The Yongding River is the mother river of Beijing. However, due to the environmental pollution caused by economic development, the water and coastal environment of this river has suffered from great destruction. The ecological restoration of the Yongding River is imperative. Phytoremediation and microbial remediation have made certain achievements in the aspect of river pollution control, but both have their own advantages and disadvantages. How to make best use of their respective advantages depends on the collocation and combination of plants and microbes. Based on field research and former literature, we proposed the method of plant-microbe associated bioremediation to restore the water environment and remove heavy metal pollution in soil of the Yongding River. This attempt provides new ideas and methods for the restoration of the ecological environment of the Yongding River.Keywords

Based on the one-dimensional water quality modelling theory, this paper discusses the impact of different calculation methods on water environment capacity in different water functional areas. Through a case study of the Yinma River in Jilin province, in the same condition, the influence of four calculation methods (1. section-beginning control and no pollution sources generalization; 2. section-beginning control and uniform pollution sources generalization; 3. section-end control and no pollution sources generalization; 4. section-end control and uniform pollution sources generalization) on the calculated results of water environment capacity were analysed. The calculation results of four calculation methods from big to small are: 4,3,2,1. In the case of considering only one of the model parameters, control section or pollution source generalization, the percentage improvements of water environment capacity are the same.Keywords

Karst water is an important element of underground water in Beijing and is characterized by abundance of supply and high quality. Karst water is an ideal water source for alleviating the supply and demand discrepancy of water resources and providing water for the city. The water environment of karst landforms is relatively fragile and requires additional attention. So the rational use of karst water requires the establishment of scientific and effective models of water quality evaluation. Taking several karst water distribution areas as examples, this study established an index and standard of estimation according to set pair analysis (SPA). The study subsequently built the corresponding connection and determined the weighting factor according to the degree of association. Basic indicators of water quality were processed and analyzed through comprehensive evaluation principles to provide a foundation for the actual management and the rational use of karst water distribution areas in Beijing.Keywords
