教具准备：多媒体图片教学方法：讲授法、案例分析法、探究教学法等教学过程：导入：随着世界人口的持续增长和经济的迅速发展，人类对自然资源的需求量越来越大，而自然资源的补偿、再生和增殖是需要时间的。
对自然资源的利用一旦超过了极限，就会出现资源问题。
目前，资源短缺与人口增长、经济发展对资源需求之间的矛盾，已成为世界性问题。
一、自然资源1．概念：指在一定的经济技术条件下，自然界中可以被人类生产与生活利用的物质和能量的总称。
2．意义：它们是支持人类生存、支持社会可持续发展所不可缺少的物质基础。
3．分类：非可再生资源可再生资源。
二、淡水资源短缺(一)世界淡水供应与需求1．世界淡水供应少（1）可以用的水资源少①在全球水储量中，淡水只占2．53％。
②所有淡水中99％难以直接利用。
i淡水中绝大部分储存在两极冰帽和大陆冰川中，占淡水总量的86％，因地处偏远，难以获取；ii还有12％的淡水为地下水，必须凿井提水方能获取。
iii在无人区或人烟稀少地区降水所形成的地面流水，也未能被人们利用。
③人类最容易获取的是江河湖沼中的水。
（2）淡水资源在陆地上分布很不均匀受气候等地理条件的影响，巴西、俄罗斯、加拿大、美国等国水资源丰富。
北非和中东很多国家降雨量少，蒸发量大，每年总水量和人均水量都低。
（3）水资源浪费和污染严重人们在利用水资源过程中，有时采取了不合理的开发与管理措施，以致浪费水的现象相当普遍，加上许多地方出现水体严重污染，使原来不充足的淡水资源更为紧缺。
2．世界淡水的需求量大生产需求工业用水（1）人类对水的需求农业用水生活需求）各国各地各种用水量以及它们分别在总用水量中所占比例差别显著。
．从总水量来看，亚洲、北美、欧洲多，大洋洲、中美、南美洲和非洲少。
其影响因素主要有径流地区不协调，水资源的有效利用率低。
2．从各部门的用水比例来看，欧洲和北美的用水比例由高到低依次为工业、农业、生活，而非洲、亚洲、中东的用水比例由高到低依次为农业、工业、生活，且农业用水比例远远高于工业。
这主要是由各地区经济的部门结构来决定的。
3．从生活用水的角度看，欧洲、北美、大洋洲、南美洲的比例较高，非洲、亚洲和中关的比例较低。
这主要与当地居民的生活水平有关。
（3）世界总需水量增长很快随着人口不断增加，工农业生产发展，以及其他社会用水扩大，供需矛盾非常突出。
3．水资源短缺的影响（1）水资源短缺制约着经济发展，影响着粮食产量，对生态环境产生不良影响，并且直接损害人们的身体健康。
（2）为争夺水资源，在一些地区还引发国际冲突。
如，水资源短缺已成为中东、非洲等地区国家关系紧张的重要原因之一。
同一条河流的上游与下游国家，常因为水的问题发生争执。
(二)中国淡水供应与需求1．总特点：中国水资源总量丰富，但人均水资源量很少。
2．地区分布极不平衡总规律：由东南向西北递减（图3．2)。
⑴长江及其以南地区水资源丰富，但在部分人口稠密地区，由于河流水污染与湖泊富营养化等原因，使水质不能符合要求，也存在淡水资源短缺问题。
⑵长江以北外流河区的广大地区水资源相对较少，黄河、淮河、海河流域是我国水资源最为紧缺的地区。
⑶内流河区属于地广人稀、经济欠发达地区，生态环境脆弱，单位土地面积水资源占有量少，经济用水大量挤占生态环境用水，为该区域带来了生态环境问题。
3．时间分配不均我国降水量在时间分配上，年际变化大，年内分配不均，更给水资源的利用带来困难。
4．我国水资源供需矛盾突出（1）我国农业、工业和生活等方面对水的需求量急剧增长。
在许多地区，水资源的开发利用已经超过了水环境的承受能力。
2000年全国总用水量已增至5497亿立方米，与1949年相比，净增4．34倍。
（2）由于自然和社会因素的综合影响，我国水资源供需不平衡，农业和城市缺水状况已备受关注。
缺水已经成为对工农业生产有重要影响的问题。
目前全国有效灌溉面积约占全国耕地面积的51．2％，近一半的耕地得不到灌溉。
全国600多个城市年有近400个城市缺水，其中严重缺水城市达130多个。
?⑴水多：共涝灾害多，是部分地区发展的心腹大患。
据世界银行估计，中国每年在洪涝灾害上的损失平均为100亿美元，其中洪水占三四成，涝灾占五六成。
⑵水少：供给和需求不平衡。
河道外用水较多，造成河水断流，地下水位下降。
⑶水脏：水环境污染、水质下降等。
