Abstract:
In order to quantitative contrast the ornamental characters of perennial flowers and landscape application value , when there are more introduction materials, an evaluation index system for iris perennial flowers was established in terms of natural characters, blossoming characters and growing characters. The importance weights were calculated by the analytic hierarchy process (AHP), and the weight coefficients were modified by the entropy technology, so a synthetic evaluation model about Iris perennial flowers was obtained. According to this model, about 50 species Iris in Shenyang Botany Garden were evaluated and classified. A total of 10 species were selected as the first grade, of which 18 species as the second grade, of which 15 species as the third grade, and 7 species as the forth grade. This study would provide a good theoretical guidance and an important reference value for the application of iris perennial flowers in the landscaping.
