The following results are made from this research: Assessing data quality and band combination of different bands in line with geo-target features in desertification areas, and determining basic bands for desertification monitoring. And understanding and studying the spectral features and variation rules of geo-targets in the experimental area, raising that it is the basis of geo-targets information collection with imaging spectrometer data to understand spectral features and variation rules of geo-targets, realizing that in a great extent spectral-integrated-form-based classification method can remove the phenomenon of "different spectrum with same objects" resulted from reflection ratio curve translation because of the angle change among sensor, targets and observation direction, and the average and variance images can be introduced to solve the problem of two kinds of geo-target with similar spectral forms and much different values of whole reflectionratio. It is suggested that "red edge" range bands of vegetation, which has close relationship with vegetation cover and biomass, is the main characteristic bands and important basis for careful vegetation classification and quantitative retrieval, and pixel-based derivative spectral analysis is very useful for removing the effects of soil background values and quantitatively retrieving vegetation biomass and cover. The remote sense quantitative retrieval model is developed for main appraisable factors of desertification monitoring assessment with imaging spectrometer data and then the applicability of model is analyzed.

Data mining is an analytic skill that can analyze and find out the potential information among the original data and materials. Under data mining, the way used most frequently for prospecting original materials is decision tree of classification.According this divinable model, business can find out the relation between all attributes such as customers, products and regions etc, so that they can formulate some business management strategies like product-marketing base on these relations.

分类分析中的决策树是资料探勘技术中常被使用的一种资料探勘方法，依据已知的类别建立预测性模型，以解决类别之特性，企业可以根据这个预测性模型来找出客户属性、产品属性、地域属性等属性间的关联性，再利用这些属性间的关联性来订定产品行销等企业经营管理策略。

After reading and integrating lots of correlative science and technology books, the domestic and international research on CRM is summarized, and then the system frame is built. The conception of relative degree is proposed in the theory, which involves some methods in economics, such as the lifecycle curve of product or technology and the principle of time sequence, and so on. So the foundation for researching the system is built. Applying the technology of data warehouse and the correlative arithmetic of data excavating and method for classifying the clients, the resource analysis module is built,and the problem of data disposing and service management is resolved. The clear relationship of clients and sale strategy is obtained and the valuable client resource is grubbed up by analyzing the information of the clients. The enterprises will gain more clients and businesses opportunity, accordingly, the effect of less investment and more output.is attained.
