英文摘要	based on a time-series dataset and the mass balance method, the contributions of various sources to the nutrient discharges from the yangtze river to the east china sea are identified. the results indicate that the nutrient concentrations vary considerably among different sections of the yangtze river. non-point sources are an important source of nutrients to the yangtze river, contributing about 36% and 63% of the nitrogen and phosphorus discharged into the east china sea, respectively. nutrient inputs from non-point sources vary among the sections of the yangtze river, and the contributions of non-point sources increase from upstream to downstream. considering the rice growing patterns in the yangtze river basin, the synchrony of rice tillering and the wet seasons might be an important cause of the high nutrient discharge from the non-point sources. based on our calculations, a reduction of 0.99 tg per year in total nitrogen discharges from the yangtze river would be needed to limit the occurrences of harmful algal blooms in the east china sea to 15 times per year. the extensive construction of sewage treatment plants in urban areas may have only a limited effect on reducing the occurrences of harmful algal blooms in the future.
