题目内容
【题目】读江苏和宁夏两省区水资源利用情况对照表，联系所学知识，回答下列小题。
省（自治区） | 人口总数（万） | 人均 用水量 （m3/人 年） | 人均生活 用水量 （m3/人 年） | 人均生产 用水量 （m3/人 年） | 农田灌溉亩 均用水量 （m3/亩 年） | 万元GDP 用水量 （m3/万元） |
江苏 | 9566 | 610 | 70 | 540 | 446 | 570 |
宁夏 | 630 | 1780 | 20 | 1750 | 1352 | 4000 |
【1】表中数据表明
A．宁夏用水总量超过江苏
B．江苏生活用水占总用水量的比重约为宁夏的10倍多
C．宁夏万元GDP用水量是江苏的8倍
D．两省区生活用水比重均大于生产用水比重
【2】宁夏人均用水超过江苏的主要原因是
A．宁夏临黄河，水源充足
B．宁夏气候干旱，蒸发旺盛，工农业发达，生产用水量大
C．宁夏人口密度小，人均水资源占有量大
D．两省区产业结构不同
【答案】
【1】B
【2】D
【解析】
试题分析：
【1】用水总量=总人数*人均用水量，江苏总人数多，用水总量大；生活用水总总用量的比重=人均生活用水量／人均用水量，算出江苏生活用水占总用水量的比重约为宁夏的10倍多，B正确；宁夏万元GDP用水量不到江苏的8倍；生产用水比重=人均生产用水量／人均用水量，两省区生活用水比重均小于生产用水比重。
【2】宁夏人均用水超过江苏的主要原因是两省区产业结构不同，D正确。
