利用多层递阶模型，在选取影响人口损失大小的动态因子的基础上，建立了可应用于未来人口损失估计的动态预测模型，并由此对中国大陆各区域未来10a的人口损失进行了预测。
Based on the multilevel hierarchical model and the dynamic factors that affect the size of the population loss, the dynamic prediction model that can be applied to estimate the population loss in the future is established, and the population loss of the future 10a in each area of China is predicted .
