Quantitative classification of subalpine grassland under degenerate succession in northwest Sichuan

摘要

The northwestern Sichuan is located at eastern margin of Qinghai‐Tibet Plateau, in which the vegetation is typical subalpine meadow.Two‐way Indicator Species Analysis ( TWINSPAN), which was adopted to conduct the multi‐analysis of the florae, was used to study the distribution patterns of subalpine grassland communities under degenerate succession in the region.
