王大纯教授八年前指出:“对地下水来说,储量计算和资源评价二者看来可能并不等同,大概后者包括的范围比前者更力广泛”。我们同意此说法。目前因原“四大储量”概念的不够确切,导致以“资源”取代“储量”,又因对资源概念及其计算原则的不够确切,形成说、算均不清的现状。 Professor Wang Da-chun pointed out eight years ago: “For groundwater, both reserve calculation and resource assessment may not appear to be the same, and presumably the latter will include a wider scope than the former.” We agree with this statement. At present, due to the fact that the concept of the “four reserves” was not sufficiently accurate, the “reserves” have been replaced by “resources”, and the current situation of saying and calculating are still unclear because of the imprecision of the concept of resources and the calculation principle.
