息管理系统,加强水资源的管理;3.加强宣传教育,提高公众的环保意识和舆论监督。专题二:自然资源的利用与保护知识点梳理:一、水资源1.淡水资源短缺:自然原因:可利用的淡水资源总量有限:河流,湖泊,浅层地下水淡水资源的时间、空间分布不均,平均径流量排名:巴西、俄罗斯、加拿大、美国、印尼、中国人为原因:淡水资源的污染、浪费严重人口增长,经济发展,生产、生活用水需求量增长快 思考:新加坡是热带雨林气候,但新加坡是缺水国家,试分析其原因陆地面积小,地表径流少 经济发达,生产、生活用水量大2.淡水资源短缺带来的危害:制约经济发展影响粮食生产安全损害生态环境损害人体健康引发国际冲突3.我国淡水资源的时空分布规律:时间:夏秋多,冬春少,年际变化大空间:南多北少,东多西少文档编码:CW2X7L8N9M5 HF3N10Z9A6R8
