不规则网土壤测量在水系沉积物异常查证中的应用

Application of soil survey with irregular net in anomaly check of stream sediment

在大兴安岭森林沼泽景观区,植被茂盛、土壤表层腐殖质发育,且通视条件差,运用传统的规则网土壤测量方法进行1/5万水系沉积物异常查证,工作周期长、劳动强度大;采用不规则网土壤测量方法进行异常查证,取得了快速评价异常、追踪异常源,缩短找矿周期的效果。

In forest and marsh area of Daxing＇anling Mountains. the vegetation is luxuriant, the humus on soil surface is developed. 1：50 000 hydorographic net sediment with soil survey method with traditional regular net, the working period may be long and intensity of labor is heavy. We used the method of soil survey to go on anomalies check with irregular, achieved the results that quickly evaluate anomaly and trace the source of anomaly and shorten the cycle of looking for mineral deposits.
