[Abstract]:[objective] to study the influence of slope direction on the characteristics of mountain grassland community, and to reveal the variation law of plant community in different periods of growing season. [methods] taking the mountainous grassland on the northern slope of Tianshan Mountain in Xinjiang as an object, the field sampling method was used. The grassland community characteristics of different slope directions (east slope, top slope and west slope, different growing season period from June to September) were measured. [results] 1) the important value of Artemisia frigida showed the west slope of east slope from June to September. The important value of Stipa on the top and west slope was significantly higher than that on the east slope (P 0.05), and the important value of Carex spp showed that the east slope was 鈮，
