Abstract：Inorder to screen trampling resistant turfgrass varieties at high altitudes in Xining City，13 grasland varieties Poa pratensis L. were used as test materials，and three treatments were set up： no trampling，light trampling and moderate trampling，and 13 indexes such as pingguan quality，growth characteristics and exercise quality were measured，and the gray correlation analysis method was used to comprehensively evaluate trampling resistance.The results showed that the normalized diference vegetation index（NDVI），color and plant height ofsome cultivars increased significantly under light tramplingand decreased significantly under moderate trampling，but‘Selway’and‘Blue Devil’ had no significant changes. The aboveground biomassof most varieties increased under light trampling decreased under moderate trampling，but the belowground biomass all decreased under trampling.‘Blue Devil’‘Feida’and‘Midnight’ maintained high root surface area and volume under moderate trampling.In addition，trampling significantly enhanced soil compaction，surface hardness and ball rebound.The comprehensive multi-index evaluation using the gray correlation analysis method showed that ‘Midnight’‘Feida’and‘Blue Devil’ performed the best and were worth recommending.The results of this study provided a basis for the selection of grass species for urban green space and sports field lawn in high-altitude areas，and might optimize grass species according to trampling intensity to improve economic benefits.
