| This research makes use of the foundation between traditional hydrology geology, hydrology geochemistry and environment hydrology geology etc. comprehensive method last, combination number reason statistics learn to wait mathematics analysis tool, to city suburb area 1973-2003 years in Peking data the proceeding analyzes, adopting the 70's up to now of monitor the data enters water for certain the fluid matter index sign checks against value, pass to proceed to Peking City city suburb area cent distinction layer, usage application number manage the covariance, the software of Sufer and PIPER three line illustrated manual table the method proceeds to Peking city suburb groundwater fluid matter variety the regulation studies and the groundwater chemistry type divides into section.In groundwater pollution timespace that understand the foundation distributing the characteristic, pass to the environment geology term and the analysis of the groundwater fluid matter relation, combinative contaminative source characteristic, make use of the rock construction data, study the environment geology term take with the badose zone of groundwater the relation of the frangibility.This investigative work the scope is the city suburb area of Peking City, ising current with the city suburb inside the area the fourth department the groundwater fluid matter monitors the net orders the inside of 57 diving well,64 accept to press the well of water as the research object, with national " groundwater quantity standard " GB/ T14848 — 93 inside of Ⅲ standard for evaluate the index sign, to standard total degree of hardness, the ion of Cl- , sulfuric acid in item in normal regulations a nitrogen, second nitrate nitrogen, ammonia nitrogen, total deliquescence solid with sour salt in high manganese index number etc. pollution the factor proceed quantitative analysis research, make sure to the main and contaminative factor its present condition contaminative super mark scope.Make use of immediately after number reason statistics method, pass the PIPER three line illustrated manual table the method proceeds to Peking city suburb groundwater fluid matter variety the regulation studies and the groundwater chemistry type divides into section.Pass the analysis detection, study the area dive its water chemistry type the main regarding the type of Ca- Mg- HCO3 as principle.Have no too big variety on the space of the water chemistry type, the basic top regard the degree of hardness of HCO3- as principle, individual order with not carbonate degree of hardness is lord, water chemistry type comparison one.Moreover, the water chemistry type is rung by earth's surface reflection on water more obviously, SO42+ the Cl- contain the deal over 50%.Accept to press the water water chemistry type with Ca- Mg( Ca)- HCO3 is lord.Can see to have from the Piper third the line illustrated manual table a little amount point fall in the SO4+ the Cl contains the deal over 50%, the elucidation suffers earth's surface living dirty water with industrial waste water affect than obviously.The base watering path flow the characteristic to dive to take before with the variety regulation of the fluid matter index sign to the certain mountain, the plain dives the area, stability accepts to press the area of water and transitions take four areas to enter water differently the fluid matter index sign checks against the value, and regard this as the basis to study the city suburb area fluid matter the variety the regulation, thesis with 30 years monitors data for foundation, make use of GIS and the software of sufers, from the stereoscopic reaction in angle in timespace not the corresponding period groundwater the diving and accept to press the water degree of hardness, SO42-, Cl- of variety regulation.Pass the research, control to study the area inside the different mining the layer inside groundwater the pollution the characteristic, opposite degree, scope and trend, and main contaminative index sign an influence for of inside contact, understanding dif...
