摘要
以模糊数学集合理论为基础,试用综合评判法,建立了牧草价值综合评价的因素层次结构、等级标准和数学模型。应用该模型对吉林省西部天然草地28种野生牧草做了实际牧草价值的定量化综合评价。结果表明该方法简便、灵敏,能以定量化形式反映牧草价值大小,有益于不同牧草种质的评定、比较和筛选培育。
On the base of Fuzzy set theory the factor and stage structure and mathematical model of quantitativemultifactorial evaluation for the forage value were put forward.And applied this mathematical model intopractical multifaetorial evaluation for 28 species in the natural rangelands in the western Jilin Province.Theresults showed that this method is very simple,effective and sensitive,it can qualify to evaluate the foragevalue,it is useful for evaluating,comparing,selecting and breeding for different forage germplasms.
