Sediment chemistry and nutrient influx in a hydrologically restored bottomland hardwood forest in Midwestern USA

Exchanges of total N and C between a river and its floodplain forest have been enhanced by sedimentation processes during flood pulses at a 5‐ha bottomland hardwood forest located at the Olentangy River Wetland Research Park in central Ohio. In the spring of 2000, the forest was hydrologically restored by notching an artificial levee that had separated the Olentangy River and its floodplain forest for 100 years. One‐hundred flat sediment traps (30 cm × 30 cm) were used to collect sediment samples during spring/summer flooding events from 2003 to 2005. Results showed that sediment deposition is determined by the landscape variability during flooding events, Net sediment deposit in the wettest area averaged 134 ± 12 g‐dry wt m^?2 in 2003, 127 ± 17 g‐dry wt m^?2 in 2004 and 149 ± 23 g‐dry wt m^?2 in 2005. Total N and C sedimentation ranged from 0.49 to 0.92 g‐N m^?2 and 5.2 to 19.9 g‐C m^?2. Fe dominates the sediment chemistry and results show the elemental abundance in the order of Al > Fe > Ca > K > Mg > S > P > Na > Mn > Zn > B > Cu > Mo. A hydrologic pulsing index (HPI) could be used as an indicator for mass changes of energies with hydrologic pulsing events. Restoration of seasonally flooded bottomland forests could stimulate potentially large nutrient and Fe releases, which would eventually lead to an enhanced forest productivity and biodiversity.

官厅水库水质趋势分析及对策研究

官厅水库水质污染曾经比较严重，于1997年退出了北京市饮用水水源体系。经过9年的综合治理．官厅水库水质有明显改善。通过采用PWQTrend水质污染趋势模型分析软件．对官厅水库库区近9年来的水质监测资料进行模拟计算，并对水质趋势进行分析研究，发现官厅水库库区有一部分项目明显好转．还有一部分项目有污染加重的趋势，进而提出官厅水库水污染控制及治理的对策和建议。     

边坡稳定影响因素及稳定分析方法探讨

在明确边坡稳定性取决于边坡自身的结构特性、水、振动、人类活动、气候条件、风化及植被等内外因素综合作用的前提下,对边坡的稳定分析方法从定性到定量的发展过程进行了分析。定性分析法主要有地质历史力学分析法、工程经验类比法和图解法等;定量分析法主要有极限平衡法、有限单元法、能量平衡法、控制理论分析法、智能技术分析法以及综合分析法等。针对现有边坡稳定分析方法存在的利弊,提出了需要深入研究的问题,以完善边坡稳定性的研究内容。
