【Abstract】 The developing speed of urban greening in Shihezi city in Xinjiang Uygur Autonomous Region was very fast in the last few years; and many plant species had been used for greening. The characteristics of plant flora, morphological and ecological properties are studied for using these plant species scientifically. Based on the field survey and literature review, the flora analysis on landscape plant resources in Shehezi was conducted. The results indicated that there are 185 species belonging to 119 genera in 61 families in Shihezi, and most of them were herb plants. Among the 61 families, there were 25 cosmopolitan families, 15 tropic to subtropic families, 13 temperate families, 4 disjuncted families, 3 endemic families and 1 singularity family(Balsaminaceae), respectively. Rosaceae with 26 species was the largest and typical family of landscape plants in Shihezi. 119 genera can be divided into 14 areal types and 7 areal subtypes in Shihezi. At the level of genus,there were 12 widespread genera, 25 tropic-areal genera, 80 temperate-areal genera and 2 genera endemic to China. The temperate-areal genera hold a dominant position, accounting for 67.23% in total genera(excluding cosmopolitan), showing the characteristics of the temperate zone.更多还原
