【摘要】 本文应用数量化理论Ⅰ研究克山病与地理环境之间的关系。首先按网格法把全国分为3825个基本评价单元,并按网格中心法进行评价要素的空间匹配。然后把地理环境特征简化为47个类目,用主因子分析法确定统一的病情指标,最后通过电子计算机,用数量化理论Ⅰ分析克山病空间分布与地理环境之间的关系。从定量角度论证了我国克山病的分布与地带性地理因素之间的关系,进一步揭示了黄土堆积和中生代陆相沉积在克山病分布中的作用。更多还原

【Abstract】 The authors apply the theory of quantification I to study the relationship between Keshan disease and geographical environment. The result not only confirms that the distribution of Keshan disease has a close relation to the geographical zonal factors that was suggested in our early paper, but also reveals the important effect of the continantal deposit of the Mesozoic era and the loess deposit upon the distribution of Keshan disease.更多还原
