Study on the Cracking Process of Purple Shale and the Characteristics of Alluvial Purple Soil Developed From Suining Group

南方丘陵紫色页岩地区土壤可蚀性因子K值的确定&以湖南衡阳为例

The Determination on Soil Erodible Factor-K Value in Purple Rock Hilly Area of Southern China & A Case Study in Hengyang City , Hunan Province

河流冲积物、石灰岩、白云岩和钙质紫色砂页岩等发育的土壤CEC较高，而砂岩发育的土壤CEC较低，其余4种母质（岩）发育的土壤CEC介于它们之间。

CEC in the soils developed from fluvial sediment , limestone , dolomite and calcareous purple sandy shale is higher ; CEC in the soils developed from sandstone is lower ; CEC in the soils developed from the rest 4 types of parent material / rock are between them .

A STUDY ON THE DEVELOPMENT , UTILIZATION AND CONSERVATION OF THE ERODED LOW HILL PURPLE STONE AREA XINGGUO COUNTY ── Change of soil fertility after the re-establishment of the ecosystem

碳酸岩和紫色砂页岩二种岩性的土壤，造林成活率和植被恢复覆盖情况：在苗木种源、造林时间、造林质量相同的情况下，二种岩性的土壤其柳杉工程造林成活率差异显著。

In the soil of carbonatite and purple sand shale , that the same of seedlings provenance , planting time and quality of afforestation makes survival rate of Japanese cedar reforestation project a significant difference in the two soil lithology .
