| 英文摘要 | With a warming climate, extreme precipitation events are projected to occur more frequently in future, which can lead to sediment and freshwater pulses to coastal waters that quickly affect water quality. Understanding how coastal systems respond to and recover from such acute events is becoming more and more important, particularly true in semi-enclosed bays with weak water exchange and purification capacities, such as Jiaozhou Bay (JZB). Based on the three cruises performed on 17 July, 5 and 22 August 2012, a coupled physical-biological model was used to examine ecosystem responses in JZB to Typhoon Damrey, an extreme precipitation event. In order to study the mechanism behind rainfall-induced changes, three groups of sensitivity experiments were set to furtherly analyze the contributions of rivers and atmospheric deposition, respectively. The results showed that typhoon-induced rainfall provided high concentration of dissolved inorganic nitrogen (DIN) and dissolved inorganic phosphorus (DIP) to phytoplankton which caused a remarkable chlorophyll-a increase subsequently. During the heavy rainfall event, the nitrogen and phosphorus inputs from river runoff were 1.80 and 2.14 times than that from atmospheric deposition, respectively. River inputs supported 2.14 times the productivity than that supported by atmospheric deposition. Rainfall-induced nutrient input will lead to blooms in coastal areas, especially in semi-enclosed bays. Since increased rainfall would trigger higher river discharge, rivers became the main carriers of nutrients. Atmospheric deposition provided a low-level supply, and it was limited for alleviating phosphorus limitation in semi-enclosed bays. Enhancing ecological monitoring of rivers and atmospheric deposition is urgent and essential to predict the response of ecosystems to extreme rainfall events. |
