长江三角洲南部“大城市圈振兴”理论的质疑

工业发展和城市化的传统理论，对亚洲的某些具有较高生产力水平，且还在发展中的“大城市圈”不能充分地解释，本文对长江三角洲南部空间经济转为的“大城市圈振兴”理论进行了批判地评论，根据最新的现场调查结果，从根本上对“转为过程”的假说提出质疑，并且提出了更适当的的区域发展战略，此外还证明，关于亚洲大城市带的一般结论，必须建立在对地方性经济变革认识的基础之上。     

三峡库区经济发展评价

当前三峡库区经济发展存在主要产业经济效益低，国有产业亏损大，产业规模小，城镇经济中心作用弱等突出问题．库区开发必需是持久战和持续发展相结合，将库区基础设施建设放在重要地位，搞好资金、行业、所有制之间的优化组合，大力发展第三产业；要准备用几十年的艰苦奋斗，才能赶上全国平均水平．

Material use,economic growth,and the environment

The three broad categories of commodity inputs to the economy are food, fuel, and material, defined as everything else not used for the first two purposes. Material provides physical structure, houses, cars, and packaging; is an important constitutent of modern agriculture in the form of fertilizer and insecticides; and supports the service sector through telecommunications and equipment and paper for our copying machines. The efficient flow of this material is an important factor in the U.S. economy.Correspondence should be directed to Earle B.

论地球系统科学与可持续发展战略科学基础（Ⅰ）

地球系统科学是可持续发展战略的科学。它脱胎于气候系统研究，跨越一系一自然与社会科学，将全球变化与区域变化冶为一炉，所涵差的时间数十年至一二百年，在此时间尺度内，所涵盖的对象基本上是大气、海洋与陆地以及介于其间的物质能量交换过程。陆地最重要、最复杂、受人类活动的影响亦最大，目前未知数亦最多。宜先在跨学科的综合工作上多下功夫，积极推动地系统研究。

An experimental study of sapped drainage network development

In a basin developed on a stream table, effluent subsurface flow supported a channel network that evolved by a combination of headward growth, lateral widening and divide decay. The area occupied by the developing network increased with time. Circularity was used to characterize network evolution which occurred in three phases (initiation, extension and abstraction). Basin sediment discharge declined exponentially with time. Pronounced quasi-cyclic variability was superimposed upon this general trend. Some of the variability was directly linked to changes in the amount of sediment supplied to the channel. The variation of mean network sediment yield (mean sediment discharge scaled by network area) with time adequately described the general decline in sediment discharge as the network evolved.
