| Abstract: | Objective]The research aimed to establish remote sensing extraction area model and growth monitoring of winter wheat and rice in Anhui Province in 2009.Method]The model was established by analyzing the planting structure,characteristic of phenological calendar,biological characteristic and characteristic of NDVI curve.Result]In temporal,the growth condition of both winter wheat and rice in Anhui Province varied as tendency of "better in fore period,worse in middle period and normal in later period".In spatial,the growth condition of winter wheat in northern Anhui Province was not well,and that of rice was not well in Chuzhou of Anhui Province.Conclusion]The study would provide an effective ways of obtaining crops planting structure for Chinese agricultural remote sensing monitoring system. |
