【题目】根据我国某省级行政区2010年基本图表资料,分析回答下列问题。

(1)该省级行政区的人口密度约是 人/平方千米。

(2)该省级行政区是边境 省份(填“沿海”或“边境”),位于我国地势 阶梯。

(3)该省级行政区大部分地区的气候类型是

(4)该省级行政区土地构成中,林地和耕地所占比重较

(5)根据以上信息综合判断,该省级行政区是下图中的 (填数码)。

(6)该省级行政区与④省区都有面积较大的草地分布。目前,我国在草地利用方面存在的主要问题是

【答案】(1) 113

(2)边境 第二级

(3)亚热带季风气候。

(4)大。

(5)②

(6)过度放牧和滥垦草原。

【解析】试题分析:

1)根据图表资料结合人口密度的计算公式:人口密度=总人口/总面积=45960000/394000≈117/平方千米。

2)据图表可以看出:该省区的国境线长为4060千米,而海岸线长度为0千米,说明该省区为边境省份;从其海拔高度为2000米,可知其应该位于我国第二级阶梯(1000-2000米)。

3)据图表可以看出:该省区1月平均气温在0℃以上,夏季多雨,雨热同期,年降水量较多,应该属于亚热带季风气候。

4)据土地利用构成比重图可知:该省级行政区土地利用构成中,林地所占比重最大。

5)根据以上分析可知:该省区为我国边境省份,属于亚热带季风气候,林地比重最大,因此其应是我国的云南省。据图可知:是山东省,是云南省,是广东省,是内蒙古自治区,故本题选

6)由于长期以来靠天养畜,超载放牧或弃牧毁草开荒,再加上管理不善,弃牧毁草开荒,造成1/3的草地不同程度的退化,使草地生产力大幅度下降。因此,超载放牧、弃牧毁草开荒、靠天养畜等是目前我国在草地利用方面存在的主要问题。

【题目】

Bikesharing has swept across China, with an increasing number of people choosing bike riding instead of driving. The bike that the service company provides has GPS or Bluetooth on it, and those bikes can be easily unlocked with a smart phone and left anywhere in public. Bikesharing allows people to borrow a bike from one place and return it at another place easily.

In some cities, we can see more and more people riding this kind of sharingbikes. It's very convenient to use the bikes if you have a smart phone. First, you have to download such an APP on your smart phone. Then what you need to do is to find a nearest bike through the APP, scan the QR code on the bike or connect your phone with the bike over a Bluetooth wireless connection. You will find the bike can be unlocked itself. Then you can enjoy your trip. What's more, the greatest advantage of bikesharing is that you can easily find one and never worry about where to park it. The cost of riding depends on the time that you spend. Normally, every hour you ride, you need to pay one yuan. It doesn't cost so much, does it?

At the same time, some people park the bikes in their own homes. Besides, some people don't value the bikes. Now service companies are trying to solve the problem like being stolen.

Technology and science have changed our social lifestyles. We have to say bikesharing brings us more convenience without doubt. And we also hope that people can not only enjoy it but also put it to good use.
