Thermal stratification is a common phenomenon in lakes and reservoirs and has a significant influence on water quality dynamics. Heihe Reservoir is a canyon-shaped reservoir in Shaanxi Province with strong thermal stratification. Therefore, eight water-lifting aerators （WLAs） were installed in this reservoir, which could overcome thermal stratification and increase oxygenation with gas flows between 20 and 50 m3/hr, and oxygenate the hypolimnion with gas flows less than 20 m3/hr. To examine the destratification efficiency of the WLA system, we used a three- dimensional hydrodynamic module based on MIKE 3 to simulate the thermal structure of Heihe Reservoir and compared the simulations with measured data. Results showed that operation of the WLA system promoted water mixing and effectively oxygenated the hypolimnion. Through the established energy utilization assessment method, the energy utilization efficiency of the WLA system was between 5.36% and 7.30%, indicating the capability of the technique for destratification in such a large reservoir. When the surface water temperature dropped to the theoretical mixed water temperature calculated by the energy utilization assessment method, reducing gas flow could save energy. This would prevent anaerobic conditions from occurring in the bottom water and maintain good water quality in Heihe Reservoir.

针对我国目前广泛开展的农村生活污水治理中收集处理模式较难抉择的问题:从技术、经济及生态环境的角度出发,确定方案评价指标体系。分别采用层次分析法(Analytical Hierarchy Process,AHP)、AHP-熵权法确定指标综合权重;结合逼近于理想解排序法(Technique for Order Preference by Similarity to An Ideal Solution,TOPSIS)进行方案排序。然后以典型的合肥市某地区农村污水治理为例,结合不同方案中污水收集处理模式的特点,对该方案优选模型的有效性进行验证。结果表明,采用两种方法确定指标权重时四种方案与最优方案的接近程度分别依次为0.770、0.319、0.259、0.026和0.970、0.236、0.060、0.003,两种方法方案优选结果基本一致,均表现为方案一明显优于方案四。

基于MIKE3软件建立黑河金盆水库三维水温模型,该模型准确的模拟出了2012年水体垂向水温变化及水体热分层结构演变,平均相对误差为1.42%.针对气温、太阳短波辐射及入库流量对水体热分层结构的影响进行了系统的模拟研究.结果显示:气温、太阳短波辐射与水体热分层的稳定性呈现正相关关系,而入库流量则与其呈现显著负相关关系.引入APE水库潜在势能指数来评估金盆水库水体热分层稳定性,并应用该模型,对金盆水库水体2014年9月至11月自然分层状态下APE指数进行模拟,与同时期人工强制混合条件下实测水体APE指数进行对比分析.结果表明,扬水曝气系统的人工强制混合作用能够有效降低水体APE指数,破坏热分层结构,促进水体混合.实验结果可为扬水曝气水质改善系统的科学运行提供依据,实现系统人工诱导混合,高效节能的持续改善水质,保障供水水质安全.

卵胎生作为卵生向胎生进化的中间状态,具有子代成活率高的特性。因此,卵胎生许氏平鲉成为我国重要的北方海水养殖对象之一。然而,大量养殖该物种又带来了一些繁殖过程中的实际问题。比如,网箱养殖的亲鱼出现明显的交配失败,导致其子代出生率极低;妊娠期亲鱼母胎器官发育障碍,导致仔鱼胎死腹中;早产、难产导致的亲鱼、仔鱼大量死亡等。本综述将针对上述问题,分别探讨许氏平鲉交配发生、妊娠维持及分娩启动相关的内分泌调控机制,以期为后续研究提供潜在思路,最终实现水产养殖问题的解决。
