基于老龄人口累积死亡比例法的省级尺度长寿水平评估

Evaluation of Longevity Level at Provincial Level Based on Method of Cumulative Death Percentage of Aging People

当前对长寿地区的研究侧重于环境成因探索,而对长寿地区的辨别研究较少。通用的表征长寿地区的相关指标中,长寿人口比例指标在不同时期发生较大波动,人均预期寿命指标反映年轻人和低龄老年人的存活率。本文提出了用老龄人口累积死亡百分比评估长寿水平,以第五次、第六次全国人口普查数据为例,计算了省级单元长寿水平。与长寿人口比例方法比较,该方法结果相近,但更稳定,波动更小。研究表明,海南省是中国长寿水平最高的地区,海南地区的自然环境与长寿的关系值得深入研究。

At present,the study of longevity area focuses on the exploration of environmental causes,while the discrimination study of longevity areas is weak.The general indexes to represent longevity meet some problems,longevity ratio is influenced by the population inertia and fluctuates a lot in different periods,life expectancy index mainly reflects the survival rate of young people and young elderly.This paper presented cumulative death percentage of aging people,the fifth and the sixth national census data were taken as an example to calculate the provincial longevity level.This method is more stable than the longevity ratio method.Research showed that Hainan Province is the most significant longevity areas,the relationship between natural environment and longevity in Hainan Province is worth further studying.
