青海草地类型在中国草地分类系统中的归并初探

青海现行的草地类型分类系统,主要依据<青海草地资源>,建立于20世纪80年代.1988年,青海省在全省草地资源调查中,依据1984年厦门会议制定的草地分类系统,编写了<青海草地资源>,将青海全省天然草地划分为9个草地类、9个草地组、173个草地型.由于<青海草地资源>成文早于<中国草地资源>,分类方法和分类单位与<中国草地资源>不同,导致青海草地分类系统与全国草地分类系统差异很大.为了统一规范青海草地分类系统,与全国草地分类系统相一致,现将青海省原用的草地类型归并其中,形成包括10个草地类、8个草地组、167个草地型的青海草地分类系统,通过今后的草地资源调查实践,进一步得到补充和完善,最终形成一个科学的青海草地分类体系.

Preliminary probe to the merging cluster of grassland types in Qinghai by using Chinese Grassland Classification System

The grassland classification system presently used in Qinghai was based on "Qinghai Grassland Resources",and established in the 1980s according to the grassland classification system determined in Xiamen in 1984.In 1988,during the survey of grassland resources,Qinghai Province compiled the book entitled "Qinghai Grassland Resources",according to the book,the natural grassland in Qinghai Province was divided into 9 classes,9 groups and 173 types.Since it was completed earlier than "China Grassland Resources" and the classification systems in two books were different,in turn,the grasslands classification system used in Qinghai was greatly different from the national system.For the purpose of unifying the classification system used in Qinghai with that of the national system,the grassland types in Qinghai was merged into 10 classes,8 class groups and 167 types.This classification practice will be more suitable through field work in the future.
