对皮尔逊Ⅲ型分布公式中伽玛函数的计算问题进行了研究，提出了一种新的数值逼近方法，在一定范围内对伽玛函数用圆锥曲线表示，利用递推公式扩大参数范围，免去了数值积分和用级数展开计算的麻烦。

The Technological Support of Diversification Management Paterns Agriculture insurance zoning is essential to providing crop insurance scheme in Chinese agricultural. Six risk indices, indicating regional characteristics, and fuzzy cluster analysis method, are applied to divide risk zones. After that, three kinds of ratemaking of agriculture insurance ways are discussed,including the weighted average method, the normal distribution method and the Pearson distribution method.

第六章多元化经营模式的技术支持农业保险区划是农业保险经营过程中必要的基础工作，根据区划的要求，本章选择了六项最能反映区域特征的风险指标，运用模糊聚类分析法，进行农业保险的分区；提出了农业保险费率厘定的三种方法，包括加权平均法、正态分布法和皮尔逊函数法。

Firstly, Dempster-Shafer is developed by not only considering the certainty of the evidence, but also considering the average support of the evidence to different subsets in the assignment framework so that it can give more reliable combination result. Secondly, amplitude ratio feature and Euclid distance of the probability density distribution function in Pearson graph from different temporal SAR images are extracted to present change feathers in different scales. Finally, the improved Dempster-Shafer algorithm is applied to fuse the two different features to detect change information of SAR images.

首先通过综合考虑证据本身的确信度和证据对辨别框架中子集的平均支持度进行证据间的加权合成，改进证据理论对证据的合成，提高其可靠性；然后提取不同时相图像间的散射幅度的对比度和概率密度分布函数在皮尔逊图中的欧式距离，两种特征参数代表了像元级和区域级不同空间尺度下微波遥感图像中关于地表变化的信息；最后将改进的证据理论用于两特征之间的融合处理，得到地表的变化信息。
