Plant Selection Method in Low Temperature and Low Carbon Landscape Design

In order to satisfy the need of cold weather and low temperature，method of selecting plants in low temperature and low carbon landscape design was studied.Existing problems of selection of dominant plants in landscape design because of low temperature resistance and poor erosion effect were analyzed.According to existing problems，concrete methods of plant selection in low carbon landscape design were put forward.Specific test results showed that，plants could be rationally molded according to oxygen secretion from roots of wetland plants and removal of N and P nutrients in Dianchi，so as to provide reference for design of extremely low temperature and low carbon gardens.
