| Abstract: | Based on the techiques of GIS,overlay analysis was used to determine evaluation unit by the administrative map,soil map and land use type map,selected eleven influential factors from three aspects,of soil physical and chemical properties,profile characters and site conditions,established the evaluation system and model of farmland productivity,The methods of Analytical Hierarch program（AHP）,Fuzzy Mathematics Theory（FMT） and Integrated Index were adopted to synthetically evaluate the farmland productivity.The results showed that the basic cultivated farmland of 71 079.3 hm2 in the whole county was divided into 5 grades,and this paper conducted comprehensive evaluation of the cultivated land fertility.The results were well in line with the local situation and the approach was feasible and effective in cultivated land fertility assessment. |
