Abstract: Through correspondence analysis， statistical data of green-land plants in Jieyang were studied. The results showed that plant landscape diversity will directly affect the plant disposition patterns， then optimizing models of plant disposition in Jieyang area were proposed that plant disposition patterns should be mainly based on native plants， and a variety of plants were used to enrich the landscape configuration， so as to build the regional landscape with local characteristics.
