云南白水台泉华台地土壤理化性质初步研究
Preliminary Study on Physical and Chemical Properties of Soil in Baishuitai Sinter Platform of Northwestern Yunnan
【摘要】 对云南白水台泉华台地5种植被类型的土壤理化性质进行了研究,结果表明:从以草本为主的裸露地到乔灌木林,土壤含水量、有机质、全氮、水解氮等总体上呈增加趋势,土壤保肥、供肥能力加强,土壤自肥能力也加强;而受成土母质影响的pH、钙镁含量却无大的变化。相关分析表明,土壤含水量、有机质、全氮、水解氮呈正相关关系,而土壤全磷与pH,钙总量和全氮呈负相关关系。
【Abstract】 Physical and chemical properties of soil in 5 different vegetations on Baishuitai Sinter platform were studied.Results indicated that water,organic matter content,total-N and available-N in soil almost increased from pattern of bare earth to forest;the fertility and nutrients of soil enhanced;but pH,Ca and Mg content did not change greatly;correlation analysis showed the correlation of water,organic matter content,total-N and available-N in soil was positive,while total-P and pH,total-Ca and total-N was negative.
