摘　　要：通过最近几年庐山科学考察,发现了乌龙潭岩石表皮构造,并对采集的冰碛石的变形特征进行了曲率计算和显微组构分析,岩石应力—应变规律表明其均是冰川作用的产物;基础地球物理测量资料的研究也表明,庐山断块山地是郯庐大断裂的南延部分,它的运动形式受鄱阳湖断陷盆地内部地堑—地垒构造系统的控制,第四纪冰期—间冰期气候变化与区域构造的升降程式具有一定的耦合关系.In the last few years, some scientific investigation for the Lushan region were found. Some new data of field and achievement of analysis were achieved. Author founded the epigenetic structure of rocks in Wulongtan（Wulong Deep Pool）, and those deformatic feature conducted the computation of ourvature and the analysis of microstructure for that collected the glacial drift rocks, they stress-strain lows have proved results of the glacial activity. By the earthic survey maked know basin research, the block mountain of Lushan are sourtherly elongate part of the great faults of Tanlu （Tancheng- Lujiang）, the graben-horst structic system controled them movement for under the down-warpde basin of Poyang Lake. In the climatic change of the glacial stage——interglacial stage of Quaternary Period, there are coupling relation with pattern of the elevation and subsidence in the regional structures.
