| Abstract: | In this paper,the index system on the appraisal of comprehensive agriculture technology level is setting up through thirteen indexes in five aspects,and its level of each province in China is computed by adopting the model of FA-SOM neural network.According to the results,its level is divided into five types,and this article analyses the level of agricultural technology and its internal differences in spatial pattern from the total features and local characteristics. |
