摘　　要：为了提高水准网平差精度和促进对定权重要性的认识,本文对目前水准网定权的五类方法进行了比较和实例分析。得到了结论:(1)定权不正确造成水准网各高程点平差结果以及其精度带来影响;(2)不同的定权方法所产生的权不一样,从而平差结果也不一样。本研究结论对水准网平差具有一定的参考价值。In order to improve the adjustment accuracy of leveling network and promote the understanding of the importance of determination weight, five kinds of methods for determining weights of leveling network were compared and analyzed with examples at present. The conclusion were as follows:(1) the incorrect weighting would affect the adjustment result and precision of leveling network;(2) the weights produced by different weighting methods were different, therefore the adjustment results were different. The conclusion of this study had a certain reference value for leveling network adjustment.
