分析河道疏浚工程、疏浚砂石的特点，揭示长江河道疏浚砂石的自然资源属性并未改变的本质，其处分权/出让权、收益分配权的归属与长江河道采砂权许可以及采砂收益分配的归属类似；在研究典型河道砂石交易方式及疏浚砂石利用特点的基础上，提出长江河道疏浚砂石宜采用“采砂作业+砂石出让”的交易方式，将河道疏浚施工作业与疏浚砂石资源交易的主体分开；在分析长江河道疏浚砂石利用主要环节的基础上，构建长江河道疏浚砂石利用管理...
三峡水库蓄水后，库区众多支流下游形成库湾回水区，这些库湾回水区是库区水环境调整最为活跃的地区. 为了探究支流库湾对于库区生源要素循环及物质通量的作用和意义，于2012年8月~2013年7月对草堂河库湾、相邻干流、支流上游水体中溶解态无机氮（DIN）、溶解态无机磷（DIP）、溶解态硅酸盐（DSi）的时空分布进行逐月现场观测. 结果表明，草堂河库湾回水区营养盐的浓度与库区干流相近，二者的月变化趋势也高...
纳米银由于其独特的抗菌特性广泛应用于工商业领域.通过研究3种不同粒径和包裹物的纳米银对典型海洋微藻中肋骨条藻(Skeletonema costatum)的毒性效应,进一步丰富纳米银对藻类毒性效应及其作用机制的认识.结果表明3种纳米银对硅藻细胞生长都有不同程度的生长抑制效应,其毒性大小依次为10 nm-OA>10 nm-PVP>20 nm-PVP.在细胞毒性方面,相同粒径的聚乙烯吡咯烷酮(PVP)包...
