| 摘 要： | 选取褐土烟区植烟村为研究对象,在87 hm2的烟田采集耕层( 0～20 cm)土壤样品81个,在GIS支持下研究了该村土壤pH,有机质、全氮、碱解氮、速效磷、速效钾和阳离子交换量的空间变异规律.结果表明,土壤pH和全氮的C0/(C+C0)比值＜25％,表现出高度的空间相关性；土壤有机质、速效磷、速效钾和CEC的C0/(... |

| Abstract: | 81 top-layer(0-20 cm) soil samples from a field(about 87 hm2) of Cinnamon soil in a tobacco-planted village were taken to analyze the spatial variation of soil pH,organic matter(OM),total nitrogen(TN),alkalized nitrogen(AN),available phosphorus(AP),available potassium(AK) and CEC with the support of GIS.The results showed that soil pH and TN had strong spatial correlation with the ratios of C0/(C+ C0)<25%-OM,AP,AK and CEC had moderate spatial correlation with C0/(C+C0)ratios of 30% to 50%-while AN showed no... |
