摘要：
The spatial pattern of vegetation in the following 3 semi-natural grasslands in Banska Bystrica, Slovakia, was observed in August, 1998: (1) a grassland sown with improved herbage plants after plowing in 1991, (2) a grassland oversown with improved herbage plants in 199 1, and (3) a natural grassland without any treatment at the time of establishment. A new method of measuring vegetation was adopted: in each grassland, 50 quadrats 50 cm x 50 cm, composed of 4 smaller cells 25 cm x 25 cm, were set up, and all the species in each cell were recorded. The sown grassland displayed the highest species richness and diversity though its spatial heterogeneity was very high while in the natural grassland these characteristics were least pronounced. The highest species richness and diversity could be maintained on the average in the sown grasslands although their plot-to-plot variations were very large.
