The study results show that:①The distribution of Cd in shallow surface soils is characterized as: The content of Cd in lacustrine deposit, alluvial lacustrine and alluvial-diluvial low-lying plain is 1.4 to 1.8 times as high as in alluvial-diluvial high valley flat and alluvial-diluvial high bank physiognomy areas.②The content variation of Cd in horizontal distribution was controlled by clay primarily and OrgC secondly. The variation of OrgC was major factor that affected the content variation of Cd in vertical distribution.

结果表明：①研究区浅层土壤中w的分布特征为，湖积低平原区、冲－湖积低平原区及冲洪积低洼平原区地貌成因类型土壤中的含量明显高于冲洪积高漫滩平原区、冲洪积高亢平原区地貌成因类型土壤，其质量分数差异达1.4~1.8倍；②研究区不同地貌成因类型土壤中，w的横向分布特征主要受黏粒含量分布的控制，其次是wC(下标 org；垂向分布特征的主要控制因素是wC

The indices comprise the greatest rock's volume in alluvial cone, the greatest cognizable single alluvium's thickness, the surface slope in alluvial cone, the vegetation and land use, the soil erosion, and the runoff.

在荒溪分类的基础上，提出了荒溪内危险区划分技术，给出了不同荒溪类型沟道危险区划分方法和冲积圆锥危险区划分的指标体系（冲出石块的最大体积、可辨认的单次淤积的最大厚度、冲积圆锥表面坡度、植被状况和土地利用情况、侵蚀状况、径流状况等）及数量化评分方法。

Test and analysis show that, the distribution patterns of the tangent veloctiy fields in the big cone area and the small cone area, which are comprised of para-free vortex and para-forced vortex, are basically identical without a change of the radius of the boundary surface; with the increase of the angle of the small cone, the para-free vortex area decreases and the para-forced vortex area increases, and the emulsifiability of the fluid drips increases with the increase of velocity gradient; the tangent velocity increases with the increase of inlet flow, and the maximum tangent velocities of both the big cone area and the small cone area are 4.94 times of the inlet flow; and the maximum tangent velocity increases with the increase of the split ratio and with the radius of the boundary surface not changed.

试验分析表明，大锥段和小锥段切向速度分布规律基本相同，均由准自由涡和准强制涡构成，分界面半径rm没有变化；随着小锥角θ的增加，准自由涡区缩小，准强制涡区扩大，速度梯度增加会加大液滴的乳化程度；随入口流量增加，切向速度增大，经拟合得出大锥段和小锥段的最大切向速度均为入口流量的4.94倍；分流比加大，分界面半径基本不变，最大切向速度增加。
