新型灰色关联度分析法在天山北坡天然草地类型质量评价中的应用

An Application of the Grey Relative Analysis to the Evaluation of Grassland Quality of North Part of Tianshan Mountain.

采用不同类型天然草地的优良可食牧草产量、生物产量、化学营养成分、载畜量等定量指标 ,应用新型灰色关联度分析法 ,对天山北坡中段地区的 7个草地类和 33个草地型质量进行定量分析和综合评价 ,结果表明 :利用灰色关联度分析法对天然草地质量类的综合评价效果较好 ,但对复合型不易明确区分 ,可适用于对不同草地型一级进行科学准确的评价 。

The characteristics of thirty three types in seven grassland classes in Tianshan mountain were evaluated by applying the method of grey relative analysis with grassland herbage production, biomass, nutritional components, stocking capacity, ect. The results showed that grey system theory is good at comprehensive evaluation of the grassland types. But it was not easy to distinguish multiplicate types. Based on the results directy stocking capacity plan will be settled.
