Abstract:

Based on the anterior plentiful investigation and literatures, the geographical compositions and the characteristics of the landscape plants in Xinyang city were studied. The results were as following: (1) the landscape plants were abundant in Xinyang city. In this region there were 545 species, 251 genera and 98 families in landscape plants, which include 54 species, 18 genera and 7 families in gymnosperm and 491 species, 233 genera and 91 families in angiosperm. There were 446 species, 209 genera and 83 families in dicotyledon and 45 species, 24 genera and 8 families in monocotyledon among the angiosperm. (2) the most of the landscape plants belonged to temperate zone types and some belonged to subtropical zone types. The characteristic had a clear transitional. This was consistent with natural geographic location at the north sub-tropical to warm temperate zones of transition. (3) the types of natural flora was only about 1/4, the non-natural floristic composition had an advantage in the landscape plants in Xinyang. We should consider the cultivation of domesticated species to the local natural flora in order to rich landscape and enhance the adaptability of landscape plants.At the same time we should increase the proportion of vines and herbaceous plants in order to form rich and varied landscape.
