Investigation of Possible Application of Geostatistical analysis for Some factors in forest (Case study: safarood Ramsan)

In order to investigate on geostatical approach for Some factors estimation in the Caspian region, This study was carried out in the forest Safarood Ramsar. Sampling Procedure was performed, based on 150 m by 200m Systematic rectan gular grid. Since geostatical techniques basically , rely on good estimates of spatial auto-correlation, Particularly at short distances , 4 Sample plots were taken 50m away, from central Sample plots in the W-E and N - S directiond. Each Sample plot contained 2 Concentric circles with Area of 300 m2 and 700 m2 . Overall, 92 sample plots were inventoried in 100 hectares. Then experimental variograms for Variables of volume & basal area and number of trees in hectar were calculated and Ploted Using the geo- refrenced inventory plots. The variograms showed Nugget effect for plots 700m2 for volume 30% , basal area 6.82% and number of trees in heetares was 60% and too variograms showed that spatial outo
correlation between basal Area and Volume in plot 300m2 and 700m2 are Very well of factors number of trees in hectars for plots 300m2 and700m2. The results indicated that spatial relationship Between Volume and basal area in hectars is influence space.
