A Discussion about the Structure Law of Picea Crassifalia Kom on Northern Slop of Qilian Mountain |
| |
| Abstract: | We have made such investigations and studies as the dist- ributing proportion of various land arer in the forest area of Qilian Mountain, the structure law of tree diameterclass distrib- ution, the agegroup classification by the check of forest resou rces, and the 'fixed sample plot and six trees in round sample plot which have been set up since 1977. Some theoretical basises have been provided for how to pro- tect the present forest, how to develop the management actions actively, how to enlarge the forest coverage continuously and bring the effects of water resource conservation and the ecolo- gical balance maintewance into full play. |
