读“我国西部各省区土地及草地退化状况比较图”（图11）
图11
小题1:据上图， 判断下列叙述正确的是
A．甘肃省沙漠化占土地总面积比例最大
B．内蒙古水土流失的面积与宁夏一样多
C．西北各省区沙漠化的自然原因主要是干旱
D．云南、贵州两省水土流失严重的人为原因主要是过度放牧
答案：C
题目分析：新疆沙漠化占土地总面积比例最大，A错误；内蒙古和宁夏水土流失所占比重大致相同，但由于内蒙古的土地总面积远大于宁夏，故B错误；西北地区位于温带大陆性气候区，气候干旱，形成大面积荒漠，C正确；云南、贵州水土流失严重的人为原因是滥砍滥伐，过度破坏植被。
点评：本题难度一般，学生需要以我国的区域地理概况为背景，并能结合图示获取选项信息，注意“比重”与“面积”的差异。
