摘　　要：在现代科学领域,无论自然科学还是人文科学,维的概念被普遍运用。维具有理论体系的实在性,为科学构架所依附。草业科学有自己的维度。草原类型学、草原生态化学、草地农业生态学和草业信息学分别构成草业科学的类型维、化学维、系统维和信息维。其中类型维是认知草原现象的总钥匙。化学维是系统生态效率和经济效率的本初判读刻度。系统维是现代草业和草业科学生命存在和延续的依托。信息维是现代草业科学的神经网络。4维学科独立地阐述了各自完整的理论体系,又互相交叉渗透,贯彻于草业科学各个板块和分支学科之间,既联系又规整了草业科学,形成草业科学整体丰富多彩的多维结构。Concept of dimension has been generally used both in natural science and humanities among modern scientific system.Dimension owns its reality of theoretic system and is one part of scientific framework.Pratacultural science has four dimensions where Grassland Typology,Grassland Ecological Chemistry,Grassland Agro-ecology and Pratacultural Information System constitutes typological dimension,chemical dimension,systematic dimension and information dimension,respectively.Typological dimension plays a key role in cognition of grassland phenomena,chemical dimension is primary indicator of ecological efficiency and economic efficiency of pratacultural system,systematic dimension maintains the existence and continuation of modern pratacultural industry and Pratacultural science and information dimension forms the ‘neural networks’ of modern Pratacultural science.Every dimensional subject has the distinctive and whole theory system whilst four dimensional subjects infiltrate mutually and develop crosswise,which is expressed in three knowledge sectors and the other subjects of Pratacultural science.In this way,dimensional subjects integrate and condense Pratacultural science and hence produce the multi-dimensional structure with high ecosystem diversity.
