Abstract:

Building the evaluation unit with GIS technology, selecting the key factors of crop environment, and then use spatial cluster analysis to build the crop ecological suitability evaluation system. It has a good application in evaluation of crop suitability analysis, crop introduction regional analysis and characteristics crop area expansion. It has a guiding role distribution and adjustment of planting structure, with a strong scientific, practical and operational.
