Abstract: Based on a survey of the urban green land in Neijiang, it is found there are 144 greenery plants in Neijiang, belonging to 144 families, 189 species and 299 categories (including some variants and breeds), on basis of which an analysis is made of the urban green system and the structure of the species of trees in Neijiang. It is suggested that local plants be used to increase city character; and a balance be struck in between points, lines and planes and a reasonable arrangement of arbor species, shrubs and herbaceous plants to enrich seasonal character. 〖WT5HZ〗
