| Abstract: | The analysis result of living form, ecotype and flora character of gramineous plants in natural grassland of Hebei province indicated that the dominant living form was perennial herbaceous, which amounted 78.4% of total. The ecotype components consisted of 77.2% of mesophyte, 16.0% of xerophyte and 6.8% of hygrophyte, respectively. A flora diversity was found. Forty-two genus, 57.5% of total, were temperate distribution and twenty-four genus, 32.9% of total, were tropical distribution. |
