摘　　要：为了揭示我国亚热带地区废弃矿区的植被自然恢复演替序列,采用了"空间与时间相对等"的方法,选取了9个长江沿岸不同时期的废弃采石矿区的崖壁的植被状况进行了调查。结果表明:植被的恢复情况均与采石场废弃的时间呈显著相关性。在植被的早期恢复阶段,前3个优势科有菊科、蝶形花科、蔷薇科。大部分植物的定居与采石矿场在开采的过程中形成崖壁上的空洞与裂纹有关。大多数乔木可以直接到达并定居在崖壁上一些不规则的、微凹或微地形处,因此那里的植被能够演替到乔木阶段。To reveal the vegetation succession sequences of natural restoration on the abandoned quarries in Chinese subtropical area, the 9 sites of the abandoned escarpments in different times along Yangtze River were selected to survey vegetation by the way of ＂room age equalizing time＂. Results showed that the restoration circumstances were significantly correlated with a bandoned time of quarries. In early restoration stage, the anterior 3 dominant families were Compositae, Papilionaceae and Rosaceae. Most vegetation colonized on escarpments where some hollows and cracks were formed during exploitation. Many arbors could directly arrive and colonize on some irregular retuse or micro topography, so vegetation on escarpments could succeed from arbor.
