| Abstract: | Site quality of larch (Larix gmelinii Rupr.) in Da Xingan Mountain in Inner Mongolia was studied systematically with about 1000 temporary plots and computer software.
The nature of site class and site index curve was discussed in view of general mathematical model of height growth. The height
growth of dominant tree of four divisions of forest stands were studied and site index tables were constructed respectively.
In order to unify the comparing standard and convenience for management in this region, site index table was constucted too.
Based on discussing the action and accuracy of forest type, a series of site quality evaluation (forest type-site index class-site
index) was suggested.
This subject of study is supported by the National Natural Scientific Fund (No. 39270549). |
