[Feasibility to introduce rare tree species Pinus sibirica into China].
Pinus sibirica growing mainly in Siberia of Russia is distributed over the Euro-Asia Taiga forest belt. There are many high-quality populations due to a great deal of variations. This kind of tree has an advantage of standing up to frigid environment, and can spread out in such places that have cold weather and high altitude. In China, boreal forest is a wide-spreaded type of forest that has the largest area and high volume. For this reason, it is feasible to introduce Pinus sibirica into the region that the condition is suitable. Introducing this kind of tree is a strategic project that can improve the structure and quality of our boreal forest. Introducing it can not only meet the demands of improved variety in short time, but also do the experiment of producing edible seeds and build up the developing center of nut, which can be a way of getting rid of poverty of forest region in heavy frigid area where is regarded as infertile area for farming formerly.
