摘　　要：克山病是一种原因不明的心肌病,传统认为克山病与土壤中微量元素缺乏硒或重金属超标有关。借助东北黑土地调查,笔者在克山县全县开展了土地质量调查,结果表明克山县地区土壤硒含量适量,且克山病高发区存在富硒土壤和富硒农作物,与传统认为克山病区土壤缺硒的认识相悖,此研究为克山病机理研究提供新素材和方向。Keshan disease is an unexplained cardiomyopathy.It is traditionally believed that Keshan disease is related to the selenium lack or the excess of heavy metals in the soil.A land quality survey of black soil in the whole Keshan County shows that the content of soil selenium in this area is moderate.In the high incidence areas of keshan disease,however,there are selenium-rich soils and selenium-rich crops,which is contrary to the traditional understanding of the disease.This study provides new material and directions for further research into the Keshan disease.
