The hygrophyte , the hydrophyte and the mesophyte play an important role in the floristic elements . north temperate type ( 29 generas ) is account for dominant position in the floristic geographical elements of genera 在各类植物区系地理成分中，北温带分布属( 29属)具有明显优势，说明该地区湿地植物区系具有明显的温带特征。

4 the optimal water niche of m . h and m c are wetter than middle soil water content , belongs to mesophytes ; the optimal water niche of mosla scabra , on photosynthesis is more wetter than that of m . h and me , the optimal water niche between mesophytes and hygrophytes , and leaning to hygrophytes ; the photosynthetic water condition of m . d is arid environments , and its ecotype exits between mesophytes and xerophytes , and leaning to xerophytes . 5 m . h and m . s are locating between shade plants and sun plants , while m . c and m . d obviously belong to sun plants 4 、杭州石荠?与华荠?光合的最适水分条件是中等偏湿，其水分生态类型应属于中生植物；石荠?光合的最适水分条件比杭州石荠?与华荠?光合的最适水分条件要求更湿，其水分生态类型介于中生和湿生植物之间，更偏向湿生；小鱼仙草光合作用的水分生态条件是干旱条件，其水分生态类型介于中生与旱生植物之间，更偏向旱生。

At the same time , this paper also describes the fluctuation of soil nutrients and the contrast between soil of leguminosae and non - vegetation covering . the results are as follows : 1 ) despite the mesophyte leaf form of the ten pioneer species there were significant differences in leaf anatomical characters among them and some differences among different plants of an individual 结果表明研究区喀斯特先锋植物叶片在不同种类之间具有明显差异，这些差异除受遗传因子控制外，环境因子(主要为光照和水分)也有重要作用；生活型不同对先锋植物叶片特征有一定影响，但未表现出规律性。
