问题 材料分析题

阅读材料,读图回答下列问题。

    普罗旺斯地区位于法国南部的阿尔卑斯山脉至地中海沿岸,因盛产花卉而闻名,南部的茉莉花品质优异。虽然一首江苏民歌《好一朵茉莉花》唱遍世界,但其经济价值远不及法国。茉莉花为亚热带多年生常绿灌木,喜高温,不耐寒,气温低于3℃时枝叶易遭受冻害,适宜的气候条件下一年可开三次花,6至10月为花期。

(1)比较甲、乙两图中0℃等温线的分布差异。

答案

(1)欧洲西部0℃等温线分布的纬度范围比中国高;欧洲西部0℃等温线较为弯曲,北段(西段)大至呈

    南北(东北――西南)走向;南段大至呈东西走向。中国0℃等温线比较平直,大致呈东西走向(东段

    呈东北-西南走向,西段呈东西走向)。

(2)普罗旺斯南部属地中海气候,夏季炎热干燥,光照强烈,利于茉莉花花期生长;冬季温和,无低温

    冻害,利于茉莉花越冬。江苏北部为温带季风气候,南部为亚热带季风气候,夏季高温多雨,冬季低

    温少雨,夏季的梅雨不利于茉莉花花期生长,冬半年寒潮侵袭伴随的低温冻害不利于茉莉花越冬。

Sometimes there doesn’t seem to be enough rain. Other times there is too much. Maybe thereisn’t a lot we can do to control the rain, but there is a lot we can do to reduce problems caused bydifferent rainfall patterns.

A new development at the London Wetland Centre in Barnes solves the problems of managingwater with a “Rain Garden”. We are likely to be hearing about it a lot more often over the next fewyears. The idea is that the garden owner can store rainwater and use it in dry periods. They canreduce the problems caused by extra rain this way.

One of the key problems that the rain garden tries to deal with is the problem caused by toomuch water in the street. In a natural environment, a lot of rainwater is sent back into the air byplants. Much is also absorbed deep into the ground, and flows into streams and rivers. What happensin city environments can be completely different —— a large amount of rainwater flows straight offthe hard surfaces of roofs and roads. The harder the rain, the less likely it will be absorbed into theground —— floods are the result. Rainwater running off roads is often polluted.

The rain garden deals with living plants rather than hard surfaces. Plants are designed to holdwater and release it slowly, either into the ground, to be absorbed by plant roots (and so eventuallyback up into the atmosphere) or to go down into the water table. Not only does the rain gardenreduce the amount of water that flows onto the street, but it helps to clean it because plants are very goodat breaking down pollutants(污染物).
