The uncertainty response of soil fungi community to climate warming in alpine agroecosystems will limit our ability to fully exploit and utilize soil fungi resources, especially in alpine regions. In this study, a warming experiment was conducted in one perennial leguminous agroecosystem [i.e., alfalfa ()], perennial gramineous agroecosystem (i.e., ) and annual gramineous agroecosystem [i.e., highland barley ( L)] in Tibet since 2016 to investigate the response of soil fungi community to climate warming. Soils at two layers (i.e., 0-10 cm and 10-20 cm) were collected in August 2017 to estimate soil fungi community based on the ITS method. The α-diversity, community composition and functional group abundance of soil fungi in the leguminous agroecosystem were more sensitive to climate warming. The α-diversity of soil fungi in the perennial gramineous agroecosystem were more sensitive to climate warming, but topology parameters of soil fungi species cooccurrence network in the annual gramineous agroecosystem were more sensitive to climate warming. Compared with 0-10 cm, soil fungal α-diversity, community composition and functional group abundance at 10-20 cm were more sensitive to climate warming. The topological parameters of soil fungi species cooccurrence network at 0-10 cm in the gramineous agroecosystem were more sensitive to climate warming, but those at 10-20 cm in the leguminous agroecosystem were more sensitive to climate warming. Warming increased the differences of soil fungi α-diversity and functional composition. For the agroecosystem, warming increased the abundance of soil pathogenic fungi but decreased the abundance of soil symbiotic and saprophytic fungi at 10-20 cm. Therefore, responses of the soil fungi community to climate warming varied with agroecosystem types and soil depth. Climate warming can alter the differences of the soil fungi community among agroecosystems. Changes in soil fungi community caused by climate warming may be detrimental to the growth of alpine crops, at least for perennial in Tibet.
高寒农业生态系统中土壤真菌群落对气候变暖的不确定性响应，将限制我们充分开发和利用土壤真菌资源的能力，尤其是在高寒地区。本研究自2016年起，在西藏的一个多年生豆科农业生态系统[即紫花苜蓿（）]、多年生禾本科农业生态系统（即）和一年生禾本科农业生态系统[即青稞（L）]中开展了一项增温实验，以探究土壤真菌群落对气候变暖的响应。2017年8月采集了两层土壤（即0-10厘米和10-20厘米），基于ITS方法估算土壤真菌群落。豆科农业生态系统中土壤真菌的α多样性、群落组成和功能群丰度对气候变暖更为敏感。多年生禾本科农业生态系统中土壤真菌的α多样性对气候变暖更为敏感，但一年生禾本科农业生态系统中土壤真菌物种共现网络的拓扑参数对气候变暖更为敏感。与0-10厘米相比，10-20厘米处土壤真菌的α多样性、群落组成和功能群丰度对气候变暖更为敏感。禾本科农业生态系统中0-10厘米处土壤真菌物种共现网络的拓扑参数对气候变暖更为敏感，但豆科农业生态系统中10-20厘米处的拓扑参数对气候变暖更为敏感。增温增加了土壤真菌α多样性和功能组成的差异。对于农业生态系统，增温增加了10-20厘米处土壤致病真菌的丰度，但降低了土壤共生真菌和腐生真菌的丰度。因此，土壤真菌群落对气候变暖的响应因农业生态系统类型和土壤深度而异。气候变暖会改变农业生态系统间土壤真菌群落的差异。气候变暖引起的土壤真菌群落变化可能对高寒作物的生长不利，至少对西藏的多年生作物而言如此。
