Diversity between two quadrates within a community decreased with increasing elevation. The peak values of dissimilarity index and Cody index along elevation gradient just matched the ecotones between different vegetation types.

群落內(nèi)的β多樣性隨海拔的升高而下降，而群落間的β多樣性可以很好地反映群落間的相似性關(guān)系玖玖玖在线精品免费视频，β多樣性較大的幾個峰值恰好是不同植被類型間的分界肏屄直接看。

Based on the survey of community plots, a quantitative analysis of the communities at Luya Mountain is performed with TWINSPAN Two Way Indicator Species Analysis and DCA Detrended Correspondence Analysis methods. 82 quadrates collected from Luya Mountains were classified into 28 types by TWINSPAN, which belong to seven vegetation types. The result of DCA indicated that those 28 types were reliable. Diagonal line of the two-dimensional ordination diagram of DCA reflects the gradient changes of elevation, temperature and humidity. It is considered that the major factors that restrict the community distribution of the mountains are elevation、temperature and humidity.

Specifically, the science-majored college students tender to mastery goal orientation. In the test of mastery goal, the junior students get the highest score; the senior undergraduates get the lowest score. There shows a tendency that mastery goal firstly gets strengthen and then gets weaken gradually along with the grade elevation in the college students. In avoid performance goals, the junior students get the lowest score, the senior undergraduates get the highest score. There shows a tendency that avoid performance goals firstly get weaken and then get strengthen gradually along with the grade elevation.
