Climatic response of tree-ring width from alpine treeline in the middle of Anyemaqen Mountains, northeastern Tibetan Plateau,China;

Taking the northeast slope of Moxi vally and southwest slope of Kangding vally in Gongga Mountain of Southwest China as sampling sites,this paper investigated the leaf mass per unit area(LMA)and tissue non-structural carbohydrates content(NSC)of Abies fabri distributed at the positions from lower elevations to alpine treeline during the periods of dormancy and vigorous growth.

Mass loss and element release of litter in the subalpine forest over one freeze-thaw season

To understand the effects of Fargesia nitida on forest cycle succession of subalpine forests in Wolong Nature Reserve, Sichuan Province, species diversity and tree regeneration with bamboo(B~+) and without bamboo(B~-) condition of three regeneration stages were investigated.

To understand the effects of seasonal freezing-thawing on the subalpine forest ecosystem processes,the microbial count and biomass in fir(Abies faxoniana) and birch(Betula platyphylla) litters under the condition of freezing-thawing were measured from October 2006 to April 2007 by litter bags method.
