Distribution of organic matternitrogen and phosphorus along an altitude gradient and productivity change and their relationships with environmental factors in the Alpine meadow;

Changes of the diversity in plant community along altitude gradient in Dongling Mountain,Beijing,China,were studied in 2000 and 2003.

Species richness patterns of Picea schrenkiana var. tianschanica communities along an altitudinal gradient at different longitudes in Xinjiang of Northwest China;

Species abundance distribution of Quercus liaotungensis forest along altitudinal gradient in Dongling Mountain,Beijing;

Distribution patterns of woody plant diversity in stream riparian forests along an altitudinal gradient in Changbai Mountains.;

Soil CO_2 emission distribution along an elevation gradient and the controlling factors in the forest ecosystem;

Size structure and spatial pattern of Quercus liaotungensis population along elevation gradient in Dongling Mountain,Beijing

Six plots with each area 1 600 m~2 which were analyzed by different species diversity measures were installed in the evergreen broadleaf forest through the change of elevation gradient in the north of Fujian.

The paper studys the β-diversity pattern of subalpine meadows in Wutai Mountain with the altitude above sea level by analyzing diversity index in terms of the binary and numerical data,Cody index,Wilson index,Shmida index and Sorenson index,and Bray-Curtis index in term of numerical data.

By observing and analyzing the shooting rhythm of Chimonbambusa hejiangensis that grow at differ-ent altitudes from 400 m to 1200 m, the paper come to the conclusion that at different altitudes there weresignificant or appreciably significant differences not only in the early and late shooting period but also in buddedshoots.
