Based On The Evaluation Of The Arcgis Xi'an Ecological Civilization And The Countermeasures

Ecological civilization construction is different from traditional pollution control and ecological restoration, but to overcome the drawbacks of industrial civilization, explore the resource-saving and environment-friendly development path of the process. Xi'an ecological civilization has become a priority for sustainable development, an important and urgent task. GIS takes the fancy of the governments at different levels and administrations for its powerful processing function in space data. At present, GIS is being widely applied in land use, land improvement, city planning, traffic command, Water Resources and Hydropower, mapping, environmental protection. Take Xi'an for an example, with the powerful data processing, graphics editing, and spatial analysis of ArcGIS construction of ecological civilization workable theory for applied research, ecological theory and research is a distillation of great research value and theoretical value.On the basis of fact-finding works, collection and classification, holding a mass of first-hand accurate information, used the SWOT analysis method, from the strengths, weaknesses, opportunities and threats in four areas, ecological civilization construction of Xi'an conditions were the basis of analysis and evaluation. Then, the subject of using AHP method and the factor weight method, the establishment of an ecological civilization construction evaluation index system of mathematical models 4, application of genetic algorithm based on MATLAB software programming, computing, and GIS as the technical means to use its rich graphics editing, convenient and powerful database management systems analysis of spatial data processing, map out ecological civilization construction system of Xi'an various thematic maps on ecological civilization construction in Xi'an quantitative evaluation conducted for the evaluation of ecological civilization, Xi'an information technology provides the foundation and security. Finally, the issue raised the public school government and enterprises of ecological civilization "Four in One" concept model, ecological civilization construction in Xi'an, "four" in the adaptive analysis, and then from the drive mechanisms, constraints, mechanisms and guidance mechanisms the establishment of three ecological civilization construction of Xi'an "four in one" mode mechanism.Based on the study in Xi'an of ecological civilization construction, comes to some conclusions which are as follows: (1) Xi'an in 2004,2006,2008 construction of ecological civilization was evalua-ted on the whole, evaluation system, close to the standard value of the index, which shows that construction of ecological civilization is moving healthily and orderly in Xi'an. The green coverage, urban air quality,infrastructure construction have a more substantial increase in the last three years in Xi'an, although the standard values are still large gaps, but the gap is gradually narrowing, the construction of ecological civilization of Xi'an has a broad prospect.(2) This study was established the evaluation system of ecological civilization construction in Xi'an, the construction of ecological civilization Xi'an government enterprise students people "four-in-one" concept model and "Live" operation mechanism. Especially the evaluation system of mathematical models, quantitative calculation, previous studies of relatively rare, while Xi'an targeted construction of ecological civilization and the practice of reference value.(3) SWOT analysis method used in this issue of ecological civilization construction of Xi'an and basic analysis, objective, comprehensive, and accurate; application of AHP method to establish evaluation system of ecological civilization construction in Xi'an, and the application of genetic algorithm based on MATLAB software programming calculation, the calculation of advanced, high efficiency, accurate and reliable.(4) Using the geographic information system software tools—ArcGIS mapping and analysis of the powerful graphics capabilities, on the ecological civilization construction of Xi'an made a special mapping and analysis, construction of ecological civilization, Xi'an offers intuitive guidance and GIS expert analysis, to promote the message of ecological civilization, Xi'an construction.
