Influence On The Environment Of Tao River Water Project In Central Gansu Province

At present, with the dramatically increasing of pollution, the shortage of water resources is increasing of pollution; the shortage of water resources is increasingly obvious. Because the water for building the eco-environment is occupied, the aggravation of eco-environment can't be controlled. The fragile environment and the increasing pollution make the region lose. the balance of pollution resource ,environment, handicap the sustainable development of the central part of Gansu and Gansu province and affect the safety of flood prevention of the middle and upper reaches of the Yellow River ,and the improvement of eco-environment of northwest of china.By investigating, calculating and analogizing, the paper analyzes the infection on environment of the project with combining ration and generalization. The main contents will be discussed next.It investigated the status in quo about the environment, colleted the data about nature and weather, and research the problem on zoology and society. It also research the status in quo on water resource and analyze the reason.By the in-depth realization, the paper finds the main two aspects on environment of the project.The main advantaged aspect is clearly improving water lack, adding the quantity of water per capita, enlarging the ability of mining groundwater, improving efficiency of water work, creating the vantage for fathering environment. At the same time, the project will advantage the condition for agriculture work, enhance the income of farmer, relax the press on environment of population explosion.The main disadvantaged aspect is changing the topographic physiognomic, ruining the ground and the plant, perhaps creating land side, collapse and debris flow, the project rubbish and soil high-erosion and so on. Thus the new soil erosion appeared. After the project complete part of hillside irrigative area can create landsides, the loess tableland can appear collapsible loess widely. The Brooklet area's ground-water level can rise; some area can appear soil secondary Stalinization.Due to successful experience about fathering little watershed ,water and soil protection, building agriculture environment , the paper progress the measures on environment and bring forword viable ways on fathering and protecting environment.The results are the project will bring some disadvantaged infection on water environment during a period and in some parts. The bad aspects can be lightened maximum. At all, the project will improve water lack, increase water for environment, advantage the condition for agriculture work and advance the level of people living, resolve penury result by water lack, change appearances in the central of Gansu province.
