摘要
目的探讨核电站运行前后周围人口变化趋势，为居民健康状况的监测、评价与医学应急准备提供科学的基础数据。方法以大亚湾核电站1号核岛为圆心，通过描述流行病学调查，分析核电站不同距离（0—5，0～10、0—20和0—30km）、不同运行期间（1990--1992、1993--1997、2002--2005、2006--2010）周围人121的密度、男女比例及年龄性别构成比。结果20年来，4个调查区人口密度均有不同程度增长，其中，户籍人口以0—30km增长最快，年增长率为3．87％；常住人口以0—5km增长最快，年增长率为10．35％。男女比例2010年0—10km上升至101．40，较1990年增加了16．16；1993--2010年，年龄构成在0—10和0—20km范围内，0—14岁比重分别下降了7．78％和9．74％，15～64岁比重分别上升了9．20％和9．75％。结论人口密度低于相关的控制标准，非户籍人口增加幅度较大；性别比例由男少女多转变为男多女少；年龄构成15～64岁比重逐年上升，以劳动适龄人口为主。
[ Objective ] To explore the trends of population change around nuclear power station before and after operation, provide scientific basic data for surveillance and evaluation of the residents health, as well as medical emergency preparation. [ Methods ] The population density, ratio of male-to-female, and age/gender constituent ratio in different survey areas, which were divided ac- cording to different distances to the nuclear island I of Dayawan Nuclear Power Plant （0-5 km, 0-10 km, 0-20 km and 0-30 km） , and different operation periods （ 1990-1992, 1993-1997, 2002-2005 and 2006-2010） were analyzed through descriptive epidemio- logical survey. [ Results ] The population densities of four survey areas have increased in different degrees during twenty years. The growth of census register population in 0-30 km area was the fastest with the annum growth rate of 3.87%, and the growth of perma- nent resident population in 0-5 km area was the fastest with the annual growth rate of 10.35%. The ratio of male-to-female in 0-10 km area reached 101.40 in 2010, which increased by 16.16 as compared with that in 1990. From 1993 to 2010, the age constitu- ent ratio of 0-14 year-old age group in 0-10 km area and 0-20 km area decreased by 7.78% and 9.74% respectively, while that of 15-64 year-old age group increased by 9.20% and 9.75% respectively. [ Conclusion] The population density is lower than the re- lated control standards, and the density of permanent resident populations increase obviously. The sex ratio of population changes from the mode that there are more males than females into the mode that there are more females than males. The age constituent ratio of 15-64 year-old age group has been rising gradually year by year, which is dominated by labor force population.
