摘　　要：用构成指数、演替度、生态优势度、物种多样性指数等指标，比较研究了重庆缙云山风灾迹地恢复７年后群落状况。结果表明，人工恢复和自然恢复存在明显差异，自然恢复演替速度快，空间发育好，人工恢复物种多样性高。产生差异的主要原因是人工恢复栽种了大量针叶。A comparative study was made of the community situation of the storm-destructed slashes on the Jinyun Mountains after 7 years' natual or artificial restoration with the criteria of composition index, succession degree, ecological dominance and species diversity. Significant differences were observed between naturally and artificially restored communities: the former appeared faster in the speed of succession and better in spacial development while the latter was better in species diversity. Such differences were attributed to the fact that in artificial restoration a great number of coniferous and decidous trees were planted.
