石泥堆裸露山体植物绿化生态效应研究

通过石泥堆类型裸露山体植物绿化研究，结果表明，以巨尾按、台湾相思、马占相思和东南爬山虎容器苗为种植材料，在石泥堆中采用挖穴整地、下客土并拌少量过磷酸钙的造林措施，雨天在石泥堆中“见缝插针”栽种，3年生各种植物保存率达85％以上，高生长量达4．8～7．3m；土壤理化性质得到较大改善；土壤侵蚀量下降了72．53％～88．15％，提高了保持水土的功能。石泥堆选用巨尾桉、台湾相思、马占相思和东南爬山虎植物绿化可在短时间内恢复山体植被和生态系统。

Landscaping Ecologic Effect of Vegetation on Exposed Hill with the Type of Stony Muddy Soil

Landscaping of exposed hill with the type of stony muddy soil was studied.Container seedlings of Eucalyptus grandis ×E.urophylla,Acacia confusa,Acacia Mangium,Parthenocissus austroorientalis were taken as planting materials.Afforestation measures of hole digging,replacing with out-soil,malaxating of SSP were adopted on stony muddy soil.Plants were planted by making use of every opportunity on stony muddy soil in rainy day.The result shows that preserving rate of 3-year-old plants reach above 85% and height growth can reach 4.8-7.3 m.Soil physical and chemical properties get greater improvement.Soil eroding amount decreases by 72.53%-88.15%.Function of soil and water conservation are increased.Selecting Eucalyptus grandis ×E.urophylla,Acacia confusa,Acacia Mangium,Parthenocissus austroorientalis on stony muddy soil can restore vegetation at the mountain and ecosystem within short time.
