The quality of water is reflected by the chemistry characteristic of groundwater, and the drinking safe correlate to local people's healthy, so it is necessary to carry on a chemistry characteristic of groundwater research. This dissertation analyses the date of shallow and deep groundwater of akesu region,opening out the tridimensional chemistry characteristic of akesu region.and then,Carrying on an analysis to the formation reason of it's chemistry characteristic.Based on the water quality datas in Aksu region, according to the inside relation of of degree of hardness, TDS, chloride and vitriol etc., calculate milligram equivalent value of each ion in water, and make a preparative for next writing work, then adopt shorclife method to classificate this area's water chemistry type.In the text applied the SUFFER 3D draw function to carry out the contrast. Exhibit the TDS's space variety of level direction. For resolving cross section can reflect only a point's vertical variety, In the vertical research, introduce a method of 16 kinds space mode sketch, then it can obtain two sets of space variety information. applicating comparison coefficient method during the research of specially area to analysis dissolves or filter degree,evaporate degree and calcium sodium ion's source,then get a conclusion.In the research of pH and each ion's plus or minus relativity research,Convert the quality density into 100 milligrams per litre, then make new density and pH as two sets of Y axial value, with the kind order serial number for X value, according to the trend line of alignment whether consistency, fix on pH and ion's plus or minus relativity, Then analyze TDS and each ion's curve relativity, thereby get a conclusion of pH's influence for water chemistry characteristic.The dissertation is mainly divided into four parts, from the chemistry characteristic tridimensional distributes to it's formation reason.The first part research for tridimensional distributes of groundwater chemistry characteristic,which includes characteristic of TDS,each ion,water chemistry type,and pH distribute characteristic.The second part is other factors which include the influence of chemistry characteristic formation, and study a contents to includes PH and each ion of their plus or minus relativity analysis, each ion and TDS curve relativity analyse, and then get a indirect influence from PH to groundwater chemistry characteristic.The third part analyses formation reason, and it's divided into 3 steps, first:studying on the formation reason of general structure of chemistry characteristic in Aksu region. Second, According as geography and TDS distribute characteristic, from the mountain the desert,it's mainly divided into three biggish districts, alluvial cataract plain area, alluvial river plain area and northern desert deposition area, then analysis each formation reason. Third, Analyze each unit and special district formation reason, concretely analyze to each research unit, and use a proportion coefficient method to analyse the formation reason of the special district.In addition, mankind's activity is also a factor which influences the groundwater chemistry characteristic formation.The fo(?)(?)h part is concrete conclusion of this dissertation.
