Based on the analysis on the character of MPDI, the relationship between NDVI and MPDI is studied, and the threshold value of MPDI under densely vegetation covered, middle vegetation covered, sparse vegetation covered and nudation are built. MPDI＞0.12 means the surface is desert,sand or rocks; 0.01＜MPDI＜0.12 means the sureface is covered by middle vegetation, and MPDI＜0.01 means the earth is covered by densely vegetation. 4. Based on the expirical model relation between MPDI and vegetation optical thickness, the latter is computed by the modified algorithm.

对中、美、澳三国AMEX试验期间&向阳红5号&定点观测到的气象和海洋资料分析得出：①台风形成前，大气整个中、低层空气湿度较大，台风一旦形成，大气湿度最大层主要集中在中空；②风速垂直切变小，对形成台风是一个必要条件，但并非整个对流层风速切变都小，而且不同地区形成的台风，风速切变状况是不同的；③厄尔尼诺年南半球与北半球对应位置同期的θ_G、θ_8、Q_b相差不大，但是南半球的θ_c较北半球的大。

The extinction or appearance of these Ostracoda always occurred in a short time interval, and can be correlated locally and globally, so they are of importance in bioeventstratigraphy. This article listed six such biological events in Qaidam Basin and discussed their causes. The extinction of Cetacella reflected temperature decrease at global scale and changes of palaeoclimate zones during the latest Jurassic and the earliest Cretaceous; The rapid decline of Cypridea in the earliest Cretaceous may be a result of the strikes of small planets; at the latest middle-Eocene Austrocypris became extinct, and at Oligocene Hemicyprinotus disappeared. These events related to the changes of the geological conditions at that time. The explosion of Cyprideis at the middle-Miocene was because the rise of Qinghai-Xizang Plateau which resulted in the dry climate and development of salt lakes.

这些水生生物的绝灭或发生均很迅速，在区域或全球范围内均可对比，具有生物事件地层学意义：Cetacella属的绝灭可能是侏罗、白垩纪之交全球性的古气候降温和气候带变化在柴达木盆地的反映；早白垩世之后Cypridea的迅速衰退是地外因素灾变的结果；中始新世晚期的Austrocypris的绝灭、渐新世Hemicyprinotus的绝灭都与当时地质条件的改变存在著内在的联系；中中新世Cyprideis的爆发推断是青藏高原隆升，导致气候乾燥、湖水咸化的结果；而晚更新世晚期1。
