| Abstract: | Qiao Mountain forest area, an important seed harvest base, is located in the central distribution region of Pinus tabulaeformis Carr in China. The seed yield of Pinus tabulaeformis Carr for recent years has been very low, to the extent of no harvest. This paper studied the influential factors such as stand distribution, aspect of slope, density of stand and disease and pests within the fine variety base as well as the seedharvest base of Pinus tabulae formis Carr.. Measures for improvement were put forward, accordingly. |
