Ecological Techniques Discussion In Administering Zi River Engineering

This paper has elaborated domestic and international latest advance in water environmental construction and administering rivers concepts on the foundation of investigation research .On the other hand, the paper has researched and discussed a series of ecological technical problems in administering Zi river of Zi city section combining with the practical conditions of project district systems.Administering Zi river is a systematic project, is also a ecological project, which is concerned with the special fields such as environment, water conservancy , garden program, and so on. This project, on the foundation of investigation analysis, determines the basic train of thoughts by ecological administering, has determined near-period administering goal of water sources and water quality about river lake landscape. Based on landform and geological conditions, the author have put forward sewage disposal recycling scheme adopting compound earth layer to carry out land filtrate, under conditions of satisfying the preventing flood ability, comprehensively through considering water conservancy function, resource function, environmental function, ecological function, and carry out reasonable analysis and demonstration for the scheme. The author has carried out trial research and analysis on the efficiency and the purification effect of water quality by land sieve, and estimated the sewage disposal effect of artificial wetland; it has turned recycling water of landscape into reality, Around the theme of ecology, determined some correlative engineering technique-measures, such as seep prevention, the form of bank revetment, and so on, building Zi river ecological park by using two bank beach lands, all these is to reach the global objective of ecologically administering Zi river.Through the research of project ecological technology in administering Zi river, from the water quality analysis of water source and test research and application analysis of the sewage disposal system, the ecological project design of river course, and so on, the author attempts to explore a set of city water environment administering patterns that accords with reality, offer references for similar project. And the author hopes that the set of patterns can be popularized and produce larger benefits.
