| With the aid of GIS software and Surfer software, air sculpture dioxide pollutant spatialdistribution characteristic of Yinan was studied. GIS is a tool combining the spatialinformation with the attribute in formation, the analysis result from GIS may be outputwith the form of graphics and report, will be more direct-viewing. Surfer software hasbeen used in seven mathematical models, each mathematical model has its relatedparameter establishment, through establishing parameter flexibly and the choosinglogarithm study model, each kind of type the isograms may be drawed up.Since the 1990s, along with on the international multitudinous GIS expert as well as theenvironment modeling has simulated the expert to integrate GIS and the environmentmodel important understanding, causes to obtain the unprecedented breakthrough in thisdomain research, and has obtained many practical values very big research results. Alongwith integrates GIS and the environment model carries on the resources, the environmentquestion research is unceasingly.Thorough, the GIS present oneself widely applies to meteorological, the hydrology andthe water resources, soil erosion, the desert, the disaster, the policy-making support, theenvironmental monitoring as well as the global change and so on many domains. In recentyears GIS and air quality model union application more and more many, (EPA) is mostremarkable by the American environmental protection bureau in this domain research. Inour country, the GIS technology more and more also many is applied to theenvironmental protection domain. Mainly discharges, the region atmosphericenvironment pollutant total quantity control, to the vehicle exhaust domain and so on bayenvironment merit energy region division modeling conducts the research using GIS,obtains some research resulted, pollution monitor data, in the statistical analysisfoundation, use above two kind of software has carried on the simulation analysis to theriver bank Nan county's air pollutant—sculptures dioxide spatial distribution, hasobtained the sculpture dioxide ground pollution distributed isograms, through obtains tothis chart analysis, in the river bank Nan county city ambient air sculptures dioxidedensity scope is 0.13—0.43 (mg/m3), in which pollutes a more serious region for thenortheast region and middle, simultaneously under the river bank. Nan county environmental monitoring station help, to have representative equivalenton-line the stationing monitor, According to the scene monitor data analysis equivalenton-line computation density error, its scope is 16.6%——24.8%. May see theequivalent line achievement chart basically through the above error analysis accuratecredible. According to the achievement chart analysis, may obtain the river bank Nancounty's air pollution condition quite to be serious, for solves this county air pollutionserious issue, and based on river bank Nan county's in 2015 the long-term plan, thisarticle proposed the alternative scheme, namely most underneath constructs athermoelectricity payment proportional to production in the river bank Nan county cityyear to year leading wind direction the power plant. According to plans to construct thepower plant the scale, the geographical position, constructs the region the atmospheremeteorological condition, completed after to this power plant the sculpture dioxidepollution condition to carry on the forecast, and drew up the river bank Nan county cityusing GIS and the SURFER software the sculpture dioxide density isograms. Through toplans to construct the power plant the analysis, after will obtain the power plant tocomplete substitutes the original multitudinous small point source, the river bank Nancounty city atmospheric environment quality condition is improved great degree, thispower plant to the county seat city sculpture dioxide density contribution value scope willbe 0.005—0.042 (mg/m3), after the superimposition sculpture dioxide densityenvironment background value 0.001, in the city ambient air the sculpture dioxide densityscope will be 0.006—0.043 (mg/m3), the entire city sculpture dioxide density will beable to achieve the national two levels of standards.Using the GIS software, and unifies in the SURFER software to atmosphere pollutantspace simulation analysis, obtains the result quite is direct-viewing, is advantageous forthe analysis comparison, through to the data analysis; realizes to the environment monitorand the forecast, simultaneously available in environment management, provides thedecision-making for the superintendent. May direct-viewing see through this system thepollutant the influence, after takes the corresponding measure the effect, has facilitatedthe environmental protection staff and the administrative personnel to the environmentgovernment and the urban planning decision-making reasonable analysis and theformulation.
