Abstract: To establish evaluation system for Crassulaceae succulents cultivars and select suitable succulents cultivars for introduction and cultivation in Suqian, an evaluation system for the succulent plants in Crassulaceae was established from four aspects:ornamental quality,ecological quality,difficulty of reproduction and maintenance,and market potential.The evaluation system was constructed based on plant shape, leaf shape, leaf color, color stage, heat resistance, cold resistance, disease and insect resistance,viability, reproduction difficulty, maintenance difficulty, frequency, sales volume, price and price fluctuation. Using the method of analytic hierarchy process (AHP ), 32 species of Crassulaceae succulent plants were evaluated and analyzed.The result showed that among 14 evaluation indexes,the sales volume,heat resistance,price fluctuation,viability and color stage weight ranked the top five,which had a great impact on the comprehensive quality of Crassulaceae succulent plant varieties.According to the composite index,32 varieties were divided into three grades. Eight species were classified as grade Ⅰ,and suitable for introduction and application in Suqian.Twenty-one species in grade Ⅱ should be selected for introduction and application according to actual needs,and three species in grade Ⅲ were not suitable for introduction and cultivation in Suqian.AHP can effectively evaluate and classify the Crassulaceae succulents cultivars,and the evaluation results are basically consistent with the actual performance of cultivation and application.
