摘　　要：作者在进行福建省畲族人口健康素质抽样调查中，对畲族的近亲结婚率、平均近交系数、近亲结婚类型、近亲结婚的有害遗传效应以及异族通婚进行研究。１９９４年４月至５月，在福建省的福安市穆阳乡、漳浦县赤岭乡和上杭县官庄乡，调查畲族婚姻６３３５对，其中近亲结婚５４对。一级表亲占近亲结婚的９２．５８％。近亲结婚率０．８５％，平均近交系数５．７２×１０，异族通婚率４１．８８％。近亲结婚率和平均近交系数与国内报道的３１个民族比较，分别在第２８位和第２６位。异族通婚率与国内报道的１８个民族比较，居首位。１９５０年以后，近亲结婚率有上升趋势，异族通婚率呈下降趋势。近亲结婚所生的０—１４岁子女遗传病患病率显著高于非近亲结婚组。A survey on the consanguineous marriage of ‘She’ ethnic group was carried out in three districts (xiangs) of Fujian Province. The total number of marriages studied was 6335, among them there were 54 consanguineous marriages, with 925% taking place between the first cousins on maternal side. The percentage of consanguineous marriage and average inbreeding coefficient were 085% and 572×10-4 respectively. The percentage of mixed marriage was 4181%. The rate of hereditary diseases among the children (0—14 years) of consanguineous marriages was significantly higher than that of marriages between nonrelatives. 
