摘要:
淇河是海河流域漳卫河水系卫河最大支流,是河南省特有名贵优质鱼类——淇河鲫(Carassius auratus var. Qihe )的原产地。有关淇河水生植物方面的研究鲜见报道,因此,在2014-2015年对淇河河南段12个样点水生植物区系和沉水植物群落特征开展了4次研究。结果显示:共发现常见水生植物物种49种,隶属25科,42属,其中沉水植物12种,漂浮植物3种,浮叶植物1种,挺水植物10种,湿生植物23种。区系分析发现河南段水生植被呈隐域性和热带向北温带过渡的亚热带特征,植物种属以世界分布属为主,其次是北温带分布属和泛热带分布属,分别占总数的45.24%、19.04%和16.67%;这42属水生植物共有中国种子植物所占15个地理分布区类型中的8个,缺少7个。喜旱莲子草(Alternanthera philoxeroides)和水鳖(Hydrocharis dubia)分布广泛,局部堵塞罗玉村河道;沉水植物群落以轮藻(Chara vulgaris )、金鱼藻(Ceratophyllum demersum)、穿叶眼子菜(Potamogeton perfoliatus)、菹草(P. crispus)为优势种,几乎分布在各个样点,但在污染较重(如:盘石头水库出口和石河岸村)或受工程影响较大河段(如:王洞村和大来店村)种类组成较单一,群落结构较简单。总之,淇河河南段水生植物群落结构不合理、地理成分复杂程度偏低且具明显隐域性。淇河河南段水生植物保护与恢复迫在眉睫,这对保护该河段水环境质量和淇河鲫野生资源尤为重要。(图3表4参39附图1附表1)
Abstract:
Objectives: Qihe River is the biggest tributary of Wei River in Hai River Basin, as well as the original producing area of Carassius auratus var. Qihe , an important commercial cultivated fish, particularly in Henan province, China. It has not yet been reported about aquatic macrophytes in Qihe River. Methods: From 2014 to 2015, the aquatic floristic characteristics and community structure of submerged macrophytes were investigated four times from 12 sampling sites in the Qihe River Henan section . Results: There were 49 species, affiliated to 25 genera in 42 families, found in the Qihe River Henan section . Submersed, floating, floating-leaved, emergent macrophytes and hygrophytes had 12, 3, 1, 10 and 23 species, respectively. Flora analysis indicated that there were intrazonal feature of vegetation in this distinct and the subtropical transition feature from the tropical to N temperate zone, dominated by prevailing cosmopolitan, N temperate and pantropic genera (45.24%, 19.04% and 16.67%, respectively), and the 42 genera of aquatic plants had 8 areal-types, while lack of 7 areal-types in the whole 15 areal-types of the Chinese seed plants. In addition, Alternanthera philoxeroides and Hydrocharis dubia, had grown so fast and profusely that full filled the river channel in Luoyu village. In contrast, submersed macrophyte communities, particularly formed by one or three predominant species ( Chara vulgaris , Ceratophyllum demersum, Potamogeton perfoliatus or P. crispus) colonized in each site but displayed a significant decline in the diversity and community structure, especially at sections with heavily pollution or severally influenced by hydroelectric projects, such as sites that 300 m away from the exit of Panshitou reservoir, Shihean, Wangdong and Dalaidian villages. Conclusion: The Qihe River Henan section have been heavily polluted and even with water bloom, indicated by thick green color, visible to the naked eye. Meanwhile, the community structure of aquatic plants was unreasonable, and their endemic genera and geographical elements were scarce which reflects the intrazonal nature of aquatic plants in the study. So, it is urgent to manage the polluted areas and water levels charged by hydroelectric project and agricultural irrigation water, as well as to protect and restore the aquatic plants, especially the submersed macrophytes, which will be rather important steps in protecting water quality of the Qihe River Henan section and the conservation of wild resources of C. auratus var. Qihe.
