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)。

These two drought characteristics are considered for regional drought frequency analysis in this study. The L-moment based discordancy, heterogeneity, and goodness-of-fit measures are used to detect the unusual sites and select the regional probability distributions of droughts.

The results showed that there existed significant difference in chlorophyll a, MDA and proline content among different treatments. No significant physiological variation was found in electrolyte exosmosis percentage, POD activity and proline content between the salt treatment and the control during the treatment while the parameters in drought and salt/drought treatment fluctuated remarkably.

结果表明：欧李的叶绿素a、丙二醛和脯氨酸含量在不同的逆境处理间差异显著；碳酸盐处理的电解质外渗率、POD活性、脯氨酸含量等生理指标变化平缓，与对照差异不明显；干旱处理和盐与干旱协同处理的各项指标波动很大。

The main purpose of this paper was to explore the methods of drought tolerance evaluation,and to evaluate the relationships between some agronomic traits and physiological indicators with drought-tolerance in foxtail millet.

探讨作物抗旱性分析评判的方法，对谷子主要农艺性状和部分生理指标与抗旱性之间的关系进行综合评价。

As a result, germination rate under osmotic stress and RWC could be considered as good indices of drought tolerance and used for rapid evaluation for drought tolerance of foxtail millet.

谷子种子在甘露醇渗透胁迫条件下的相对萌发率与幼苗在适度控水条件下相对含水量的变化趋势一致，初步认为这两个指标可以作为苗期快速鉴定谷子抗旱性的筛选指标。

I. triloba of Group II possesses some potential useful genes of drought-tolerance, and root rot and other fungous disease resistance. It can grow under the condition of extreme drought and absolute wetness.

Basesd on the precipitation difference in Tsaidam Basin of Qinghai Province, three sampling areas, including Geremu, Delinghan and Doulan, were selected, and then three sapmling plots in each sampling area were selected to study the characteristics of plant community which dominated by Ceratoides lateens, Nitraria tangutorum, Tamarix chinensis, Kalidium gracile, Haloxylon ammodendron and Salsola arbuscula respectively. At the same time, the morphological and physiological features of above-mentioned 6 species were measured for probing their drought tolerance. By using the subordinative function method, grey correlative degree analyse and no-weight index comprehensive evaluation method, their drought tolerance were compared as well. The results were showed as follows: The main xeric vegetation types in the desert steppe of Tsaidam Basin were Nitraria tangutorum community, Tamarix chinensis community, Haloxylon ammodendron community, Kalidium gracile+Salsola arbuscula community, Ceratoides lateens+ Haloxylon ammodendron+Kalidium gracile community.
