人教版高中地理必修3荒漠化的防治教案
1．薩赫勒地區(qū)位于撤哈拉沙漠的南緣。請(qǐng)根據(jù)下面的圖文資料，并聯(lián)系已學(xué)知識(shí)，分析薩赫勒地區(qū)的氣候等自然特征，并說明荒漠化的潛在自然因素。點(diǎn)撥：資料表明薩林勒地區(qū)正處于干旱與半干旱、熱帶沙漠與熱帶草原的過渡地帶；津德爾是其中有代表性的居民點(diǎn)，其月均溫都在22℃以上，甚至達(dá)到33℃，可想而知其蒸發(fā)量是巨大的。在降水方面，這里的年降水量不足500毫米，且基本集中在夏季，特別是7、8兩個(gè)月。以其有限的而且特別集中的降水狀況與其全年的高溫、高蒸發(fā)量相比，確實(shí)是個(gè)容易產(chǎn)生環(huán)境問題的敏感地區(qū)。客觀上，這里就潛在著荒漠化的自然因素，這是本地區(qū)的地理位置和當(dāng)?shù)氐乃疅釛l件所決定的。2．氣候的嚴(yán)酷性決定了薩赫勒地區(qū)的傳統(tǒng)經(jīng)濟(jì)以自給性質(zhì)的游牧業(yè)為主。20世紀(jì)以來，隨著沿岸國家人口和經(jīng)濟(jì)的發(fā)展及本區(qū)交通條件的改善，這里的傳統(tǒng)游牧經(jīng)濟(jì)向商品性的定居牧業(yè)經(jīng)濟(jì)轉(zhuǎn)化。

月球?qū)Φ厍虻囊饬x月球與地球形影相隨，關(guān)系密切。月球?qū)Φ厍虻挠绊懀饕幸韵聨追矫妫?．地球上夜晚的自然照明，主要靠月亮。2．遠(yuǎn)在古代，人們就根據(jù)月相變化的周期，編訂歷法。我國農(nóng)歷月份的安排，是以月相變化 周期為標(biāo)準(zhǔn)的。農(nóng)歷規(guī)定朔為初一，這樣，望就在十五日或十六日。我國人民的傳統(tǒng)節(jié)日，像春節(jié)、中秋節(jié)就是按農(nóng)歷的月日計(jì)算安排的。3．由于地球表面各處所受月球和太陽引力的不同，地球上的水體產(chǎn)生了明顯的潮汐現(xiàn)象。4．月球是人類星際航行的第一站。已知月球表面有多種寶貴礦藏；重力較小；沒有大氣層，利用太陽能的條件較好。如何利用月球的特殊環(huán)境，開發(fā)月球的資源，以及如 何利用月球作“碼頭”，使人類更好地研究宇宙，這將是月地關(guān)系的新篇章。
