| 摘 要： | 风作为大气流场活动的表现形式，是一种重要的地质营力，风场对沉积体系的展布有着重要的控制作用。风不但本身具有侵蚀、搬运和沉积的能力，形成风成沉积，它还可以向水体传输能量和动量，产生波浪和风生水流，侵蚀基岩、改造已有的沉积物，形成独特的沉积体系。以风场对沉积物的直接作用和间接作用为依据，将风场作用下的碎屑岩及碳酸盐岩沉积体系进行了分类:背风体系、迎风体系及侧风体系。风场概念的引入，为解释沉积体系（包括油气储集体）形成及预测其分布提供了新的视角，也完善了古气候学中古风场的恢复。

| Abstract: | Wind is an important geological agent as a form of the activity of atmospheric current field. It plays an im-portant role in controlling the distribution of depositional systems. Wind has not only the ability of erosion,transporta-tion and deposition developing the eolian systems, it can also transfer its energy and momentum to water creating waves and wind-driven flow developing unique depostional systems. In this paper, the clastic and carbonate deposi-tional systems influenced by wind field are classified on the basis of direct wind impacts and indirect impacts on sedi-ments:Leeward System,wind system and crosswind system. The introduction of the concept of wind field provides a new perspective for explaining the sedimentary formation(including oil and gas reservoir)and distribution as well as predicting sedimentary systems. It also helps improve the paleo-wind-field and paleoclimate reconstruction. |
