| 摘 要： | 通过西藏大骨节病县与非病县棕壤与暗棕壤各土属、土种的分布面积的对比分析对西藏耕型棕壤和暗棕壤分布与西藏大骨节病区分布的关系进行研究.结果表明,西藏大骨节病的分布与棕壤、暗棕壤为主的耕型淋溶土壤的分布有一定的联系,但土壤母质和发育程度不同,对大骨节病的分布影响不同.对于残坡积土壤,病区趋于分布在泥质土壤环境,而麻砂质土壤基本是大骨节病的非病区.同样的母质环境,大骨节病区趋于分布在土壤厚度较小,发育程度较低的地区;就洪积土壤来说,其与大骨节病分布的关系似乎与土壤质地有一定的联系,底部砾石含量高的土壤多集中在大骨节病地区.总体而言,山地棕壤、暗棕壤环境是西藏大骨节病区的主要土壤类型之一,西藏未开发的自然棕壤和暗棕壤环境将是大骨节病潜在危险区,因此系统研究西藏典型大骨节病区的土壤分异对探讨未来西藏大骨节病的分布与流行有重要意义.

| Abstract: | The relationships between KBD distribution and cultivated brown earth and dark brown earth distribution are studied through comparison analysis of areas of different genera and species of brown earth and dark brown earth in those of KBD affected counties and non-KBD affected counties. The results show that cultivated brown earth and dark brown earth are mainly distributed in KBD counties. However, the impacts of the soils on KBD distribution differed from soil parent materials and soil development. For residual soils, KBD affected areas tend to distribute in pelite soil. Acid sandy loam soil is non-KBD affected areas. Even for same parent material, KBD affected areas tend to distribute in those with thinner soil depth and lower development. For diluvial soils, KBD distribution was probably related with soil texture. Soils with high content of gravel in bottom, layer are mostly concentrated on KBD affected area. In general, mountain brown earth and mountain dark brown earth are main soil types in KBD affected area in Tibet. There would be potentially risk areas with KBD in uncultured areas in natural brown earth and dark brown earth. It is very important to systemically probe the soil territorial differentiation in Tibet and its relationship with KBD distribution and prevalence. |
