英文摘要	The characteristics of surface heat flow, which are the comprehensive reflection of lithospheric tectono-thermal evolution and a constraint on thermal history reconstruction, are of great importance for dynamics research and hydrocarbon resource assessment in sedimentary basin. 19 new heat flow values have been calculated based on the newly collected temperature data of the Pearl River Mouth Basin, among which, 12 heat flow data located in the deep water area (where water depth exceeds 300 m). The new data, which could make better control on heat flow distribution of the basin, is of great value since the rarity of the borehole heat flow in the deep water area. Together with previous studies, a heat flow contour map of this basin has been depicted and the distribution characteristics have been further analyzed. The lithosphere thickness at 36 wells also has been calculated by solving the one-dimensional heat conduction equation and then its relationship with the surface heat flow has been acquired. The results indicate that the surface heat flow values of the Pearl River Mouth Basin vary from 24. 2 to 121. 0 mW . m(-2), with an average of 71. 8 +/- 13. 6 mW . m(-2), and the average borehole heat flow in the deep water area can reach as high as 84. 5 +/- 4. 4 mW . m(-2). The heat flow value increases from the shelf area to the slope area while the lithosphere thickness shows an opposite trend. The relationship between the surface heat flow and lithosphere thickness can be expressed by an exponential function.
