我们采用随机抽样的方法,于1988年2月—4月对宜春市城乡2181对夫妇的近婚状况进行了现况调查.城乡的总近婚率是3.62%,其中农村为4.38%高于市区(0.85).迟婚类型以表兄妹为多占69.6%.调查结果表明,结婚年代、男方结婚年龄与近婚有关,而男女双方结婚次数,女方结婚年龄对近婚影响不大.同时近婚对子代20岁前早率亡及子代遗传病的发生率有明显影响. We conducted a random sample survey of recent marriages of 2181 couples in urban and rural Yichun from February to April 1988. The total near-marriage rate for urban and rural areas was 3.62%, of which rural areas were 4.38% higher than the city (0.85) .The type of late marriage is 69.6% of the cousins.The survey results show that the marriage age of the man is related to the recent marriage, while the number of marriages and the marriage age of the woman have little effect on the near marriage. Marriage to the offspring before the age of 20 and the offspring of genetic diseases have a significant impact on the incidence.
