A comparative study of pollen floras between two cores: Core 17940 from the northern slope of the South China Sea and a core from the Toushe Basin in central Taiwan Province, reveals that there were three different vegetation types around the two areas during 15-40kaBP. The first type is characterized with the subtropical evergreen broadleaved forest during MIS2 (20-15kaBP). The second is the Pinus/Alnus-dominated woody plant communitites, corresponding to an interstadial summer monsoon dominated warm and humid climate and higher sea/lake level. The third is the Artemisia/Poaceae-dominated herb communities, corresponding to a stadial winter monsoon dominated warm and dry climate and lower sea/lake level.

Jianghan Basin is a representative inland salt-lake fault basin with an unique structural evolution history and petroleum geologic conditions. More than forty years of exploration activities have found over a hundred millions of proved reserves in place, and nearly two thirds of hydrocarbon resources to be proved. With the increasingly maturative exploration, the exploration direction research should be done as soon as possible.

江汉盆地是我国东部一个典型的内陆盐湖断陷盆地，具有十分独特的构造演化历史和成藏地质条件，经过四十余年勘探已经发现一亿多吨探明石油地质储量，还有近三分之二的油气资源待探明，随着勘探程度提高，勘探方向亟待深入研究。

Results The diagenetic grade of Permian rift basin was quite high, and the mechanical compaction resulted in the great loss of the original pore. The eodiagenesis and telodiagenesis were important to the reservoir, and fractures were the dominant hydrocarbon migrating pathway and accumulating space; In Triassic-Paleogene Formation, mechanical compaction was as important as pressolution, and the most original pore was preserved. The exodiagenesis stage of late hercynian movement, indosinian movement and Yanshan movement played the vital role in the diagenetic evolution and hydrocarbon migration and accumulation of the basin. The argillaceous dolomite and algal dolomite discaved in Permian, which were formed probably by hybrid process in high salinity lake which had the fresh water interfused in.

结果 二叠纪裂谷盆地的成岩强度大，以机械压实作用为主，原生孔隙丧失多且早，晚期成岩作用较重要，裂缝是油气运聚的通道和空间，可出现次生孔隙发育带；三叠纪－古近纪拗陷盆地的成岩作用表现为机械压实和化学压实作用并重，原生孔隙多被保留；晚海西、印支、燕山运动等表生成岩阶段对该区的成岩演化和油气运聚起到重要作用；二叠系中特征的泥云岩和藻云岩可能是在有淡水注入的较高盐度湖泊中经混合作用而形成的。
