摘要
按贵州省陡坡退耕立地分类的原则及分类系统[1~2],在示范区以岩组类型划分类型小区,以坡度等级划分类型组,以土被连续性或土层厚度划分立地类型。共分为2个立地小区、8个立地类型组、20个类型。立地类型和类型组体现了地块空间属性的分异规律,为退耕还林还草、水土保持工程建设提供了基础。
Based on field investigation and study and according to the principles and systems of site classification in Guizhou province, site sub-areas are classified by rock type, site type groups by grade and site type by the continuity and thickness of the soil in the Huajiang Karst Valley Demonstration Area. Thus, the demonstration area is divided into 2 site sub-areas, 8 site type groups and 20 site types. Site types and type groups reflect the spatial attributes of the land, which provides the theoretical guidance for the work of returning farmland to forests and grassland and for the construction of water and soil conservation projects.
