| 摘 要： | 草业科学是研究草地农业生态系统的科学,主要由三个因子群、三个主要界面和四个生产层构成。其中生物因子群居于核心地位,非生物因子群是生态系统的自然立地条件,社会因子群是草地农业系统所处的社会立地条件。三个因子群是基础课的依据;界面是系统最活跃、最敏感、功能最密集的部分,是科学创新和新的分支学科的生长点;四个生产层是设立二级专业的依据。草业学科的这一框架结构在兰州大学以及相关的院校中试行已经取得初步成果。

| Abstract: | Pratacultural science is a scientific area to study the grassland agro-ecosystem,and mainly consists of three elemental groups,three main interfaces and four production levels.Among three elemental groups,the biotic factors play a key role in grassland agroecosystem,while the abiotic and social factors are the natural and social conditions of the ecosystem,respectively.The three elemental groups set up the foundation for the basic courses;the interfaces are the most active,sensitive and functiondense parts ... |
