Abstract:: In order to study the structure of the Quercus forest, using the tally data of the typically Quercus forest in Beijing mountainous area as its data resource, the tree height, DBH and canopy diameter of the typical Quercus forest in Beijing mountainous areas were firstly analyzed through R. And then with the images drawn by R overlay those images with the help of Photoshop and ENVI, the forest structure was analyzed base on those data. The FSI of plot 2 is 70.075 2 which is the most maximal, indicating that the structure of plot 2 is the most complicated;while the plot 3 is 42.101 6 which is the most minimal that indicates that plot 3 is the most singleness.
