Research On Design Of Soil And Water Conservation In Channel Management

River is an important part of urban ecological system, channel management is an important task of urban construction. The practice of a large number of river regulation in China in recent years, is used for the river channel improvement project is dig broaden the form such as dredging, realize the recovery of the flood and draining water navigation functions such as, to effectively improve and make the surrounding environment and ascend. However, high intensity of urban development activities on the urban river ecological environment caused great influence, most of the channel improvement project pay more attention to the subject protection, less attention to the influence of the soil erosion aspect, the principal part of the project already cannot form effective protective system, the soil erosion problems caused by the channel improvement project has become one of the highlights in agro-scientific research in the closely watched.Tianjin in accordance with the water, because of water and, according to the engineering overall arrangement of the beautiful Tianjin no. 1, Dongli river regulation project is Tianjin(2011-2020) of the total programming of the drainage plan management an important part of the river, river dredging Dongli Desilting governance, the construction of sewage pipe trunk pipeline engineering and sewage system, thus effectively improve Dongli district sewage treatment, improve the water environment, to ensure reach Tianjin government around four district wastewater treatment rate of 90% for two years and backbone river water clear goals. The project engineering for the construction project, the project area belongs to the Tianjin focus on soil and water loss prevention reserve, research on the project to carry out the design of soil and water conservation are typical and representative.This article through to the Dongli river regulation engineering of soil and water conservation scheme design research, through to the construction of the project may cause system of soil and water loss and its hazards analysis forecast, prevention and cure measures to rationally designed, determine the construction schedule, and put forward the monitoring requirements, makes every effort to minimize the project area of soil and water loss and improve the project area and the surrounding ecological environment, to ensure safe operation after the completion of the project, achieve win-win purpose, production and construction and environmental protection to improve river landscape, improve the regional ecological environment, promote the city’s economic and social sustainable development, has the important practical significance. At the same time, further exploration on the design path for soil and water conservation in channel improvement project will not only provide technical support for the full implementation of soil and water conservation in production and construction projects in Tianjin, but also set good examples for the accumulation on practical work experience in this field, and much more importantly will benefit the decision-making of the administration and the management of enterprises in the long run.
