英文摘要	Mean heat flows and heat Josses of the Northern and Southern hemispheres are calculated using degree 12 spherical harmonic representation of the global heat flow field (Pollack et al., 1993). Mean heat flows and heat losses of 0 degrees hemisphere and 180 degrees hemisphere, with median lines being 0 degrees longitude and 180 degrees longitude, are also calculated. The mean heat flow of the Southern Hemisphere is 99.3 mW.m(-2), significantly higher than that of the Northern Hemisphere (74.0 mW.m(-2)). The mean heat flow of 0 degrees hemisphere (94.1 mW.m(-2)) is also higher than the Value of 180" hemisphere (79.3 mW.m(-2)). The mantle heat loss from the Southern Hemisphere is 22.1 x 10(12) W, as twice as that from the Northern Hemisphere (10.8 x 10(12) W). The 16.9 x 10(12) W mantle heat loss from 0 degrees hemisphere is close to 16.0 x 10(12) W from 180" hemisphere. The hemispherical asymmetry of global heat loss is originated by the asymmetry of geographic distribution of continents and oceans. The asymmetric distribution of heat loss is a long-term phenomenon in the geological history.
