Abstract

In this study, the SPATIAL PATTERN, richness, and DIVERSITY of dominant range species in protected areas of Golestan National Park and deteriorated areas of surroundings were evaluated by using PQV, TTLQV (for sedgbrush and grassland) and T-sqaure distance method (for shrublands). The objectives were to determine the SPATIAL PATTERN and DIVERSITY index based on vegetation types. The effects of some environmental factors were traced to find the cause and effect of these patterns. Based on our results the relations between biological types were: TH>CH>GE>HC>CR and from standpoints of life form, the relations were Forbs>Grasses>Woody plants. Grasslands were richer than shrubs. In general, due to lack of rainfall and overgrazing, the unpalatable cushion and annual species were increased, so the richness of rangeland was high in deteriorated areas. In protected areas due to nonuse, lack of competition, DIVERSITY decreased. SPATIAL PATTERN due to the dominant species were not detected but the SPATIAL PATTERN of the same dominant species at local scale were random or clumped. In community the clumped pattern were detected for Artemisia herba Alba. In shrublands the nested pattern of clumped within random or regular were determinated.
