以广西平果市龙何喀斯特生态重建示范区为背景，比较其自然封育区不同类型微地形的形态特征、土壤理化性质及潺槁木姜子〔Litsea glutinosa (Lour.) C. B. Rob.〕叶片性状。结果表明：桂西南喀斯特石漠化山地微地形主要有石面、土面、石沟、石窝和石缝5种类型，面积占比的平均值分别为59.3%、24.1%、9.6%、6.3%和0.7%；同一类型不同单元的长度、宽度和面积变异较大。石沟、石窝和石缝的土壤含水量显著（P＜0.05）高于土面和石面；土面土壤容重显著大于石窝和石沟，最大持水量、田间持水量、毛管持水量、毛管孔隙度、非毛管孔隙度和总孔隙度显著小于石窝和石沟，pH值及有机质、全N、全P、全K、全Ca和全Mg含量均最低；石缝土壤pH值及有机质、全P、全Ca和全Mg含量最高，石面土壤全N和全K含量最高。石沟中潺槁木姜子单叶面积和单叶干质量显著大于土面、石窝和石缝，石缝中潺槁木姜子比叶质量显著大于石窝和石沟，土面中潺槁木姜子叶片全C和全Mg含量最高，石沟中潺槁木姜子叶片全N、全P、全K和全Ca含量最高。综合分析结果显示：受不同类型微地形的形态结构和土壤组成的影响，桂西南喀斯特石漠化山地的土壤理化性质和潺槁木姜子叶片性状具有较为明显的微地形分异特征，在该区植被修复中，应根据不同类型微地形的土壤环境特点有针对性地采取自然封育和人工促进修复等措施。

 Taking Longhe Karst Ecological Reconstruction Demonstration Zone in Pingguo City of Guangxi as background, morphological characteristics, soil physicochemical properties and leaf traits of Litsea glutinosa (Lour.) C. B. Rob. in different types of microtopography in its natural sealing area were compared. The results show that there are five types of microtopography namely stony surface, soil surface, stony ditch, stony nest, and stony crevice in karst rocky desertification mountain of southwestern Guangxi, and their mean percentages of area are 59.3%, 24.1%, 9.6%, 6.3%, and 0.7% respectively; the variations of length, width, and area of different units of the same type are relatively large. Moisture contents in soil of stony ditch, stony nest, and stony crevice are significantly (P<0.05) higher than those of soil surface and stony surface; soil bulk density of soil surface is significantly larger than those of stony nest and stony ditch, while its maximum moisture capacity, field moisture capacity, capillary moisture capacity, capillary porosity, noncapillary porosity, and total porosity are significantly smaller than those of stony nest and stony ditch, and its pH value and contents of organic matter, total N, total P, total K, total Ca, and total Mg are all the lowest; pH value and contents of organic matter, total P, total Ca, and total Mg in soil of stony crevice are the highest, and contents of total N and total K in soil of stony surface are the highest. Single leaf area and single leaf dry mass of L. glutinosa in stony ditch are significantly larger than those in soil surface, stony nest, and stony crevice, specific leaf mass of L. glutinosa in stony crevice is significantly larger than those in stony nest and stony ditch, contents of total C and total Mg in leaf of L. glutinosa in soil surface are the highest, and contents of total N, total P, total K, and total Ca in leaf of L. glutinosa are the highest in stony ditch. The comprehensive analysis result shows that soil physicochemical properties and leaf traits of L. glutinosa in karst rocky desertification mountain of southwestern Guangxi have evident microtopographic differentiation patterns affected by the morphological structure and soil composition of different types of microtopography, and natural sealing and artificial promoting restoration measures should be taken accordingly based on the soil environmental characteristics of different types of microtopography in the vegetation restoration of this area.
