摘要
对柴达木盆地盐碱化弃耕地水盐动态进行了监测 ,结果表明 ,该示范区地下水位年变幅为 3.12～ 3.4 6 m,处于临界水位以上。示范区土壤水盐季节动态受当地自然气候条件的影响强烈 ,在 5月和 8月间皆出现有高峰期。
The water-saline dynamic observation of the salination discarded field was conducted in Chaidamu basin. The results showed that the annual change range of water table in the experimental plot was 3.12~3.46 m,which was above the critical depth. The water-saline seasonal dynamics of the experimental plot was affected violently by the region natural climate. Both had peaks in May and August.
