[A comparative study on life-form spectra of evergreen broad-leaved forest in different successions in Jinyun Mountain].
The life-form of plant communities in different succession stages in Jinyun Mountain was studied and the life-form spectrum was established. The results showed that according to the characters of life-form of plant communities, the vegetation in Jinyun Mountain belonged to typical subtropical evergreen broad-leaved forest vegetation. Evergreen phaenerophytes were absolutely dominant in the life-form spectrum and its quantity accounted for more than 80%. Among phaenerophyte, quantity of microphanerophyte was the most, and quantities of mesophanerophtye and nanophanerophyte were less. Different successions had different life-form spectra. With the development of succession, the percentage of phaenerophytes increased, and other life-forms decreased correspondingly. According to the development of life-form and comparative analysis of environmental factors in different succession stages, coniferous species would be replaced by evergreen phaenerophytes.
