以泰安市大汶河拦蓄枢纽2号橡胶坝为例，针对橡胶坝建成后上下游河岸水土生态环境变化，采用工程辅助 + 生物两栖植物模式营造河岸、河坡和库湾植被生长的土壤环境；选择适生两栖植物进行造林复绿；打造新的水环境景观系统进行水土生态修复。实践表明，上述方法对营造和维护河岸水土生态系统、保护水资源和水环境具有良好的效果。
The paper took Tai’an Dawen River No.2 rubber dam as an example. According to the changes of soil and water ecological environment after the completion of the rubber dam, soil environment of the river bank, the river slope and the bay for vegetation growth was built by using the engineering aided and biological amphibious plant pattern. The suitable amphibious plant was selected for recovery of green and a new system of water environment landscape was created for water and soil ecological restoration. The practice showed that the above methods have good effects on creating and maintaining riparian water and soil ecosystem.
In this paper, the dynamics of polymer surface and its interior are measured by using fluorescence correlation spectroscopy with the SR dye molecules as optical probs. It is found that there are the anti-correlated characteristics to the orthogonal polarization of single molecules fluorescence when the SR molecules are absorbed onto the PMMA surface. It is presented directly that the rotational dynamics of the polymer surface is revealed by the cross-correlation function, and the rotational time is measurement. Accordingly, the molecules embedded inside the polymer film are restricted by the surrounded environment and have low rotational freedom degree.
