基于魚類完整性指數(shù)的黃浦江水生態(tài)系統(tǒng)評價

【摘要】：黃浦江是連接太湖與長江口的一條多功能平原感潮河流,流經(jīng)上海市中心城區(qū),干流長113.4 km。為從生態(tài)學(xué)角度揭示其污染程度,采用魚類生物完整性指數(shù)(F-IBI)對其水生態(tài)系統(tǒng)的健康狀況作了評價。2013年11月和2014年7月,采用地籠網(wǎng)、三層刺網(wǎng)和拖網(wǎng)對黃浦江7個斷面作了相同努力量的樣本采集,共獲魚類8 816尾。經(jīng)鑒定有38種,隸屬于6目12科,其中鯉形目24種,鱸形目7種,鲇形目4種。通過區(qū)分度分析和關(guān)聯(lián)度篩選,構(gòu)建了由9個指標(biāo)組成的F-IBI評價體系。結(jié)果表明,黃浦江上游水生態(tài)系統(tǒng)總體上處于"好"狀態(tài),中游及河口處于"一般"至"差"之間,而下游則較"差"。春季各有3個江段"好"或"差",1個江段"一般";秋季有4個江段"一般",2個江段"差",僅有1個江段"好"。評價還表明,黃浦江上游的3大支流中,由于承接太湖來水的斜塘呈"差",導(dǎo)致了為上海市提供約30%原水的松浦大橋斷面呈"差"或"一般"狀態(tài)。因此,保護(hù)淀山湖乃至太湖水質(zhì),是確保黃浦江上游水源地原水安全的關(guān)鍵。
[Abstract]:Huangpu River is a multifunctional plain tidal river connecting Taihu Lake and Yangtze River Estuary. It flows through downtown Shanghai. The main stream is 113.4 km. long. In order to reveal the extent of pollution from an ecological point of view, the fish biological integrity index (F-IBI) was used to evaluate the health status of its aquatic ecosystem. In November 2013 and July 2014, the net was used. A total of 8 816 fishes were collected from 7 sections of Huangpu River by three layers Gill net and trawl. There are 38 species, belonging to 6 orders and 12 families, including 24 species of Cyprinidae, 7 species of Perciformes and 4 species of Siluridae. The F-IBI evaluation system composed of 9 indexes was constructed by discriminant analysis and correlation screening. The results show that the water ecosystem of the upper reaches of Huangpu River is in a "good" state, the middle reaches and estuaries are between "average" and "bad", but the lower reaches are "worse". In spring, there are three "good" or "poor" segments, and one section "average", and in autumn there are 4 "general", 2 "poor" and only one "good". The evaluation also shows that among the three major tributaries in the upper reaches of Huangpu River, the section of Songpu Bridge, which provides about 30% raw water for Shanghai, is "poor" or "general" because of the "difference" in the inclined ponds to undertake the coming water from Taihu Lake. Therefore, protecting the water quality of Dianshan Lake and Taihu Lake is the key to ensure the safety of the source water in the upper reaches of Huangpu River.
