There are many small street parks in Zhanjiang City, however, plant landscapes in such parks lack in regional characteristics because of blind copy and random planting. By analyzing plant landscapes in typical street parks in Zhanjiang, and borrowing the theoretical research framework of linguistics, this paper concluded the vocabulary, sentence,chapter and grammatical rules of plant landscape design, in order to explore new methods for the plant landscape design of small parks in tropical coastal regions.展开更多
