摘要
采用ArcGIS 9.3和GPS技术对仁寿县龙泉山南端202个土壤样点耕层(0—20cm)的Mn、B含量空间分布特征及影响因素进行了研究。结果表明:龙泉山脉南端土壤中Mn含量由西向东呈先增加后降低趋势,平均含量为(169.70+62.99)mg/kg;B含量由西向东呈逐渐减少趋势,平均含量为(0.51±0.39)mg/kg;在pH各分级之间的Mn、B含量差异性分别达到极显著水平,且Mn含量与pH呈极显著正相关关系;在有机质含量各分级之间的Mn、B含量差异性分别达到极显著水平,且B含量与有机质含量呈极显著正相关关系。
According to the chemical analysis data of Mn and B content which were from the 202 random sampling points in topsoil （0 - 20 cm）, this paper studied the spatial distribution characteristics and influential factors of soil Mn and B in the southern Longquan Mountain of Renshou County based on the software ArcGIS 9.3 and the software of statistical product and service solutions. The results showed that ： The content of Mn showed increasing firstly and then decreased from west to east along the southern Longquan Mountain, with the content was （169.70 ＋ 62.99） mg/kg. The content of B showed decreasing gradually from west to east along the southern Longquan Mountain, with the content was （0.51 ± 0. 39） mg/kg. The differences of the contents of Mn and B were significantly between every grade of pH, and the correlation of the contents of Mn and pH was positive significantly. The differences of the contents of Mn and B were significantly between every grade of organic matter, and the correlation of the contents of B and organic matter was positive significantly.
