人教版高中地理必修1全球氣候變化教案
科學(xué)家預(yù)測，就地區(qū)而言，位于低緯度的大部分國家，農(nóng)作物的產(chǎn)量將減少；而位于高緯度的國家，農(nóng)作物產(chǎn)量有可能增加。由于不少發(fā)展中國家位于低緯度地區(qū)，因此，氣候變化的這種區(qū)域差異性，可能會使發(fā)展中國家所面臨的問題更為嚴(yán)峻。板書：3全球變暖將加劇水資源的不穩(wěn)定性與供需矛盾。介紹：全球變暖會影響整個水循環(huán)過程，可能使蒸發(fā)加大，改變區(qū)域降水量和降水分布格局，增加降水極端異常事件的發(fā)生，導(dǎo)致洪澇、干旱災(zāi)害的頻次和強度增加，以及地表徑流發(fā)生變化。隨著徑流減少，蒸發(fā)增強，全球變暖將加劇水資源的不穩(wěn)定性與供需矛盾。轉(zhuǎn)折：既然全球變暖會引起很多不利影響，那么作為人類應(yīng)如何面對這一挑戰(zhàn)呢？這就是我們要討論的第三個問題。板書：三、氣候變化的適應(yīng)對策討論：請大家閱讀結(jié)合教材P53氣候變化的適應(yīng)對策部分討論人類應(yīng)如何面對全球變暖這一問題 呢？

1．國家石油價格上漲，導(dǎo)致依賴于國際石油而建立起來的日本重化工業(yè)的制造成本提高，產(chǎn)品價格相應(yīng)提高，削弱了日本重化工產(chǎn)品在國際市場上的競爭力。2．日元 的大幅度升值，意味著日本產(chǎn)品在國際市場上的價格大幅度提高。例如，同樣的日本產(chǎn)品，如果原來在國際市場上賣1美元，日元升值1倍后其在國際市場上的售價就達(dá)2美元。所以，以國際市場為依托的日本傳統(tǒng)產(chǎn)業(yè)只好紛紛向海外轉(zhuǎn)移。3．自身市場滿足不了發(fā)展需求，國際市場上亞洲發(fā)展中國家和地區(qū)的同類產(chǎn)品具有明顯的價格優(yōu)勢。所以，日本企業(yè)在其國內(nèi)發(fā)展的空間很小。4．勞動力價格高反映為產(chǎn)品的價格高，而勞動力數(shù)量又滿足 不了企業(yè)進(jìn)一步擴展對勞動力的需求。所以，日本從事傳統(tǒng)產(chǎn)業(yè)的國內(nèi)企業(yè)生產(chǎn)受勞動力價格和數(shù)量的雙重制約。5．促進(jìn)日本企業(yè)生產(chǎn)的區(qū)位選擇向國土的南、北部和海外擴展。6．“技術(shù)立國”的政策明顯對傳統(tǒng)產(chǎn)業(yè)在國內(nèi)生產(chǎn)不利，即企業(yè)生產(chǎn)要么向知識技術(shù)密集型轉(zhuǎn)換（這需要大量的投資），要么轉(zhuǎn)向海外。

1．歸納珠江三角洲發(fā)展基塘生產(chǎn)有利的地理條件。珠江三角洲地勢低平，河網(wǎng)密布，降水充沛。北回歸線從珠江三角洲的北部穿過。珠江三角洲地區(qū)發(fā)展基塘農(nóng)業(yè)生產(chǎn)有利條件可以結(jié)合材料，歸納為三個方面：地形、氣候、市場（當(dāng)?shù)睾秃Ｍ猓?．基塘生產(chǎn)將哪些產(chǎn)業(yè)聯(lián)系起來?哪些副產(chǎn)品(或廢棄物)被充分利用起來?這種聯(lián)系對農(nóng)村經(jīng)濟發(fā)展有什么作用?基塘生產(chǎn)環(huán)節(jié)將種植業(yè)（桑、蔗等）、養(yǎng)殖業(yè)（養(yǎng)蠶、養(yǎng)魚）、工業(yè)（絲廠、糖廠）等幾種產(chǎn)業(yè)緊密的聯(lián)系在一起。在此環(huán)節(jié)中，塘泥、蠶沙（蠶屎）、蠶蛹、繅絲、濾泥、蔗葉等副產(chǎn)品被充分的回收利用。養(yǎng)蠶業(yè)、蔗糖加工業(yè)同塘魚養(yǎng)殖業(yè)緊密結(jié)合，作為一種綜合的經(jīng)營，幾者之間相互依存、相互促進(jìn)、揚長補短，有機地循環(huán)聯(lián)系起來?；旧辖鉀Q了桑、蔗的肥料和蠶、魚的飼料問題。不僅養(yǎng)蠶、蔗糖加工和養(yǎng)魚生產(chǎn)穩(wěn)定，而且成本也大大降低。
人教版高中地理必修2人口合理容量教案
（1）請同學(xué)們結(jié)合日常生活實例和教材分析說明人類要在世界各地消除貧困并保持人口的合理容量任務(wù)的艱巨性？（2）采取何種措施才能更好的解決這一問題的出現(xiàn)？教師總結(jié)（1）現(xiàn)實中的人口問題（如人口過快增長、人口城市化和人口老齡化等）引發(fā)了嚴(yán)重的資源問題和環(huán)境問題。①發(fā)達(dá)國家的人均消耗資源量很大，索取資源和轉(zhuǎn)嫁有害生產(chǎn)的地域超出了本國的范圍。②發(fā)展中國家不僅人口數(shù)量多，人均消費水平低，而且一些國家的人口仍在快速增長。若在現(xiàn)有的經(jīng)濟基礎(chǔ)上，把發(fā)展中國家人均生活質(zhì)量提高到與發(fā)達(dá)國家相當(dāng)?shù)乃?，所引發(fā)的資源短缺和環(huán)境問題將會相當(dāng)嚴(yán)重，解決的難度也很大。（2）I就整個世界來說：①國際社會要倡導(dǎo)各國，尤其發(fā)展中國家要盡最大可能把人口控制在合理的規(guī)模之內(nèi)；②建立公平的秩序，保證大多數(shù)人擁有不斷追求高水平生活質(zhì)量的平等權(quán)利。
