Abstract

In this study, BEECH PHENOLOGY in three altitudinal range (400 to 700 m, 700 to 1000 m and 1000 m to 1300), in both aspect (North and South) and in the mountainous forested areas located in Guilan province, 21 were studied. A total of six-hectare plots in each plot selected 100 healthy trees marked in different months and years were visited several times and observations were inserted in the relevant tables. Also LISSIII-IRS satellite images during the study period were used. After geometric correction accuracy of less than 0.5 pixels and atmospheric correction of images produced in NDVI Iranian BEECH phenological stages were monitored. Results indicate the emergence of leaves and flowering of the third week of April to first week of May, beginning of leaf loss in early October and the end of the fourth week of leaf loss in December is the first weekend. All interpretations of the phonological days after the passing of years into the analysis results showed that were reviewed included in all levels, altitude, direction and types of phonological characteristics of studied were significantly different from each other. Correlation matrix was calculated based on the traits that a significant negative correlation between rainfall and average temperatures of LEAF EMERGENCE, flowering and the rate of emergence was scored. Correlation between average temperatures complete with leaves, falling leaves, the rate and amount of flowering fruit week was also significant and negative. Maximum NDVI 0.6 complete leaf stage and increase the value of NDVI 0.31 LEAF EMERGENCE stage and reduce the NDVI value of 0.33 phase AUTUMN BEECH leaves in Iran shows.
