摘　　要：采用对比分析法和加权平均法,从多个维度对山东省省级测量标志普查数据进行了分析和预测,可为全省采取有效的标志管理和维护措施提供依据。结果表明,测量标志总体可利用性较高,但在类型、等级、区域、埋设年代、占地类型、设施维护等方面存在差异;造成标志不可利用的主要因素是破坏、迷失和失去效能等,预测年平均不可利用数约为54座。We used the comparative analysis method and weighted average method to analysis and predict the survey marks census result data in Shandong Province from multiple dimensions in this paper. The results show that the availability of the marks is obviously higher than the unavailability, but there is much difference in the types, grades, regional distribution, buried time, occupation land use types, and facilities maintenance types of the marks. The main factors making marks unavailable are lost, damage and loss of efficiency. In addition, the estimated number of annual unavailable marks is about 54. This study can provide a basis for the effective mark management and maintenance measure.
