摘要
在黑龙江流域附属水体中共采集到80种植物,隶属于26科。芦、荇菜、(艹杂)等为优势种;线叶水马齿、小慈姑、芡实等为偶见种。利用多度、频度指数、优势度及生态类型等项指标对哈尔滨近郊10个泡沼中的水生维管束植物进行了分析。松花江及附属水体中主要为菰群落;乌裕尔河内流区主要为芦群落;在通肯河与阿伦河主要为蒙古香蒲群落与菖蒲群落。全省由南向北,植物群落由泥沼群落过渡到急流群落,群落结构也由复杂渐变为简单。对哈尔滨市水产所三个草塘进行了定量分析,按林德曼定律与陈洪达公式,推算了鱼产力。最后阐述了植物的营养价值及与其它一些生物的关系。
From the waters of the Heilongjiang River basin, 80 species of aquatic vascular plant belonging to 26 families were collected. Among them, Phramitis communis, Nymphoides peltala and Myriophyllum spicatum are dominant species, whicle Calitriche hermaphroditica, Eurgale ferox and Sagittaria natans are casual ones. The abundance, frequency- index, dominance and ecological types of the aquatic plants in 10 ponds near Harbin were anylyzed.
The major communities of aquatic plants in the Shonghua River basin are Zizania caduciflora and Uticularia vulgaris; in Wuyuer River are Phragmitis communis and Myriophyllum spicatum; in Tongken and Alun Rivers are Typha davidiana and Ranunculus kauffmannii. From south to north in the province, the aquatic plant communities gradually change from complex to simple and the type of community are becoming torrential instead of boggy.
Three ponds growing vascular plants at Harbin Fishery Institute were quantitatively analyzed. According to Lindeman's law and Chen Hongda's formula, the biomass was converted to energy content and, in turn, the potential fishery productivity.
