摘要
为了客观评价云南省不同地区石漠化土壤的理化性质,为不同石漠化地区植被恢复提供理论依据,采集昆明、宜良、弥勒、建水和文山5个典型的石漠化地区土样,对其进行土壤粒度、理化性质和元素组成分析。结果表明:石漠化地区的土壤主要以砂粒、粉粒为主,保水性差,抗旱力弱;石漠化土壤中有机质、N、P、K、速效P、速效K的含量低,土壤肥力差;石漠化土壤矿化严重,矿质元素含量高,土壤风化程度低,可溶性钙镁和不可溶性钙镁含量高,不适于植物生长。云南省昆明、宜良、弥勒、建水、文山5个典型石漠化地区的土壤理化性质有所差异,但是差异不显著,几个典型石漠化地区可以采取相似的植被恢复模式。
In order to evaluate the soil properties of karst rocky desertification（KRD） objectively in different area of Yunnan Province,so as to provide theoretical basis for revegetation of karst rocky desertification in different area of Yunnan Province.The author analyzed particle size,physical and chemical properties,and elements of 5 soil samples,which were collected from typical rocky desertification area in Kunming,Yiliang, Mile,Jianshui and Wenshan.The results showed that：the sand and power particle were dominated in 5 soil samples from typical rocky desertification area,bad retention water and weak drought resistance.The content of organic matter,N,P,K,available P,available K were low in soil of rocky desertification area,poor soil fertility.Rocky soil mineralization serious,the content of mineral elements,soluble and not soluble calcium magnesium was high in rocky soil samples,low degree of soil weathering,it was difficult to grow for plants on soil of rocky desertification area.There were differences of physical and chemical properties in Kunming, Yiliang,Mile,Jianshui and Wenshan of Yunnan,but the differences were not significant,similar recovery mode could be used in 5 soil samples from typical rocky desertification area of Yunnan.
