土壤钛值所反映的风化度水平与紫色母岩的风化度趋势一致。
The weathering degree showed by the titanium value of the soil is in accord with that showed by purple parent rocks.
结果显示，紫色沉积岩发育的土壤，在一定程度上继承了母岩的特点，化学风化作用微弱。
The results show that the soils have, in varying degree inherited some properties of purple sedimentary rocks for their very weak chemical weathering.
但紫色土成土母岩结构疏松，易风化，抗蚀性低；
But the structure of purple soil parent material is loose and easy to efflorescent, anti-erodibility;
