The drainage of the aquitard and its implication for groundwater exploitation in Hengshui City

The deformation and the drainage of the aquitard is the main concern in the North China Plain(NCP), and the water released from aquitard compaction may be a large portion of the exploited groundwater. The skeletal specific storage of aquitard is the element parameter to the drainage of aquitard, and the undisturbed core samples are the best choice for the measurement of the physical parameters. In this study, the consolidation test was employed to analyze the skeleton specific storage of the clay sample drilled from Hengshui City, and the contribution from the drainage of aquitard to the groundwater exploitation. The results suggest the consolidation test can be utilized to understand the skeletal specific storage of aquitard, which is about 3.92×10-4 m-1 in the Hengshui. The water-saturation content of the aquitard was less than 100%, and the amount of the drainage of the aquitard was about 69% of the volume of land subsidence. The water released from aquitard compaction was about 35% of the groundwater exploitation to the deep aquifers.

Phosphorus Fractions in Water and Sediment and Their Correlations in Hengshui Lake, China

Sediment is a principal reservoir which accumulates and releases the pollutants. It is an important way of nutrients releasing from pore water of sediments to overlying water across the sediment-water interface. Five sampling sites were selected in the Hengshui Lake. Overlying water and sediments were collected in each of them. The phosphorus fractions and their relationships were analyzed. The results showed that the change of the total phosphorus （TP） in sediment was similar to that of the total dissolved phosphorus （TDP） and soluble orthophosphate （PO4^3-） in pore water. The concentrations of PO4^3- in pore water were higher than those in overlying water, reflecting a possible diffuse trend for PO4^3-P in the five zones of Hengshui Lake. It is indicated that phosphorus and other nutrients will be transferred from sediment to pore water and then to overlying water, which can lead to lake eutrophication.

Green Transport in Hengshui

I was born in Hengshui City, Hebei Province. Although it is a small city, Hengshui is getting much more bike-friendly and I think that’s really a good thing. On the one hand, people here can get some exercise by riding their bikes and on the other hand, they won’t add to the pollution in the air. However, there’s still a problem that taxi and bus drivers are too busy to pay attention to cyclists on the streets.

衡水湖垂钓的影响及应对策略

衡水湖违规垂钓现象严重,对衡水湖水域环境、生态平衡、湖边交通秩序均有一定程度影响,主要是由于垂钓者生态保护意识不强,对垂钓管理相关规定认识不足,同时巡视与执法力度不够。因此,应加强科普教育,增强公众生态环保意识;充分发挥垂钓协会的作用,促进垂钓规范化;加强休闲渔业品牌建设,减轻衡水湖垂钓管理压力;完善管理机制,常抓不懈。

衡水湖是华北平原唯一保持完整湿地生态系统的国家级自然保护区,其生态平衡对区域气候调节和生物多样性维持具有重要作用。然而,当前衡水湖湿地保护区的农业发展面临面源污染积久难消、转型升级缺乏动力、农业法规建设存在欠缺等问题。因此,衡水湖湿地保护区的农业改革应从改变传统农业生产模式、引入PPP模式加快农业转型、完善农业法规建设三方面入手,大力发展绿色低碳农业,实现衡水湖湿地保护区的可持续发展。

OBE理念下体育教育专业学生教学实践能力评价体系构建——以衡水学院为例

衡水学院体育教育专业学生的教学实践能力存在实践经验不足、理论与实践脱节、教学设计能力不足等问题。为客观全面地评价学生的教学实践能力,基于OBE理念,遵循科学性、客观性、可操作性和全面性原则,构建了体育教育专业学生教学实践能力评价体系,并对各项指标进行统计和权重分析。研究发现,一级指标中专业知识的掌握能力权重最高,说明学生在教学实践中必须具备扎实的专业知识基础;二级指标中师德修养能力权重最高,说明教师的职业道德和修养对学生的培养至关重要;三级指标中学生全面发展的关注能力权重最高,体现了学生综合能力全面发展的重要性。因此,学校应改革课程设置和教学计划,增加实践教学环节;教师应根据培养目标制定具体措施,培养学生各方面的能力,这样才能更好地培养和发展学生的教学实践能力。

河北衡水湖自然保护区水鸟多样性分布格局及其保护优先区

水鸟是反映湿地生态系统状况的指示物种,水鸟多样性保护优先区识别对自然保护区功能区划和湿地保护修复具有重要意义。于2020年5月—2021年4月,开展了衡水湖自然保护区水鸟群落的调查监测,采用GIS软件和结构方程模型等分析其不同区域水鸟群落结构和季节性变化、水鸟多样性分布格局及其驱动因素。结果表明:(1)衡水湖自然保护区不同区域均表现出以雁鸭类等游禽为优势种的水鸟群落特征,衡水湖西湖和滏东排河的水鸟物种丰富度和Shannon多样性指数最高,衡水湖东湖的水鸟种群数量最大,滏阳新河的鸻鹬类种群数量相对较大。(2)不同区域水鸟群落具有明显的季节性变化特征,春夏季涉禽数量明显增多,但仅在衡水湖自然保护区东湖、西湖和滏阳新河成为水鸟群落的优势种;9月之后各区域游禽种数和种群数量占比均明显上升,雁鸭类成为优势种群。(3)水鸟物种丰富度和种群数量较高的区域主要在自然保护区的湿地恢复区、滏东排河和小湖隔堤两侧等地;不同类群水鸟的空间分布格局差异较大,雁鸭类分布较为分散,鸻鹬类、鹤鹳类水鸟分布更为集中;栖息地状况是影响衡水湖水鸟多样性的主要因素。(4)衡水湖水鸟保护优先区包括湿地恢复区及周边区域、南李庄鱼塘、良心庄鱼塘及周边区域、东湖的姊妹东岛、小湖隔堤两侧等5个区域,占保护区总面积的8.94%。研究结果为衡水湖自然保护区的功能区划、水鸟保护策略制定、栖息地保护修复提供了相关依据。

地方高校大学生信息素养调查研究——以衡水学院为例

地方高校大学生信息素养不仅关系到大学生自身综合素质,也关系到高校为地方发展输送高素质合格人才的优劣。信息素养包括信息需求、信息知识、信息能力及信息道德四个方面。通过问卷调查方式,对衡水学院大学生信息素养基本情况进行调查,发现大部分学生非常认可信息的价值,尊重信息的知识产权,并具备一定的信息检索能力,但对信息素养的相关概念与技术了解不够,很少参加信息素养的相关培训。应该从提高信息素养认知、建立完整信息素养教育体系、提高图书馆在大学生信息素养教育中的作用三个途径,来提升地方高校大学生的信息素养水平。
