The system implemented forest fire model selection automatically and intelligently. BP artificial neural network model of forest fire model selection was build by treating forest fire environment data as inputting variable and treating appropriate forest fire model as outputting variable. At the same time, we studied the methods of acquiring and calculating data of inputting and outputting. The system implemented machine of model selection automatically based on dynamic data driven technology. We selected 72 items experimental data from historical forest fire records in Beijing to experiment and confirm the validity of model selection. It turned out that the reliability of model selection is more than 80 percent.

It transforms the subtractive image from RGB color space to SRG color space. The experiment shows that it is efficient to segment the shadow with the moving vehicles.Secondly, in the vehicle classification module, we process the subtractive image by the morphological filtering and connected component labeling, obtain the figure and position of moving vehicle, and decide the characteristic vectors.At last, two vehicle classifiers are designed, one is the RBFNN classifier based on fuzzy K-means clustering, the other is the RBFNN classifier based on immune algorithm.

在车型分类方面，首先对差分图像作形态学滤波和区域连通处理，得到运动车辆的位置和轮廓，根据分类标准提取出车型分类所需的特征向量，然后分别用两种方法设计出车型分类器，一种是基于模糊K-均值聚类的RBF网络车型分类器，另一种是基于免疫算法的RBF网络车型分类器，通过在相同环境下的实验对比分析，基于免疫算法的RBF网络车型分类器在分类准确性和速度方面都优于基于模糊K-均值聚类的RBF网络车型分类器。

In order to escplore the new models of cultivating in school, the essay tightly connects cultivating with teaching and research activities, based on developing teachers vacational level by modern information technoledge. Besides, during the process of founding the system of trainning teachers in school, we decide on our cultive target—promote the element educational reform by school internet, combing the facts of different schools. The cultive contnet should suit measures to different conditions, trying to synthesise and stress its practical function. When carrying out the cultive plan, we should sum up different models and explain its essence, steps and function so that we make the best choice. As to evaluational methods, we can take varied evaluational ways, including self-evaluation and evaluating each other by combination of fixing quality and quantity. At last, it is very necessary to found a special organization in order to form cultive web, make entire standarization, pay attention to develop resource and provide cultive guarantee.
