Forest ecosystems in Kermanshah province
In this survey the dominant slops of Kermanshah province forests was studied to recognize the forest feature and correlation between all ecological factors which is affected upon forest bearing. Also all characteristic to trees, shrubs, grass with edaphic factors and usual specifics in 126 plots with 500 m (macro plot) and 630 plots 1.5 x 1 m (micro plot) was studied. Sampling in parallel lines with 100 m distance carried out. Pedology investigation includes surface soil and profiles (126) also performed. Data analyses with a special soft ware as Minitab and spss in variance analyses, regression correlation, and variable correlation was done whether or not statistical comparisons are significant. There was 13 sampling areas with similar climate which some of them have repeated in 6 clima as Bayangan and gahvareh with cold damp climate , Islamabad e garb , Darbadam and geomarg with sub damp and cold climate Tazehabad with very cold damp climate , Ghalajeh with very cold area , Javanrood with two climate namely intermediate and cold damp and finally Chaharzabar , Haresam , Sarv-e no , Sarpol-e zahab and Qhaymas with sub cold dry climate . In order to finding the differences between treatments in some variables, variance analysis trial by univariate and multivariate was used. In this procedure by variance analysis between all observation and recognized number of coppice and seedling trees and shrubs , suckers , DBH, canopy , freshness , kind of herb species , number of species in micro plots and study of annual or perennial species , alt. , p-slop , percent of stone and bare soil .
