采集海拔２２００～３８００ｍ川滇高山栎（ＱｕｅｒｃｕｓａｑｕｉｆｏｌｉｏｉｄｅｓＲｅｈｄ．ｅｔＷｉｌｓ．）８个群体的样品，应用同工酶电泳的方法研究其遗传变异水平，并发现遗传变异水平随着海拔高度变化呈以下趋势：海拔２４００～３３００ｍ川滇高山栎的遗传变异水平较高，而海拔３８００ｍ及２２００ｍ群体的遗传变异水平均有降低的趋势。另外，还发现人为干扰、日照多少对遗传变异水平均有影响。
Eight samples from 8 populations of Quercus quinifolioides Rehd. Et Wils. Collected at an altitude of 2200 ~ 3800 m were collected and analyzed for isozymes by means of isozyme electrophoresis. The results showed that the genetic variation with the altitude showed the following trend: The genetic variation of ~300 m in Quercus mongolica and Quercus mongolica is higher, while the genetic variation of 3800 m and 2200 m at altitude is decreasing. In addition, it was also found that human disturbance, sunshine and how much have an impact on the level of genetic variation.
