Research on agricultural land suitability assessment based on GIS in Sichuan
Land suitability evaluation is the precondition for rational using and planning of land.This paper taking Sichuan province as study area,choosing five evaluation factors as altitude,slope,slope assured,water conditions,traffic conditions and so on,single factor was evaluated in study area respectively using ArcGIS software.Analytic hierarchy process (AHP) was introduced to calculate the weight of each evaluation factor.Spatial comprehensive analyzed on single factor evaluation analysis map according to the evaluation model,and then got the cultivated land suitability level distribution thematic map,and the spatial distribution of cultivated land and the proportion of the total evaluation area of Sichuan province.It provided scientific basis for land use planning in Sichuan.The research results show that using spatial analysis function of GIS with evaluation model to evaluate cultivated land suitability is one fast and feasible method.
