摘 要:中国陆架沙漠的形成与大陆荒漠的形成都有一个统一的根本内因。古老沉积层的油气矿床中的碳氢化合物由于地壳运动而不断渗透、扩散、挥发。这些混合物的分子长期运动,透过泥层、砂层殃及植被,使植物污染枯萎。植被的破坏、消失是形成荒漠的关键。干旱、风成等等是同时伴生影响荒漠的外部条件。There is a common basic cause behind the formation of deserts on the China shelves and those on the continental inland. The hydrocarbon in oil and gas dep osits of paleo-sediments was in a state of constatnt penetration, diffusion and volatilization, due to the motion of the earth's crust. Because of their perpetual motions, molecules of these mixtures penetrated mud, sand, eventually reached the surface, bringing disaster to vegetation, polluting plants and withering them. The refore, the disappearance of vegetation due to the influence of hydrocarbon from underground was the key to the formation of deserts. Drought and winds etc. were external factors in influencing the growth of deserts.
