摘　　要：为评价匹里青河水生生态,2017年春季对匹里青河水生生态开展调查,调查以水生生物为主。调查结果显示,匹里青河现有浮游植物31种,浮游动物2种,底栖动物12种,水生植物3种,鱼类5种。匹里青河出山口以下河道形态及水域环境由于受到人类经济活动的影响已发生了一定程度的变化,这将对该河栖息的鱼类构成直接影响。饵料生物浮游植物种类较多,硅藻为优势种;浮游动物种类较少;底栖动物12种,上游为固着卵石种类,中下游为广布种。水生植物种类较少。鱼类组成较为简单,仅5种,均为土著鱼类。In order to evaluate the aquatic ecology of Piliqing River,a survey was carried out in the spring of 2017,mainly focusing on aquatic organisms.The results of the survey shows that there are 31 kinds of phytoplankton,2 kinds of zooplankton,12 kinds of benthic animals,only 3 kinds of aquatic plants and 5 kinds of fish in Piliqing River.Due to the influence of human economic activities,the channel morphology and water environment below the mountain pass of Piliqing River have changed to a certain extent,which will have a direct impact on the fish that inhabit the river.There were more species of phytoplankton in the feed organisms,diatoms were the dominant species,fewer species of zooplankton,12 species of benthic animals,the upper reaches are fixed pebble species,the middle and lower reaches are widespread species.There are fewer species of aquatic plants.Fish composition is relatively simple,only five species,all indigenous fish.
