| 摘 要： | 针对干旱评价中指标选取的模糊性及采用单一指标评价存在的不足,选取9个代表站点的逐月降水观测资料,应用陈守煜教授提出的模糊聚类循环迭代模型,对浙江省宁波市2000—2009年的干旱程度进行评估。结果表明:当模型参数变化时,评价区域各年样本的级别特征值基本稳定于一个较小范围内,并且得到的结果与历史文献记载基本吻合,说明模糊聚类循环迭代模型在干旱评估中具有可行性与实用性。

| Abstract: | This paper adopted the theory of fuzzy clustering cyclic iterative model advanced by an professorchen to provide a solution to both fuzziness of index for selection in drought evaluations and some flaws in applying simplified indicator evaluation,by evaluating drought degree in Ningbo of Zhejiang province with monthly precipitation observational materials from nine representative sites.These findings suggested that:when model parameter changed,level eigenvalue of each-year samples in the region evaluated wa... |
