Thirdly, it introduces the theory of the imagesegmentation and frequent segmentation technique. The aim of the imagesegmentation is to mark off the interested region of the image, which is done to thecorresponding image processing to reduce the operation time and save the storagespace. At last, it mostly introduces the compress technique based on the wedgelet, andcompares the CART model which is introduced by Donoho and the improved modelby Romberg et.al. with the model of the article, then compares the image ofprocessing based on the three methods.

然后，介绍了图像分割理论和常用的分割技术，图像分割的目的是划分出感兴趣的图像区域，进行相应的图像处理，减少运算时间和节省存储空间；最后，主要介绍了基于伸长小波压缩的技术，将目前主要的算法----Donoho提出的CART模型和Romberg等人基于此的改进模型，与本文所提出的算法模型进行了比较，并对三种方法处理的效果图作了详细的比较。

The level of feed-water and drain system is comparatively high in the history of China.The research on the level of agriculture in Han dynasty indicates that the prosperity of cities in Han dynasty is based on the tender agriculture and the food supplies import is a constant state in the study area. There is no breakthrough in level of agriculture after Han dynasty,and it is an important reason that the city development in the study area is fluctuant in the history of China.From the end of Han dynasty to North and South dynasty,the climate change made the cold and arid weather keeping in the study area,and affected badly the agricultural outputs.The mode of land-use was transformed from the agriculture to the nomadism in this stage.The climate change made the desertization develop mightily and fast,and approach the scale of modern time in the study area in the North and South dynasty.

研究区汉代农业生产水平的综合分析表明，一方面，汉代城市的繁荣是建立在比较脆弱的农业基础上的，粮食等物品不断的外部输入是一种常态，汉代以后很长时间粮食生产水平并没有突破性的提高，这是研究区城市发展呈阶段性起伏的重要原因；另一方面，南北朝时期冷干气候的持续，对脆弱的农业生产具有重大影响，农业向牧业迅速转化，城市的区域农业支持系统受到严重影响，该时期沙漠化也强烈发展。
