Study of distribution pattern and density of vegetative cover in steppe and forest areas of Isfahan University of Technology
Journal Title: International journal of Advanced Biological and Biomedical Research - Year 2013, Vol 1, Issue 7
Abstract
Since density is considered as one of the most important numerical indices to explain quantitative values of a plant community by affecting on many aspects and activity of ecosystem, on the other hand, awareness about plants distribution pattern in environment is an essential preparation for measurement and study of vegetative cover, therefore, in this research determination of density and distribution pattern of vegetative cover were carried out in two forest and steppe areas of Isfahan Industrial University using plots and distance methods. The results explained that, distribution pattern of vegetative cover of forest area had a uniform distribution so that, Point quarter, Ordered distance and T-square methods had a smaller standard error respectively. In the steppe area with bulk distribution pattern, standard error was less in Point quarter, Ordered distance, T-square and plot respectively. On the other hand in forest area, density resulted from Ordered distance, T-square, plot and Point quarter methods were respectively close to the real density. While in the steppe area, density resulted from Point quarter, Ordered distance, Tsquare and plot methods were respectively close to the real density.
