摘　　要：太阳风源自太阳大气,在行星际空间传播过程中被持续加热,然而究竟是何种能量加热了太阳风至今未研究清楚.太阳风普遍处于湍动状态,其湍动能量被认为是加热太阳风的重要能源.然而,太阳风湍流通过何种载体、基于何种微观物理机制加热了太阳风尚不明确,这是相关研究的关键问题.将回顾人类对太阳风加热问题的研究历史,着重介绍近年来我国学者在太阳风离子尺度湍流与加热方面取得的研究进展,展望未来在太阳风加热研究中有待解决的科学问题和可能的研究方向.The solar wind originates from the solar atmosphere.It undergoes heating when it propagates in the interplanetary space.It is unclear what heats the solar wind,a frontier problem in space physics.The solar wind is commonly in the state of turbulence,and the turbulence energy is believed to be an important source of the solar wind heating.However,two key questions remain,i.e.,what is the specific medium heating the solar wind and what is the microscopic mechanism of the heating.This paper reviews the history of the studies on the solar wind heating problem,with the focus on domestic works about solar wind ion-scale turbulence and its heating.This paper also raises several questions to be solved and interesting topics on the solar wind heating in the future.
