In this article made the cluster of phonological type by 4 of main phenophase with bourgeon period, leaf expansion period, flowering period and fruit ripenes period of observed data on phonology of 42 kind of plant 34 year in Minqin desert area, further the 23 of phenology classification merged by phonological type.

本文以民勤荒漠区42种植物34年的物候观测资料，以萌动期、展叶期、开花期和果熟期4个主要物候期进行物候型聚类，进而将物候型归并为23个物候类型，聚合的物候类型基本上遵从植物的生态型特征，较系统聚类法直接用样本聚合的类型更加科学合理。

In this article made the cluster of phonological type by 4 of main phenophase with bourgeon period, leaf expansion period, flowering period and fruit ripenes period of observed data on phonology of 42 kind of plant 34 year in Minqin desert area, further the 23 of phenology classification merged by phonological type. The 23 of phenology classification basically obeys the ecotype characteristic of the plants, and the more scientific than the type of system cluster by plants sample. Moreover, the form of phonological type record by "ten day period + phonology" in the article.

In doing so, we have gotten these objects:(1)built the relationship between natural vegetation pattern of china and the climate,based both on Kira-index and dry/wet index;(2)built the phenology model describing main natural vegetation types of china,based on degree-day;(3)built the drought sensitivity function for main vegetaion types of china; and (4)integrated the drought sensitivity function with the PDSI.

在执行过程中我们基本上按照项目计划书的原初设计完成了如下的工作：①采用Kira的生物热量指数与生物干湿指数相结合的思想，建立了中国自然植被的空间分布与气候因素之间的数量关系；②利用有效积温与生育期之间的关系，建立了自然植被主要类型的物候模型；③根据文献中的实测资料建立了主要农作物类型、自然植被主要类型的缺水敏感性指数；④将此缺水敏感性函数代入Palmer干旱强度指数的计算模型之中。新的干旱强度指数计算步长为周(7天)。
