在多年冻土地区进行供水勘察,要查明含水层特征、分布范围、埋藏条件、地下水类型及地下水资源等问题,首先必须弄清多年冻土的分布及埋藏情况。否则,想查明上述问题是不可能的。因此,在多年冻土区进行供水勘察与一般地区勘察比较就有其特殊性。笔者根据在黑龙江地区的勘察实践谈谈粗浅的认识。 In the permafrost areas for water supply investigation, to identify the aquifer characteristics, distribution, burial conditions, groundwater types and groundwater resources and other issues, we must first understand the permafrost distribution and burial conditions. Otherwise, it is impossible to find the above problem. Therefore, comparison of water supply survey in permafrost regions with that in general areas has its own particularity. The author based on survey practice in Heilongjiang province to talk about the superficial understanding.