⑷水浑：包括水土流失、沙尘暴等引发的一系列水环境问题。
三、耕地日渐减少(—)世界耕地需求趋势全世界可耕地总面积为29．5亿公顷，其中容易开垦的部分已被耕种，面积为15．4亿公顷。
其余虽有潜在的被开垦的可能性，但是或由于土壤肥力水平不高，或由于通达性受到限制，必须有较大投入才能有效利用。
随着世界人口的增长，人类正在面临着越来越严峻的耕地资源不足的问题。
3．4，分析以下问题。
1．依据世界可耕地总面积、世界人口、按现有生产水平所需耕地面积三条曲线，分析世界土地资源供求关系的前景。
点拨：随着人口的增加，人地矛盾将越来越尖锐。
目前人类已经面临耕地资源不足的困境，随着时间的推移，这种供求矛盾的矛盾将进一步突出。
2．如果进一步开垦土地，使世界耕地面积处于动态平衡(如虚线所示)，土地资源供求关系的前景将怎样变化?点拨：从图3．4可以看出，开垦土地只能把这样的困境延缓一段时期。
更何况可供开垦的土地越来越少，农业生产水平也不可能在短时期内大幅度提高。
3．如果使现有农业生产水平翻一番、翻两番，世界土地资源前景将怎样变化?点拨：从图3．4可以看出，如果使现有农业生产水平翻一番、翻两番，世界土地资源能把这样的困境延缓一段时期。
4．你认为开垦土地、使农业产量翻番的可行性怎样?为什么?点拨：能够在一定程度上缓解土地资源的压力，但是不是根本的解决方案，因为从图3．4提供的信息说明，耕地供需矛盾实质上是人地矛盾，控制人口增长是解决此矛盾的关键。
(二)中国耕地资源面临的压力1．耕地面积总量大，但人均占有量小中国土地资源中耕地面积有1．28亿公顷，约占总土地面积的13．7％。
由于人口众多，人均占有耕地不足0．1公顷，仅为世界人均耕地面积的45％。
2．耕地的地理分布很不均，人均耕地水平也存在很大差别（1）我国耕地的地理分布很不均匀。
由于自然条件、历史发展和人口密度等因素的影响，耕地中日8.4％分布在东南半壁，11.6％分布在西北半壁。
（2）人均耕地水平也存在很大差别只有黑龙江、内蒙古人均耕地多于0.3公顷。
自然条件较好和生产水平较高的地区，如上海、北京、天津、湖南、浙江、广东和福建等省市，人均耕地面积小于0.07公顷。
3．随着经济的发展，非农业建设用地增长迅速，加剧了人均耕地的减少近年来，我国非农业建设用地增长迅速，城市建设、能源、交通、水利、工矿建设用地均不断增加，占用了不少耕地，使得人均耕地面积日益减少(图3．5)。
?人口的增加，我国人均耕地面积逐步下降。
到了近代，可开垦的土地有限，加之各种建筑用地面积加大，而人口仍然快速增长，导致人均土地面积将进一步下降。
目前我国人口仍然在增长，后备的耕地资源有限，城市、工业、交通等还要占用耕地，所以我国人均耕地面积仍然有下降的趋势。
．通过查阅图书、互联网或实地调查，了解学校附近地区近年来耕地被占用的情况，及其对粮食生产的影响。
根据实际情况可以由教师提供资料的方式进行，如果条件允许，可以到当地土地局或实地进行考察，获得有效数据。
2．针对此种情况，建议采取什么对策?4．耕地中高产稳产田占1／3左右，低产田约占1／3由于人口增加，为了满足粮食供应的需求，人们不断增加土地利用强度，致使土地退化严重，加上由于不合理的灌溉和施用农药等，使耕地受到严重的污染，更加剧了耕地不足的局面。
四、一些矿产濒临耗竭1．世界矿产资源现状：矿产资源是人类生产资料与生活资料的重要来源。
矿产资源的特性之一是其非可再生性，但全世界消费矿产资源的数量却呈现快速增长的趋势。
占世界人口1／5的发达国家消费了世界3／4的矿产资源，广大的发展中国家的矿产消费量只占世界的1／4。
随着矿产资源消费量的急剧增长，有些矿种发生短缺甚至耗竭。
2．我国矿产资源的紧迫性表现：⑴中国矿产资源总量大，居世界第三位，而人均占有量低于世界平均水平。
⑵矿产资源中富矿少，贫矿多，加之开采中采富弃贫，使矿产品位下降。
⑶矿产资源的地区分布不平衡，矿产品的加工消费区集中在东南沿海地区，而矿产资源主要富集在中部或西部地区。
到目前为止，我国45种主要矿产的探明储量有相当部分不能满足经济发展的需要，到2020年，资源保证程度更低，特别是绝对需求量大的石油、铁、铜、铝、硫、磷等重要矿产缺口大，矿产资源供需矛盾加剧。
源短缺的严重性、紧迫性，从而为树立节约矿产资源的意识和行为奠定基础。
