高职院校社会体育专业的建设现状与发展对策

高职院校是否具备开设社会体育专业的条件,首先要分析办学思路的定位是否准确、师资配置是否合理、是否具有专业建设的支撑学科、是否搭建多元化的实习基地等.确定培养目标的多元性、调整和完善课程设置体系、加强实践环节是社会体育专业人才的培养的依据,是实现社会体育专业的可持续性发展策略.     

Exploration on ecological regulation of the reservoirs

Reservoir regulation process in the Yangtze River basin is mainly divided into two types of flood regulation and initiating benefit regulation. The present reservoir management system and operation mode are mainly for dealing with or coordinating of flood control and benefit initiation as well as benefit distribution among various beneficial functions. From the view point of river ecosystem protection, the current regulation mode has two kinds of problems ： firstly, most of the reservoir regulation plans do not consider ecosystem protection at downstream of dams and needs of environment protection in reservoir areas; secondly, integrated regulation or management of water resources is ignored. It is very necessary to improve reservoir regulation mode, bearing problems faced by regulation of the Three Gorges reservoir and issues related to cascade development and regulation in Tuojiang and Minjiang River basins in mind. In accordance with the concept of scientific development, and the philosophy of ＂ensuring a healthy Yangtze River and promoting the harmony between human and water＂, taking flood control, benefit initiation and eco-system as a whole, this paper put forward the basic consideration to improve reservoir regulation as follows ： on the basis of requirements of ecosystem protection at downstream of dams and needs of environment protection in reservoir areas, we should bring the functions of reservoir such as flood control and benefit initiation into full play, control the negative influence to the ecosystem at downstream of dams and the environment in reservoir areas in an endurable scope, and restore the ecosystem and the environment step by step. This paper put forward the relevant regulation process aiming at the idiographic problems such as protection of ecosystem at downstream of dams and environment in reservoir areas, protection of aquatic wildlife species and fish species, regulation of sediment and protection of wetland.

潮汐河口闸下淤积及减淤措施试验研究

结合盐灌船闸泥沙模型模型,研究闸下泥沙淤积规律,探讨减少闸下泥沙淤积的工程措施。试验研究表明：盐灌船闸修建后,下游引航道内的淤积是严重的;利用汛期部分水量由船闸集中放水冲沙,对清除下游引航道的泥沙淤积是有效的;在泄水冲沙同时采用机船拖耙等搅沙措施,能大幅度提高冲沙效率;改斜坡式断面为直立式断面,缩小下游引航道的过水面积,不仅能减少淤积量,而且有利于提高冲沙效率。
