Guyuan County diversion project, water is the source of life, is the material basis for human survival and development. However, due to drought and water shortage, is located in the arid and semi-arid mountainous southern Ningxia region's economic and social development are severely constrained in Guyuan County Cinder large crawler machine, but also more difficult to improve survival and quality of life. Along with social progress and development day by day, water scarcity and more prominent in Guyuan County, the demand for water more urgent. According to statistics tracked Cinder machine supplier, 10 years later, Guyuan county's population will increase to 15.6 million, the industrial output value of 10 billion yuan, the annual water demand of 23.3 million cubic meters Medium Track Cinder machine, if the current Guyuan county water supply inventory and annual water demand calculations, in another 10 years, 20 years, the county will be a serious water shortage. How to seize the western development opportunities in the development process, speedy completion of the county urbanization, water, and again become an unavoidable topic. East hillside construction diversion project is the only way to solve this problem. ? 巩义鑫 China is producing slag professional manufacturers willing to sacrifice power livelihood projects to this end! Heilongjiang Nen water conservancy project. River water diversion project environmental impact analysis is the construction of a very important research topic, with quite significant diversion project on the feasibility of the decision-making. In this paper, Nierji Hydro built to run as a precondition for the expansion of Heilongjiang Nen a project on the impact of the Nen River water environment were studied. The study includes: a project to predict the impact of the Nen River hydrological regime, a project the Nen River water quality impact analysis. Paper a numerical simulation model, developed by the Danish Hydraulic Institute's MIKE11 software for solving the model to predict the impact on the water regime; the use of comparative analysis method to evaluate the impact on water quality. By studying that: the impact of a project on the Nen River diversion of river runoff mainly by Nierji reservoir drainage control, the Nen River in downstream water flow has a relatively large change in the special dry years (p = 90%) of 8 , September and October, the Nen River diversion impact on hydrological regime is large, there is no impact of non-diversion period, Qiqihar Fulaerji section driest month flow to meet 35m ~ 3 / s river environmental water requirements; hydrological regime changes and increased irrigation return flows have a certain effect on the Nen River water quality. China is the production of slag 巩义鑫 professional manufacturers willing to sacrifice the power of livelihood projects to this end!
