中文摘要	以贵州省花江峡谷石漠化治理示范区为研究单元,对比分析了小流域2005和2009年生态治理下的土壤理化性质与植物数量特征的变化。结果发现,该区土壤理化性质的变异系数值降低,说明土壤理化性质的空间变异程度降低;土壤总孔隙度略微降低,非毛管孔隙度明显增加,毛管孔隙度明显下降,土壤毛管持水量明显降低,土壤田间持水量明显提高,表明土壤的孔隙结构更加合理,土壤持水能力与通气透水性能增强;土壤有机质含量变化不明显,全氮、全磷含量明显增加,全钾营养元素含量降低,土壤pH值略微降低;植物的高度、基径、冠幅、均匀度等数量特征呈明显增长趋势,土壤质量与植物群落的生态效应具有较好的一致性。经过石漠化生态治理的土壤、植被生态效应改善与提高,逐步改善岩溶山区石漠化生态环境
英文摘要	The change of soil physicochemical property and vegetation quantity attributes in Huajiang canyon demonstration area of ecological management of rocky desertification in Guizhou Province during the period from 2005 to 2009 was analyzed.The results indicated that:(1)The coefficient of variation of soil physicochemical properties reduced,suggesting its spatial variation degree decreased.(2)The soil total porosity slightly declined; the soil non-capillary porosity significantly increased; the soil capillary porosity and the soil capillary capacity decrease markedly; the soil field capacity rose obviously,indicating that soil porosity configuration became more rational.(3)Change of organic matter content was not distinct.Total nitrogen and total phosphorus significantly increased but total potassium decreased.Meawhile,soil pH value slightly decreased.(4)The height,base diameter,crown diameter and evenness of plants increased prominently.The ecological efficiency of soil quality and plant community was preferably coherent.All above results illustrate that the soil and plant ecological efficiency have been improved,which ameliorate the environments in rocky desertification of ecological management areas in karst mountainous region.
