Abstract

This paper investigated and analyzed the Behaviour of sample indices for detection the spatial distribution pattern of QUERCUS BRANTII, Pistacia atlantica, Acer cineracense and Lonicera nummularifoliain oak mixed forests in northern of Illam province. In this research the area of plots was 2000 m2 that determined by minimal area method. Plots have established by random systematic method. In this study the SPATIAL PATTERN detection indices included Morisita, standardized Morisita, green, lioyd's index of patchiness and variance to mean ratio, which their values calculated for every species in different sample size (20, 26, 35, 46, 55, 65, 75 sample plots) and their behaviour studied in relation to increasing the plot number. Result showed that all of the indices detected the clumped pattern for every one of species in different size of samples. However, levels of clumping varieties with increasing the number of samples. In this research concluded that the best index is the STANDARDIZED MORISITA INDEX which is independent of sample size, species kind and population density. In this case GREEN COEFFICIENT had behaviour better than the other indices except the STANDARDIZED MORISITA INDEX.
