Abstract:

The analytic hierarchy process (AHP) was applied to construct the ornamental value evaluation system for sixteen endemic orchids from Guangdong based on literature review and field investigation. Twelve indexes, including characteristics of flower, foliage and fruit were studied to choose the species that could be applied to horticulture and landscaping. The results showed that the weight of flower diameter reached the highest. The sixteen endemic orchids from Guangdong could be divided into three grades. Grade I (2.8-3.0), including three species, had the highest ornamental value; Grade II (2.5-2.8), including eight species, had medium ornamental value; Grade III (<2.5), including five species, had lower ornamental value. Due to the high ornamental value and excellent biological characters, three species in Grade I, Vanilla shenzhenica, Platanthera zijinensis and Dendrobium jiaolingense, could be introduced and further explored in horticulture and landscape application.
