中文摘要：

本研究针对现有西湖钱塘江引水模式下存在的湖内流场死角问题，通过系统的多学科调查、湖泊生态需水与水文、水动力学过程分析，以及物理和数值模型模拟，解析出西湖引水的主要问题，提出了湖泊生态引布水调控优化方案；针对钱塘江引水中高氮问题，研发引水高效降氮技术并开展示范，为西湖水质改善及湖区的生态恢复创造条件；针对西湖西部水域水生植物生活型单一、群落稳定性差以及北里湖高含水率香灰土底质等问题，通过生境诊治，构建了以沉水植物为主的复合水生植物群落，增强了水体自净能力和湖泊景观功能。通过工程示范，消除了示范湖区除荷花区外的死水区，显著缩短了污染物在湖泊的水力停留时间，在引水和生态修复共同作用下，示范湖区透明度提高20cm以上；钱塘江引水经处理后出水TN降至1.5mg/L以下，去除率达到40%以上；形成以沉水植物为主，浮叶和挺水相结合的复合植物群落，示范区盖度达32.93%；水质明显改善，氮磷浓度较同期下降10%-15%，多样性指数提高67%。研究成果支撑了西湖综合治理工程，为我国典型南方城市景观湖泊治理提供技术借鉴。

英文摘要：

In this study, we have proposed an optimization scheme for ecological regulation of lake water dilution and distribution, aiming at the problem of dead corner in flow field within West Lake caused by the existing dilution mode from Qiantang River. The optimization scheme was to solve the main problems concerning West Lake dilution, which were resolved through systematical multidisciplinary investigation, analyses of lake ecological water requirement, hydrological and hydrodynamics processes, and physical and numerical model simulations. Aiming at the problem of high nitrogen from Qiantang River water dilution, we have developed high-efficient nitrogen removal technologies and carried out demonstration projects, to create conditions for the improvement of water quality and ecological restoration of West Lake. In the western part of West Lake, the life style of aquatic plants was simple; the stability of community structure was poor and the sediment of Beili Lake was of high moisture and incense. Aiming at these problems, through habitat diagnosis and treatment, a composite aquatic plant community dominated by the submerged macrophyte was built, to enhance the self-purification capacity of water body and the landscape function of the lake. Owing to the demonstration projects, stagnant water areas were eliminated except the lotus region; hydraulic retention time of the pollutants in the lake was significantly reduced; the transparency in the demonstrated lake areas increased by 20 cm, due to the effects of hydraulic dilution and ecological restoration; total nitrogen (TN) in the effluent of Qiantang River dilution after treatment decreased below 1.5mg/L, with its removal efficiency over 40%; the composite aquatic plant community was formed, which was dominated by the submerged macrophyte and accompanied with floating and emergent plants, and the coverage in the demonstrated area was up to 32.93%; water quality was significantly improved, with decreases in nitrogen and phosphorus concentrations by 10% -15% from the year-ago period and increases in the diversity index by 67%. The research findings supported the West Lake Integrated Treatment Project and provided technical references for landscape lake management in typical southern city of China.
