【摘要】 长期以来,人们一直认为水生植被是隐域植被,无明显的地带性分布规律。本文据现有资料,从区系,地理分布和植被类型等方面的证据,初步论证了水生植被地理分布的水平地带性和垂直地带性,并剖析了以往导致人们认为水生植被是隐域植被的原因,进而提出了正确地认识水生植被地理分布规律的途径。更多还原

【Abstract】 For a long time, the blief had been held that aquatic vegetation was nonzonal and had no evident distributional zonality, Based on the data so far known, the present paper elucidated the very neglected fact that there existed indeed a relatively obvious zonality of both the horizontal and vertical distribution of aquatic vegetation in view of the floristics, geographical distribution and vegetation of water plants, Also, analysed were the causes resulting in taking aquatic vegetation for non-zonal vegetation, Finally, presented were the correct ways to understand the geographical distribution of aquatic vegetation,更多还原
