摘　　要：探讨盐碱土壤对堤坝蚁害的防治作用,消除堤坝蚁害隐患,确保水利工程安全运行.在新建堤坝时,采用盐碱土壤作为筑堤的土体,老堤加高加固时,采用盐碱土壤铺盖在堤坡上和采用海水(或盐水,含盐度1%以上)浇灌堤身的方法来防治堤坝蚁害.根据2001年对钱塘江海堤蚁害普查的结果,呈盐碱土壤的海堤没有蚁害,并结合临江围堤和老海堤加高加固的建筑年代,得到盐碱土壤防治堤坝蚁害的有效期达20年以上.不污染环境,比较经济,施工简便,可防止堤坝遭受土栖白蚁的侵入.The paper discussed the application of ant damage to dikes with salinealkali soil to remove the hidden damage of ants to dikes and keep the hydraulic works in safety operation situation. In new dikes, salinealkali soil could be applied to refill the dikes. In the rehabilitation of old dikes, salinealkali soil or sea water could be used to cover or water the old dikes to prevent the dikes from damage of ant. According to the investigation of Qiantangjiang River dikes, the method has been effective for 20 years. The method is pollution free, economic, easy to apply and effective to prevent dikes from damage by ants. 
