The Way

To solve the ecological deterioration problems of the medium and small reservoirs’ downstream areas caused by water interception, the ecological restoration technique for dam’s downstream area is studied in this paper. Based on the investigation and analysis of the current ecological environment of a medium and small reservoirs’ downstream area in Qingyuan county of Liaoning, the downstream minimum ecological flow, with which the ecological environment of downstream can connect to that of upstream, is calculated. In the way of drawing water above the dam and building underground dam, the minimum ecological flow for the ecological environment of the downstream area will be able to reach a level where the continuity of the ecological environment is maintained. Consequently the aquatic habitats and stream ecological environment of the dam’s downstream channel can be improved and recovered.

Abstract Volatile halogenated hydrocarbons (VHCs) attracted many attentions due to its toxic and persistent in the environment. In this research, a novel in situ ecological restoration reactor was applied to the degradation of VHCs in polluted river water. The optimized working condition adaptation of the in-situ restoration technique was evaluated through orthogonal tests. The experiments showed that when the water depth was 0.4 m, the HRT was 5d and the current velocity was 1 m/s, VHCs removal efficiencies could achieve favorable value. The CHCl3 CCl4, C2HCl3 and C2Cl4 removal efficiency could reach 70.27%, 70.59%67.74% and 81.82%, respectively. F test results showed that both HRT and water depth were significantly related to the removal efficiency of reactor. Besides, using underwater modulated chlorophyll fluorometer analyzed the rapid light curves (RLC) of plants in the experiment, which showed that the VHCs of damaged river was harmful to the physiological state of the plants. Moreover, the microbial community structures of fillers in the reactor were tested by high-throughput sequencing, the findings supported that the microbial community made a great response to adapt to the changes of environment of the reactor. The relative abundance of Rhodocyclaceae increased slightly, which hinted that it had good adaptability to VHCs in polluted river water. The research results confirmed that in situ ecological restoration reactor was an economical technology for removal VHCs in polluted river water.

<p>Due to the hard surface and the lack of necessary soil environment for vegetation growth, the rock slope protection and ecological restoration is one of the research focuses nowadays. In this paper, we proposed a flexible slope protection method based on the vegetation membrane to protect the rock slopes including river and road slope. The vegetation membrane is a kind of organic bags which is perfused by a mechanical equipment with plant seeds, soil, sand, vermiculite, rice husk, adhesive material, water retaining agent with water in a certain proportion, forming a suitable environment for vegetation growth. Then the membrane is fixed on the rock slope by the anchor bolt in different specifications and quantities according to the different slope conditions. The results show that the minimum proportions of total nitrogen, phosphoric acid, potassium in the vegetation membrane are 5%, 25% and 10%, respectively. The tension load of the anchor bolt can reach 50 ~ 100 kg in different lengths. The vegetation coverage rate on the rock slope by this method can reach more than 80% in three months and the rock slope is much more stable. Additionally, two demonstrations of different rock slopes protected by this technique are briefly described and the good control effects are obtained. It will provide a new method for protecting steep and rock slopes.</p>
