Analysis of Soil Nutrient of Native Grassland in Sanjiangyuan Nature Reserve Using Grey System Theory
摘要
Abstract
For studying soil nutrient features of grassland in Sanjiangyuan Nature Reserve,soil nutrient of 9 native grassland soil types were analyzed using grey correlation analysis. The results showed that the quality of bog soil were meadow soil were better than others,and all the grassland soil types were in the categories of grade two. It explained that the quality of grassland soil nutrient in test areas were good. Grey system theory was suitable for evaluating soil nutrient of native grassland.关键词
