Analysis of altitudinal distribution patterns of families of seed plants in Baishuijiang National Nature Reserve in Gansu Province
Distribution pattern of tree species richness along an altitudinal gradient in Kanas of Xinjiang
The diurnal range of temperature indicated a U-shaped pattern along the altitudinal gradient, with a lowest value at the middle elevations (about 1600 m).
The fitted curve of both diversity and richness of herb layer with DCCA axis 1 was more significant than that fitted with altitudinal gradient, while that of shrub layer showed the opposite trend.
The holistic distribution characteristics of 4 species groups: evergreen vs. deciduous and tree vs. shrub species along the altitudinal gradient were then analyzed.
