| 摘 要： | 以东北黑土区典型坡耕地——海伦市光荣小流域为研究区域，通过田间采集土样，并结合GIS空间分析、常规统计学和地统计学方法，研究了区域坡耕地地形因子对土壤水分和容重的影响。结果表明，坡度对两者的影响最大；高程和坡位的相关性也达显著水平；坡向影响则不显著。坡度表现为与两者均呈显著负相关，高程和坡位则对土壤水分的影响达显著水平，坡向对两者的影响均不显著。地统计学分析结果认为，土壤水分、容重分别为中等程度自相关和强自相关。坡度对土壤水分和容重的影响大于其它地形因子，同时对研究区域的水土流失具有较大的影响。

| Abstract: | A typical slope land with black soil in Guangrong small watershed of Northeast China was taken as the study area.Soil water content and bulk density were measured from soil samples.Spatial analysis,classic statistics,and geostatisitcs were used to explore the effects of topographic factors on soil water and bulk density.Results show that slope has the first significant influence on soil water and bulk density and the correlations are significantly negative.Elevation and slope position have significant effec... |
