统编鲁教版高中必修第二册地理《第一单元 人口与环境 综合与测试》必备知识点集体备课教案教学设计

高中地理新教材合格考必修二知识点总结第一单元人口与环境第一节人口分布一、知识梳理1.人口分布的衡量指标:人口密度:是衡量人口分布的主要指标,它反映一定地区的人口密集程度,是指单位土地面积上居住的人口数。
通常以每平方千米常住的平均居民数量来表示。
计算公式:人口密度=人口数量/面积×100%2.人口分布特点答题模板:(1)人口分布是否均匀(2)分布的方位(疏密,多少);人口主要集中在……3.世界人口分布的特点和规律:特点:目前全世界大约3/4的人口分布在5%的陆地上,具有明显的不均衡特征。
世界人口稠密区:东亚、东南亚、南亚以及西欧和北美东北部等,都是人口稠密区。
至2017年,人口超1亿的国家有中国、印度、美国、印度尼西亚、巴西、巴基斯坦、尼日利亚、孟加拉国、俄罗斯、日本、墨西哥、埃塞俄比亚、菲律宾等。
人口稀疏区:南极洲以及一些荒凉海岛。
规律:北半球中纬度沿海低地平原①主要集中在北半球的中低纬度地带。
②主要集中在距海较近地带。
③主要集中在海拔较低地带。
④主要趋向于城镇地区。
4.热带多雨地区人口分布特点:热带多雨地区,人口最稠密的地方通常不在平原,而在高原和山地。
原因:热带高原和山地的一定海拔范围内,气候凉爽,雨量适中,排水通畅。
此外,这一海拔超出疟蚊分布上限,人们可免受疟疾等疾病袭扰。
5.影响人口分布的因素自然因素(基本因素):气候、地形、水资源和土壤、矿产资源社会经济因素:经济发展水平(最显著)、交通和通信条件、文化教育、政府政策和地方习俗等6.胡焕庸线探究中国的人口分布特点(1)以胡焕庸线(腾冲-黑河一线)为分界线;(2)我国人口的空间分布是东南多,西北少原因:我国东部地区气候适宜,水源丰富,土地平坦肥沃;交通方便,科技水平高,环境可养育的人口多,故人口稠密;而西部地区大多为高原、荒漠,土地可垦殖率低,水资源短缺,生态环境脆弱,生产水平低,环境可养育的人口少,人口分布稀疏。
所以,我国人口分布现状是合理的。
