Linking Tree and Shrub Biomass to Plant Diversity During Early-Stage Alpine Afforestation.

Afforestation has considerable potential to restore and maintain plant diversity, which is closely associated with ecosystem functions and services. However, there remain numerous uncertainties regarding alpine afforestation performance. Hence, it is necessary to determine the factors contributing to plant diversity during the early stages of afforestation in alpine regions.

[Relationships between phosphorus fractions concentrations in Pinus sylvestris var. mongolica needles and soil available phosphorus].

To make clear whether Mongolian pine (Pinus sylvestris var. mongolica) plantation is limited by soil phosphorus (P) supply in southeast Horqin sand land and to find out the best leaf indicator of soil P supply, the concentrations of total P, inorganic P and organic P in the needles of different age of P. sylvestris var.
