At present,there is not a complete knowledge system about the characteristics of ornamental plants in Zhengzhou, which is not related to the relationship between plant ornamental characters and temperature and other related factors.To provide a scientific basis for Zhengzhou city to plant seasonal color design,the main color characteristics and the change of the phenology of the Commonly-used Landscape Plants in Zhengzhou city were collected.Through the acquisition of temperature changes in Zhengzhou city in 2015,using Houwen method defines the seasonal time division.The phenology and NCS color characteristics of ornamental characters of 216 kinds of Commonly-used Landscape Plants in Zhengzhou city were recorded in each 7d, and the correlation between them and temperature was summarized.Research results show that:First,2015 in spring in Zhengzhou City period is from March 11 to April 25,the summer is on April 26 to September 10,autumn is September 11 to November 5.Second,tree spring leaf color in 38 standard colors,45 standard color in the shrub, herb distribution in the 26 standard color.
