	abstract = {Comparative analyses of species composition, community ecological quantitative characteristics, species diversity and propogation mode of Iso{\"e}tes orientalis H. Liu et Q. F. Wang communities at different succession stages were conducted by the method of space-replacing-time. The results show that at early succession stage, the community has the lowest diversity ( species richness, Shannon-Wiener index, Pielou evenness index and β diversity index) , and the abundance, coverage, important value and niche breadth of I. orientalis population are the highest, which makes I. orientalis the dominant species. At middle succession stage, the abundance, coverage, important value and niche breadth of I. orientalis population all decrease, while the community shows the highest species diversity, which makes the climax community of I, orientalis. At late succession stage, the abundance, coverage, important value and niche breadth of I. orientalis population fall to the lowest levels, and perennial herbs such as Miscanthus sinensis Anderss. and Zizania latifolia ( Griseb.) Turcz. ex Stapf become dominant species. Along with the succession process, the number of species adopting asexual/vegetative propogation increases and the main propogation strategy of the community changes from sexual propogation to asexual/vegetative propogation. It is suggested that in the process of succession, the changes of species composition, species diversity, propogation strategy of species and mesophytic habitat may be the major reason to decline of I. orientalis population.},

	abstract = {The content of main nutritional components in soil of natural habitat of two plots (Shupowan and Xiaolanhu in Songyang of Zhejiang Province) of Iso{\"e}tes orientalis H. Liu et Q. F. Wang was comparatively analyzed, and the pH value of water in plot of Shupowan was determined. On this basis, the factors of soil and water led to I. orientalis endangered were discussed. The results show that contents of organic matter, total nitrogen, available phosphorus, available potassium and total iron ions (including Fe 3+ and Fe 2+) in soil of Shupowan are 102. 7 g {\textperiodcentered} kg -1, 3.1 g {\textperiodcentered} kg -1, 18.1 μg {\textperiodcentered} g -1, 15.0 μg {\textperiodcentered} g -1 and 221. 6 μg {\textperiodcentered} g -1, respectively, and those in soil of Xiaolanhu are 122. 8 g {\textperiodcentered} kg -1, 4. 8 g {\textperiodcentered} kg -1, 13. 7 μg {\textperiodcentered} g -1, 7. 1 μg {\textperiodcentered} g -1 and 240.0μg {\textperiodcentered} g -1, respectively. The contents of organic matter, total nitrogen and available potassium in soil of Xiaolanhu are significantly or very significantly higher than those of Shupowan, while the content differences of available phosphorus and total iron ions are not significant between two plots. But the available potassium content in soil of two plots is very low, while the total iron ion content is rich. The water pH values in upper, middle and down streams of Shupowan are pH 6. 35, pH 6.53 and pH 6.49, respectively, showing approximately neutral. It is suggested that the soil type in the two natural plots is the type which the contents of organic matter, total nitrogen, available phosphorus and total iron ions are rich, and the available potassium content is low. And extreme lack of available potassium in soil and water neutralization are probably the important environmental factors to limit development of I. orientalis population.},
