طرح ملی مطالعه اکوسیستم های جنگلی غرب ایران (زاگرس)- کرمانشاه

In this survey the dominant slops of Kermanshah province forests was studied to recognize the forest feature and corrolatio0n between all ecological factors which is affected upon forest baring . also all charactristic to trees , shurbs, grass with edafic factors and uisual specifics in 126 plots with 500 m (macroplot ) and 630 plot 1.5 x 1 m (microplot) was studied. Sampling in parallel lines with 100 m distance carried out . Pedology investigation include surface soil and profils ( 126 ) also performed. following : Data analyes with a special soft ware as minitab and spss in variance analyes , regression corrolation , variable corrolation 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 , Islamabade gharb , Darbadam and geomarg with subdamp and cold climate Tazehabad with very cold damp climate , Qalajeh with very cold area , Javanrood with two climate namely intermediate and cold damp and finally Chaharzabar , Haresam , Sarv-e no , Sarpol-e zahab and Qaymas with subcold dry climate. In order to finding the differences between treatments in some variables , variance analysis trial by univariate and multivariate was used . In this precedure by variance analysis between all observation you can find differents between treatments and inter group variance as follow : - Slope percent of area do not affect on the total of plants varieties but the all of regions had a significant and negative influences upon the total of plants .
