问题 综合

读图,回答下列问题。

(1)描述图示地区主要地形区的分布状况。(6分)

(2)陕西洛川是我国苹果主产区之一,分析其优越的气候条件,并说出该区发展苹果种植业的环境效益。(4分)

(3)甲区煤炭资源丰富,指出其运往上海最经济合理的运输方式,并说明理由。(4分)

(4)水资源短缺是京津区工农业发展的限制性因素,分析其原因并提出相应的解决措施。(6分)

答案

(1)东部是华北平原,地势较平坦;中部是太行山脉,呈东北—西南走向;西部是黄土高原,地表支离破碎、千沟万壑。(每点2分,共6分)

(2)气候优势:洛川产区地处黄土高原,海拔高,光照充足,利于营养物质的合成;距海较远,气候大陆性强,晴天多;昼夜温差大,利于糖分积累;地处暖温带(中纬度),适合苹果生长。(任意两点,得2分)

环境效益:涵养水源,保持水土;防风固沙。(2分)

(3)方式:铁路—海运联运。 ( 1分)

理由:甲区地处内陆;上海临海;运距较远;煤炭运输量大;对时间要求不高;

铁路-海运联运,运量较大,运费较低,适宜远距离运输大宗货物。(任意三点,3分)

(4)原因:温带季风气候,年降水量小且集中在夏季,水资源总量少且时间分布不均;人口众多,工农业发达,用水量大;水污染严重;水资源利用率低(任三点,3分)

措施:节约用水;改进农业灌溉和工业生产技术,提高水资源的利用率;发展节水工农业(种植耐旱作物);治理水污染,实现水资源的循环利用;修建水库;修建跨流域调水工程。提高水价。产业转移和结构优化。(合理即得分,每点1分,共3分)

本题考查我国的区域地理。(1)图示为我国的华北地区,西部为黄土高原,海拔高,千沟万壑;东部为华北平原,地势低,平坦;以中部的太行山脉为界。(2)苹果种植的气候条件主要从气温、降水、温差和光照等方面分析;注意环境效益,主要从山区的水土流失和干旱地区的荒漠化治理角度分析。(3)由于铁路的运输能力有限,而煤炭资源的运量大,故合理的运输方式是先从甲地采用铁路运至沿海港口,再走海运。(4)华北地区的缺水从自然原因:降水少,地表径流总量少,且季风气候影响,降水的季节变化大;人为原因主要从用水量和污染等方面分析。采取的措施主要从开源、节流、治理水污染等角度分析。

Megan's Library of Love book drive began in 2006, in memory of a student who passed away. The       to send books to a school      was created by Megan's classmates at Cedar Grove-Belgium Middle School as a tribute(悼念)to her.

Students earn the money for postage by writing letters to local      .The fifth graders also have the      of labeling every book with a Library of Love sticker(标签),        the books into categories(类别), and      all the books for shipping.
In the two years since the Library of Love      began, students have collected over 5000 newly purchased books to send to schools in need. In 2006, 3419 books were sent to St. Bernard's Parish to help      their school library after Hurricane Katrina destroyed the community. In 2007, 1613 books were sent to White Mountain School in Alaska, who      their high school in a fire. Students look forward to sending the gift of      to other schools
