| 1. | Aquatic macrophyte vegetation 水生大型植物群落 |
| 2. | Aquatic macrophyte vegetation restoration in multipond wetland systems and its control on nonpoint source pollution 多水塘湿地系统中水生植被恢复及其对面源污染的截留作用 |
| 3. | Therefore , establishing and restoring the ecosystem mainly of macrophyte was the effective way to control the eutrophication of the west lake 因此,建立和恢复以沉水植物为主的生态系统,是治理西湖富营养化的有效途径。 |
| 4. | Standard guide for conducting static , axenic , 14 - day phytotoxicity tests in test tubes with the submersed aquatic macrophyte , myriophyllum sibiricum komarov 在装有浸入式水生大型植物狐尾藻属sibiricum蜀试验管里进行静态无菌和14日植物毒性试验的标准指南 |
| 5. | Although an order of magnitude smaller , the pore water pool can supply enough nutrients to build up the macrophyte biomass pool , but only if a fast turnover is attained 尽管数量级较小,孔隙水池可提供足够的营养来维持大型动植物的生存,但是需要周转得很快。 |
| 6. | These values were compared with the n and p concentration in sediments and macrophyte biomass in order to assess nutrient availability , fate and storage capacity 这些数值被用来与沉淀物和大型动植物中的氮磷浓度相比较,由此得出营养物质的有效性,去向和储存量。 |
| 7. | Macrophyte played important role in the distribution of fish community . biomass of fishes in the macrophyte regions was significantly higher than in the regions without macrophyte 水生植被是小型鱼类群落分布的主要影响因子,有水草的区域鱼类数量显著比无水草的区域多。 |
| 8. | Nh4c depletion in the pore water concentration and low n / p ratios ( 3 . 7 by weight ) within the macrophyte biomass at the end of the growing period suggest that available n limits plant growth 孔隙水浓度中nh4c的消耗和大型动植物生长末期的低氮/磷比率(重量上占百分之3 . 7 )表明,有效的氮元素限制了植物的生长。 |
| 9. | One of the sub - lake , the xiaonan lake area , after a series of control engineering had a large area of macrophytes , the transparency of the water was increased greatly and the density of algae was evidently decreased , and the water eutrophication character transformed gradually from phytoplankton type to macrophyte 西湖子湖之小南湖区经系列工程治理后,出现了大面积的沉水植物,水体透明度大大提高,藻量明显下降,水体富营养特徵逐渐从浮游植物响应型向大型高等水生植物响应型转化。 |
