| 摘 要： | 为了探明石漠化地区不同尺度立地情况下植被恢复的潜力,在立地分类基础上,依据立地分类主导因子,采用模糊综合评判方法,评价石漠化地区植被恢复潜力。结果表明:立地类型区中,对植被恢复潜力的评价等级都存在,不能反映其差别;立地类型小区中,白云岩类型小区大多处于中等至强水平,石灰岩类型小区大多处于中等至弱水平,白云岩类型小区植被恢复潜力强于石灰岩类型小区;立地类型组中,上坡位类型组处于弱水平较多,中坡位类型组处于中等水平较多,下坡位类型组处于强水平较多,植被恢复潜力上坡位最弱,下坡位最强;立地类型中,顺向坡类型处于中等至强水平较多,逆向坡类型处于中等至弱较多,顺向坡类型植被恢复潜力强于逆向坡类型。石漠化地区植被恢复潜力整体处于中等水平。结论:该评价指标能够反映当地植被恢复潜力,评价方法客观准确,可为喀斯特石漠化地区生态重建提供技术支撑。

| Abstract: | In order to investigate the vegetable restoration potential of rocky desertification region in different scales of site,fuzzy comprehensive evaluation was used.The results showed that the evaluation grades which were present in site type area couldn’t reflect the difference.In site sub-areas,the type of dolomites sub-areas was at more than the middle level,which was contrary to the limestones sub-areas.The revegetation potential of the dolomites sub-areas was stronger than that of the limestones.In site type groups,most of the upslope,midslopeand and lowslope type groups were at the low,middle and strong level,respectively.Vegetation restoration potential of upslope was the weakest and the lowslope was the strongest.In site type,the bedding slope type was at more than the middle level,which was contrary to the reverse slope type.Vegetation restoration potential of the bedding slope type was stronger than that of the reverse slope type.In addition,the vegetation restoration potential of rocky desertification region was at a medium level.The evaluation results would offer a technological support to the ecological reconstruction of the karst rocky desertification region. |
