一、解答技巧1.明确概念和计算方法人口类试题主要涉及三个方面的知识要点,即人口的增长与分布、人口的迁移、人口容量与人口问题。要正确解答包含这些知识要点的试题,就要明确一些人口的概念和计算方法。(1)解读常用的计算公式人口增长率=人口自然增长率+人口机械增长率(人口迁移率);人口的自然增长=出生人口-死亡人口;净增人口数=迁入人口数-迁出人口数+人口自然增长数。(2)了解新概念,学会计算方法近几年的高考题和各省市的模拟题出现了
First, the skills to answer 1. A clear concept and calculation methods Population test questions mainly related to three aspects of knowledge points, namely population growth and distribution, population migration, population capacity and population issues. To correctly answer the questions that contain the key points of these knowledge, it is necessary to clarify some concepts and calculation methods of population. (1) Interpretation of Commonly Used Calculations Population Growth Rate = Natural Population Growth Rate + Mechanical Growth Rate of Population (Migration Rate); Natural Population Growth = Birth Population - Death Population; Net Population Increase = Number of Immigrants - Moving Out Population + natural population growth. (2) to understand the new concept, learn to calculate method In recent years, college entrance examination questions and provinces and cities simulation questions appeared
