Based on above studies, some main conclusions were obtained as follows : 1 the diatoms forming mats in low latitude west pacific is"shade flora"diatom Ethmodiscus rex Hendey; 2 the sites found diatom mats are zone distributed, the direction is NW-SE and most distribute in the deep water area with flat seafloor, between 17°N～20°N and the water depth 4837-6150 m below Carbonate Compensation Depth (CCD 3) AMS 14C dates show that the sediments rich in diatom mats occurred during 16.0 ~ 28.6 ka B.P., which means the bloom mainly occurred in last glacial maximum, while there are not diatom mats deposits in other layers; 4 A total of 101 diatom taxa belonging to 40 genera had been identified from the 155 samples in the two cores WPD 03 and WPD 12, and the relative percentage of Thalassionema frauenfeldii are the highest, Thalassionema nitzschioides、Azpeitia nodulifera、Hemidiscus cuneiformis、Nitzschia marina take the second place.

14C年期间，即&勃发&发生于末次冰期最盛期；4在WPD 03和WPD 12两个岩芯共155个样品中共鉴定硅藻40属101种，且Thalassionema frauenfeldii的相对百分含量最高，Thalassionema nitzschioides、Azpeitia nodulifera、Nitzschia marina、Hemidiscus cuneiformis等次之，这五种硅藻占整个硅藻物种相对百分含量的85%左右，说明在该海域表层水体硅藻席沉积过程中，这五种硅藻最容易与成席硅藻在同时期的环境中生存，形成勃发；5MIS3期的晚期，该区域表层海水盐度降低，这有助于该区水体的成层化，从而使&树荫种&硅藻开始勃发，导致&秋季倾泻&；6末次冰期由于南极中层水北扩，南大洋中层水将富含硅酸盐的海水带入了研究区，即南大洋的&硅溢漏&作用，使该区域硅藻得以勃发，同时，铁输入的增多，可能也是造成硅藻勃发的主要原因之一。
