摘　　要：优秀的天文观察台址,是开展天文学研究的基础。如何根据地理环境特征,在大范围区域快速寻求可能符合的天文观察台址,从而开展进一步的详察和天文条件地表监测,是非常有意义的一项研究。本研究基于地理相似性规律,根据全球一流天文台址的降水、海拔高度、土地利用/覆被类型、人类活动四方面地理环境特征,在青海省海西州范围内选择地理环境特征相似的地点,作为预选优秀天文观测台址。结果表明,海西州大柴旦行委和茫崖市有多处地点其地理环境特征与优秀的天文台址相似,根据需要可进一步地进行地表长期监测。研究成果对基础数据缺乏地区的选址问题研究有较强的指导意义。Excellent astronomical observatory sites are the basis for astronomical research.It is a very meaningful study on how to quickly find possible astronomical observatory sites in a large area according to the characteristics of the geographical environment,so as to carry out further detailed survey and surface monitoring of astronomical conditions.Based on the laws of geographical similarity and according to the four geographical environment characteristics of the world-class observatory site,namely,precipitation,altitude,land use/cover type and human activities,this study selects sites with similar geographical environment within the scope of Haixi Prefecture as the pre-selected excellent astronomical observatory site in Haixi Prefecture.The results show that there are many sites in Dachaidan Administrative Committee and Mangya City of Haixi Prefecture,whose geographical environment characteristics are similar to those of excellent observatories,and long-term surface monitoring can be further carried out as needed.The research results have a strong guiding significance for the study of location selection in areas lacking basic data.
