Analyzes of Species Diversity in Ecological Species Group:<br /> Case Study in The Kurdista's Kouhsalan Habitat<br />
Journal Title: محيط شناسي - Year 2008, Vol 34, Issue 46
Abstract
Species diversity is one of complex biological concept. The reason of change in species diversity and control mechanism of this change is one of ecological salient question. Conservation of biodiversity is final goal of natural resources management. In this research, species diversity has been analyzed in important Kurdistan's Kouhsalan habitat. On cluster sampling method 82 plot were obtained. Clustering Analysis method was used to determined ecological species groups. Species diversity was calculated using Shannon-Wiener index, and relationship between Species diversity and soil surface cover investigated by regression analysis. Duncan's test was used for comparison of means. In this habitat, 224 species were recorded. On Clustering analysis, three groups with indicator species such as Quercus brantii, Hordeum bulbosum and Prangos ferulaceae were obtained. Shannon- Wiener index value for three groups and total area calculated 1.98, 1.95, 1.50, and 1.85 respectively. In groups and total area, linear positive model was significant between species diversity with total plant cover and herbaceous plant cover. In first group and third group, linear negative and positive model observed between species diversity with woody plant cover, respectively. Relationship between Species diversity and other factors was not significant. Linear positive model between species diversity with plant cover is an important guide for ecosystem management. Planning and projects should let it be so that conserves the vegetation cover, species diversity and natural ecosystem.
