The heat source of the Qinghai-Xizang Plateau not only strengthens the formation and maintenance of the climate background in drylands of China， but also has a significant impact on the climate anomalies there.A deep understanding of the relationship between Qinghai-Xizang Plateau heat source variety and climate anomalies in drylands of China is of great significance for maintaining ecological security， preventing major meteorological disasters and promoting regional sustainable development.This paper reviews and combs the current relevant research on the impact of Qinghai-Xizang Plateau heat sources on climate anomalies in drylands of China， including the climate characteristics of Qinghai-Xizang Plateau heat sources， the impact of Qinghai-Xizang Plateau heat sources on climate anomalies in drylands of China， and the prediction function of Qinghai-Xizang Plateau heat sources’ early signals on climate anomalies in drylands of China.Previous studies have shown that the temporal and spatial distribution characteristics of Qinghai-Xizang Plateau heat sources have significant discrepancy of seasonality， regionality and time stages.By regulating the circulation systems such as the meridional circulation on the northern side of Qinghai-Xizang Plateau， South Asian high， westerly jet and zonal planetary wave， it has an impact on the climate anomalies in drylands of China； At the same time， the Qinghai-Xizang Plateau snow and frozen soil change the surface energy balance and soil water and heat transfer through the land surface process， and affect the Qinghai-Xizang Plateau heat source， which can be used as the early signal for the prediction of summer precipitation in drylands of China.Finally， based on the summarizing of previous research progress and achievements， the future research direction of the impact of Qinghai-Xizang Plateau heat sources on climate anomalies in drylands of China is prospected.Under the background of global warming， there is still great uncertainty in the temporal and spatial variation law of Qinghai-Xizang Plateau heat sources.At present， the way of Qinghai-Xizang Plateau heat source affecting climate anomalies in drylands of China is not comprehensive， and the internal influence mechanism between them still needs to be further studied.
