There is controversy regarding the limiting climatic factor for tree radial growth at the alpine treeline on the northeastern Tibetan Plateau. In this study, we collected 594 increment cores from 331 trees, grouped within four altitude belts spanning the range 3550 to 4020 m.a.s.l. on a single hillside. We have developed four equivalent ring-width(More)
In the National Natural Reserve of the Qilian Mountains, northwest China, automated dendrometers were installed on Qilian juniper (Sabina przewalskii Kom.) in 2010. Here, we present a complete 1-year data series of dendrometer measurements and synchronous meteorological records. The mean daily radius change index curve obtained by first-difference(More)
The use of organic compost combined with inorganic fertilizer can enable balanced fertilization under intensive farming conditions, but little is known about how these fertilization practices affect the composition of microbial in arable soils. In this study, a field trial of a rice–wheat cropping system was established to examine the effects of 8 years of(More)
