問題：1、對(duì)田納西河流域進(jìn)行開發(fā)能產(chǎn)生哪些方面的效益？2、如果只 提高土地利用程度，是否能保證其他方面的效益不受影響？如果受影響分別說明產(chǎn)生了什么后果？應(yīng)如何治理？這體現(xiàn)了地理環(huán)境的什么特性。（學(xué)生讀課文歸納總結(jié)）讀問題研究內(nèi)容，思 考下列問題1、 阿斯旺大壩位于哪個(gè)國家？它的建立為該國農(nóng) 業(yè)生產(chǎn)提供了哪些有利條件？2、 阿斯旺大壩的建立帶來了哪些經(jīng)濟(jì)效益？又產(chǎn)生了哪些不利影響？3、 我們應(yīng)如何評(píng)價(jià)這一工程利與弊？它對(duì)我國三峽大壩的建設(shè)有什么借鑒意義。同學(xué)們，通過本課的學(xué)習(xí)我們已深切地感受到河流流域的綜合開發(fā)給我們的生活帶來了巨大的改變，但我們更應(yīng)看到人類的 經(jīng)濟(jì)活動(dòng)對(duì)生態(tài)環(huán)境產(chǎn)生的不利影響，怎樣才能趨利避害，造福人類，這是我們每個(gè)人都應(yīng)思考的問題。
人教版高中地理必修3森林的開發(fā)和保護(hù)教案
角色扮演：學(xué)生扮演政府官員、熱帶叢林土著居民、 世界環(huán)保組織官員、開發(fā)商等角色，從角色的立場討論亞馬孫河流域熱帶雨林的開發(fā)活動(dòng)規(guī)則: 每個(gè)小組認(rèn)領(lǐng)一種角色，用5分鐘的時(shí)間討論和整理思路，然后推薦一位代表做中心發(fā)言，小組的其他同學(xué)可以隨時(shí)補(bǔ)充。發(fā)言時(shí)請(qǐng)說 明所扮演的角色，盡可能多的發(fā)表建設(shè)性意見。如果需要，可以上臺(tái)展示材料【學(xué)生互動(dòng)】 風(fēng)云辯論：雨林破壞誰之錯(cuò)?正方觀點(diǎn)：雨林破壞，亞馬孫地區(qū) 的國家和 居民應(yīng)負(fù)主要責(zé)任反方觀點(diǎn): 雨林破壞，發(fā)達(dá)國家應(yīng)負(fù)主要責(zé)任 【師生小結(jié)】 雨林的開發(fā)，既有發(fā)展中國家經(jīng)濟(jì)的需要，也有發(fā)達(dá)國家國際市場的牽動(dòng)。保護(hù)雨林，是全人類的共同責(zé)任，尤其發(fā)達(dá)國家應(yīng)該承擔(dān)更多的責(zé)任。保護(hù)亞馬遜雨林符合長遠(yuǎn)利益和全球利益。但這與雨林所在地國家的發(fā)展產(chǎn)生了矛盾，如何解決之一矛盾是雨林開發(fā)與保護(hù)的關(guān)鍵。【過渡承轉(zhuǎn)】 綠色和平組織警告說，如果不采取有效措施制止對(duì)森林的破壞，80年內(nèi)熱帶雨林可能完全從地球上消失。開發(fā)還是保護(hù)?這是雨林的兩種前途，也
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)?？陀^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。
