A central solar heating plants with seasonal storage （CSHPSS） can provide more than 50% of thermal energy for domestic hot water and winter heating of regional buildings. The CSHPSS has been used in Europe and America. The thesis introduces the system with seasonal storage, four basic devices, and the evaluation indexes. Based on the analysis of related advances at home in recent years, the problems to be solved are pointed out.%跨季节蓄热太阳能系统可为区域建筑提供生活热水用热和冬季采暖用热，供热量可占用户热量总需求的一半以上，欧美等国已经建成多个实际工程。介绍了跨季节蓄热太阳能集中供热系统及四种蓄热装置，给出了太阳能供热系统的评价指标，总结了国内该领域的研究现状，提出进一步有待研究的问题。
