摘　　要：对黔中喀斯特石漠化地区17种植被恢复模式进行了石漠化率和植被盖度的季节性动态研究,结果显示:封育林5种模式的季节性石漠化率呈现先降低后上升的动态变化规律,纯林模式落叶树种的季节性石漠化率呈先下降后上升的趋势,混交林模式中季节性石漠化率均呈现先下降后上升的动态变化规律.The seasonal dynamics of rock desertification rate and vegetation fractional coverage for 17 modes of vegetation restoration in Central Guizhou was studied.The results showed that the seasonal rocky desertification rate of the 5 modes first rose and then dropped for the enclosed forests,and first declined and then rose for the pure deciduous forests and mixed forests.
