(qū)系學(xué)意義，例證和界定了這些指標(biāo)在植物區(qū)系分析中的應(yīng)用，結(jié)果表明，它們有良好的適用性.這些指標(biāo)充分地包含了植物系統(tǒng)學(xué)和植物區(qū)系學(xué)的信息.結(jié)合定性分析，這些指標(biāo)的應(yīng)用將增強(qiáng)植物區(qū)系研究的可比性，使植物區(qū)系特有現(xiàn)象的分析達(dá)到更精確的水平
