Statistical analysis and estimation method for regional cotton-rice rotation period by satellite remote sensing
How to evaluate crop rotation level in large geographic area is one of the most important problems in agricultural production.According to statistical analysis,a statistical model is built for computing crop statistics rotation period and evaluating crop statistics rotation level by interpreting two continuous-year crop satellite images.The initial results of this model application in Xinhua city of Jiangsu Province show that the period for cotton-rice rotation in this city is about 2.09 years.Therefore,against traditional rotation period,crop statistics rotation period and level is more accurate for crop rotation status in large geographic area.
