Yangtze River Source Area Water Environment And Hydrochemistry Background Characteristic

Qinghai is called it “the Chinese water tank”, also is Yangtze River, Yellow River, LanchanRiver’s place of origin, the source area ecological environment status extreme is important, but theecological environment is extremely frail, in the area the water conservancy project link geologyresearch degree is very low, in order to better research and protects three river source areas theecological environment, this article has conducted more thorough research to the Yangtze Riversource area water environment and the hydrochemistry background characteristic, further knows theYangtze River source area the water environment present situation.And studies through the massivediagnosis, had the large scale enhancement to the Yangtze River source area hydrology and thehydrogeological conditions and the geological environment background level of understanding, thusfor studied and protects the Yangtze River source area area the ecological environment to providethe most foundational geological data.This article take the Yangtze River source area water environment present situation as theobject of study, through methods and so on investigation, sample, experiment and analysis, hascarried on the investigation and the appraisal to in the area surface water environment and theground water environment present situation, to the control area in the hydrology and environmentalfactors and so on hydrogeological conditions meteorology, hydrology, geology, structure has alsocarried on the elaboration, and has analyzed the Yangtze River source area surface water and theground water hydrochemistry background value according to the experimental material induction,has basically grasped the Yangtze River source area water environment and the hydrochemistrybackground characteristic, has yielded certain result.The Yangtze River source area waterenvironment and the hydrochemistry background characteristic strict controlled in the geologicstructure, the landform spot, the formation lithology structure characteristic and the climaticconditions and the ground water makes up a diameter row of condition the control. Tanghla sierrahills fluctuates the near thing to tower south the Yangtze River source area, the Kunlun Mountainnear thing to spans in the Yangtze River source area north, has formed north the source area thesource Qumar River basin, the source tuo Tuo River basin, the exceedingly high rivers territoryupside and south the source works as the tune river four big basins, and have formed the every largeor small more than11,000lakes nearby the intermont basin and the rivers.The rivers hydrochemistrycharacteristic is restrained factor and so on upstream lithological character, reach of stream, regionclimate, river water current capacity influences, the hydrochemistry type is complex, the hardness index compares Gao De not one, partial section of river performance for salty water river. TheYangtze River source area inland sewer hydrochemistry characteristic climate and the landform unitcontrol, is obvious on the hydrochemistry chart, the ground water from the military supplies area tothe excretion area, the hydrochemistry type from arrives simply complex, the hardness index fromlow to high, the water quality from the good variations, in a complete hydrology geology unit, fromthe bedrock mountainous area military supplies area to the valley land, the basin and the plateauregion of no relief excretion area hydrochemistry ingredient change and the landform, the lithicfacies belt change basic tallies.These research results have provided Yangtze River the source areainitial environment background condition, from now on might further study the Yangtze Riversource area ecological environment change in this foundation the situation.
