Abstract: Aiming at the inconsonant of agricultural mechanization zoning and its evaluation method at present with sociological and economic development, an agricultural mechanization zoning system, which creates a more direct and visual way for the Agricultural Mechanization Zoning, based on GIS, was lodged and built with the help of map objects employer technology. This system can process agricultural mechanization zoning and class by building geography information database, agricultural mechanization information database, and statistic process data and calculated zoning value. And by using GIS technology, the system overcomes the defects that zoning depends too much on labor work and the zoning results are not visual and realizes the visualization of the results. Applying it to classifying and analyzing the development levels of agricultural mechanization in all parts of Zhejiang Province, it provides a scientific theory for all governments to find out the development levels and characteristics of the agricultural mechanization in every area. The results show that this agricultural mechanization zoning system can easily and scientifically make zoning, and can also analyze sensitivity of each factor to the zoning results, and serve as a new method for agricultural mechanization zoning.
