岩溶区典型根系地下生境的土壤质量分析
- Title:
- Analysis on the Soil Quality of Different Typical Underground Root Habitat Types in Karst Areas
- 分类号:
- S158.2
- 摘要:
- 选择岩溶区三种不同的典型根系地下生境类型土壤为研究对象（类型Ⅵ——白云岩水平产状多层空间类型、类型Ⅸ——白云岩倾斜产状多层空间类型及类型Ⅺ——白云岩直立产状多层空间类型），根据不同类型的土壤物理、化学及生物学指标，计算土壤肥力的综合指标值，对其土壤质量进行综合分析评价。结果表明：（1）不同植物根系地下生境类型和不同空间土壤层次的土壤指标值差异极显著；（2）不同类型的土壤质量存在差异，且具有明显的层次性，土壤质量表现为白云岩倾斜产状多层空间类型最好，且三种类型的土壤质量均呈现出随土壤深度的增加而逐渐降低的趋势。该文揭示了根系地下生境的土壤质量差异，这为岩溶石漠化区的植被恢复技术研究和治理均有积极的作用。
- Abstract:
- This paper took three different soil of the typical root underground habitat types in Karst area as the research objects (Type Ⅵ-dolomite level occurrence multilayer space types, Type Ⅸ-dolomite tilt occurrence multilayer space types and Type Ⅺ-dolomite vertical occurrence multilayer space types). The integrated soil fertility index was calculated and the soil quality was evaluated according to the different types of soil physical, chemical and biological indicators. The results showed that: (1) soil index of different plant root underground habitat types and different spatial soil levels were extremely significant difference; (2) soil quality of different types existed differences, and had a clear hierarchy, soil quality with white dolomite tilt occurrence multilayer space type was the best, and soil quality of three types decreased with the increase of the soil depth. This article reveals the differences of the soil quality of root underground habitat type, which will play a positive role in vegetation restoration technology research and management in the Karst rocky desertification area.
