遥感信息量化处理在西昌地区构造解析及油气远景预测中的应用

该文从地质遥感信息定量分析着手、通过对遥感图像进行处理和信息提取, 新发现大量重要地质构造信息。并按不同构造层次对线性、环形构造等信息进行了量化处理, 进一步建立了研究区区域构造和重要构造区带遥感信息三维彩色量化解析模式。通过区域断裂系统量化解析, 确定了相对稳定的含油气构造地块和重要的构造区带; 通过重要构造区带遥感解译的环形构造及与其有成因联系的环状、放射状大节理的量化处理和定量解析, 确定了含油气局部构造。最后通过局部构造综合评价研究, 预测了含油气远景区。

STUDY ON THE RELATIONSHIP BETWEEN THE DECADAL VARIATIONS OF ANNUALLY FIRST RAINY SEASON PRECIPITATION OF GUANGXI AND SEA SURFACE TEMPERATURE OF INDIAN OCEAN IN SOUTHERN HEMISPHERE

Decadal circulation differences between more and less rainfall periods in the annually first rainy season of Guangxi and their association with sea surface temperature (SST) of the austral Indian Ocean are investigated by using the NCEP/NCAR reanalysis data. The results are shown as follows. A pattern in which there is uniform change of the Guangxi precipitation shows a 20-year decadal oscillation and a 3-year interannual change. In contrast, a pattern of reversed-phase change between the north and the south of Guangxi has a 6-year interannual periodicity and quasi-biennial oscillation. In the period of more precipitation, the surface temperature in Eurasia is positively anomalous so as to lead to stronger low pressure systems on land and larger thermal contrast between land and ocean. Therefore, the air column is more unstable and ascending flows over Guangxi are intensified while the Hadley cell is weakened. Furthermore, the weaker western Pacific subtropical high and South Asia High, together with a stronger cross-equatorial flow, result in the transportation of more humidity and the appearance of more precipitation. The correlation analysis indicates that the Indian Ocean SST in Southern Hemisphere is closely associated with the variation of the seasonal precipitation of Guangxi on the decadal scale by influencing the Asian monsoon through the cross-equatorial flow.
