Abstract:

Comprehensive adaptability evaluation can effectively solve the problem of blind selection of landscaping plants in semi-arid areas.Six candidate landscaping plants transplanted in the typical semi-arid area of Yunzhou Districtin Datong City have been selected asresearch objects.The expert consultation method isadopted to select the comprehensive adaptability evaluation indexes of landscaping plants.The weight of evaluation indexes is determined by combining the analytic hierarchy process(AHP)and the objective weighting method of CRITIC.The comprehensive evaluation is carried out by the fuzzy comprehensive evaluation method to calculate the comprehensive adaptability scores of each plant.The results are verified by conducting experiment in the experimental area.The results showed as follows:1)There were three primary evaluation indexes that affected the comprehensive adaptability of plants:ornamental characteristics,growth characteristics and ecological adaptability.There were 15 secondary indexes:flower observation,fruit observation,color leaf observation and shape observation;tree height,ground diameter,crown width increase,reproductive ability;drought resistance,cold resistance,heat resistance,pest resistance,saline-alkali resistance,waterlogging resistance,wind resistance.2)The score of comprehensive adaptability is:Cotoneaster multiflorus>Lonicera caerulea>Euonymus alatus>Lonicera rupicola>Lonicera chrysantha.The score of comprehensive adaptability of Cotoneaster multiflorus is the highest,which is consistent with the experimental result.The results showed that Cotoneaster multiflorus should be selected as a landscaping plant in this area due to its high comprehensive adaptability evaluation in semi-arid areas.

Key words: semi-arid region, landscaping plants selection, analytic hierarchy process, CRITIC, fuzzy comprehensive evaluation
