摘要: 本文通过系统梳理定性的植被-生境分类法(Vegetation habitat classification system,VHCS)和定量的草地综合顺序分类法(Comprehensive and sequential classification system of grassland,CSCS)在青海省草地资源调查过程中的发展史,阐述了二者在不同历史时期的表现形式。通过对分类系统指标的对比发现,VHCS和CSCS在应用于草地分类时既有相通之处,又有所差异。结果表明:通过对比VHCS与CSCS的温度、湿润度及划分出的草地类型优势植物种类和分布区域发现,VHCS在热量级的划分上精确度较小,VHCS和CSCS湿润度划分指标的标准和范围基本一致,但对应的景观类型存在明显差异;二者的优势植物对应基本一致;CSCS的分布区域侧重以行政区域为单位,而VHCS则将分布区域按照地形来划分。文章基于以上结果,分析了目前青海省草地分类时面临的问题,并提出针对性的解决措施,为指导青海省草地分类和管理提供基础理论依据。

Abstract: This paper systematically compared the qualitative Vegetation Habitat Classification System (VHCS) and the quantitative Comprehensive and Sequential Classification System of grassland (CSCS) in the process of grassland resource survey in Qinghai Province,and the forms of their performance in different historical periods were described. Through the comparison of the classification system indicators,it found that VHCS and CSCS had both similarities and differences when applied to grassland classification. The results showed that:By comparing the temperature,humidity and the dominant plant species and distribution areas of grassland types of VHCS and CSCS,it found that VHCS was less accurate in the division of heat level,and the index,criteria and scope of wetness division of VHCS and CSCS were basically the same,but there were obvious differences in the corresponding landscape types; The dominant plant was basically the same in these two systems; The distribution areas of CSCS focused on administrative areas,while the distribution area of VHCS was based on topography. Based on the above results,we analyzed the problems of the classification of grasslands in Qinghai Province,and proposed targeted solutions to provide basic theoretical basis for guiding the classification and management of grasslands in Qinghai Province.
