Application of Fuzzy Analogy Preferred Ratio Based on Euclid Distance in Quantitative Decision of Turfgrass Introduction

Based on the similarity theory of species introduction, a Fuzzy Analogy Preferred Ratio based on Euclid distance was applied to the comparison of the similarity of the ecological habitats of turf grass introduction land and the introduced land. The results of comparison can better reflect the similarity between the introduction land and the introduced ground in quantity, thus making the fuzzy gradual turfgrass introduction problem realize the quantitative decision.
