英文摘要	Terrestrial ecosystems are composed of above- and belowground community, which have been researched separately for many years even though the two subsystems clearly interact with each other. And it is still less understood how the above- and belowground ecosystems co-response to the changing precipitation in this changing world. To understand the interdependence and co-responses of plant-arbuscular mycorrhizal (AM) fungi symbioses to this facet of climate change, we examined the plant and AM fungal diversity and abundance along both, a transect from east to west of the desert which exhibits an annual precipitation gradient and a topographical transect of a typical sand dune which exhibits a gradient of soil moisture but equal precipitation, in a temperate desert in Central Asia. The results showed that community structure and biomass of plants and AM fungi along both transects were positively correlated and related to either precipitation or soil moisture, strongly support the Habitat Hypothesis. We found a soil moisture threshold between 0.64% and 0.86%, below which the variability of plant coverage, plant species richness, spore density and Shannon-wiener diversity index of both plant and AM fungal communities increased sharply yielding in an average threshold of 0.73% for the stability of plant-AMF symbioses. Our results highlight that increasing precipitation contributes to above- and belowground, and particularly to the overall AM-symbiotic stability in a desert ecosystem. This emphasizes the susceptibility and the importance plant-AMF symbioses for ecosystem stability to climate changes across different scales. (C) 2019 Elsevier B.V. All rights reserved.
