| Abstract: | In order to explore the influence of forest gap on gap border trees(GBT) growth of Larix principis-rupprechtii Mayr,the forest sample plots and gaps were surveyed.The results showed that the diameter at breast height(DBH) of GBT was 1.19 times than that of sample trees,the highest was 1.5 times.The average growth percentage of DBH of GBT was 0.15 percent higher than that of sample trees,and average volume of GBT was 0.004 3 m3 higher than that of sample trees.The growth space index of GBT was higher than that of sample trees,forest canopy gap could promote the growth of the GBT in some degrees. |
