我市位于鲁西南,是一个经济基础比较薄弱的农业市,也是全省地方性氟中毒的重病区。近几年来,由于原材料的大幅度涨价,给本来经费就已十分紧张的防氟改水工作增加了更大的困难。就我市来讲,1986年每个病村改水平均造价为1.545万元,1987年为1.783万元,到1988年增加为2.898万元,比1986年上升了87.64％,而国家财政补助仍为每人病村0.9万元,资金不足十分突出。如何在不依赖国家财政补助的情况下完成防氟改水任务,是当前众人关注,迫切需要解决的问题。几年来,围绕这一个问题,我们根据我市 Our city is located in the southwest of Shandong and is an agricultural city with a relatively weak economic foundation.

Over the past few years, based on this issue, we have based our city
