Environment as the Stage for Economic Actors

The relative importance of economics and environment in debate may soon be reversed due to the influence of three fac- tors. Firstly, in the global economy it is hard to hide the unwanted products of economic processes. Secondly, huge advances in sci- ence will reduce the imperfect knowledge of markets, making some monitoring and analyzing tools show the design of sensible and equitable livelihood in communities, which is more important than the motivation of maximising profits for some individuals or firms. Thirdly, China, as the last major player on the planet to take on economic growth, comes from traditions fundamentally differ- ent from those economies that have experienced the Industrial Revolution previously. Its challenges with sustainability and en- vironmental conservation predate Western economics by millennia, and it is implementing policies domestically and starting to work on the world stage that acknowledges that the surroundings are the host for any economic and socio-political system.     

企业环境行为:环境政策研究的微观视角

企业环境行为是是企业面对来自政府、公众、市场等方面的压力．而采取的宏观战略和制度变革、内部具体生产的调整等措施和手段．是环境政策效果的具体体现。政府、公众和市场压力在不同阶段发挥着不同的作用。在工业绿色化的初级阶段以政府压力为主。随着公众和企业更多地参与到环保行动中来．来自市场及社区的压力逐渐成为企业环境行为的主导驱动力量。我国正处于工业化加速阶段．环境问题突出．必须积极开展对企业环境行为的研究，探求环境压力与企业环境行为转变的内在关系．找到促进企业改善环境行为和表现的最优方式，为我国环境政策的制定提供决策支持。     

江西省兴国县土壤侵蚀动态监测研究

介绍发应用遥感技术和调查资料编制的江西省兴国县三个时期（１９５８，１９７５，１９８８年）的土壤侵蚀动态监测图。结果表明，建国以来，该县水土流失的动态变化基本上呈抛物线的态势发展，目前水土流失面积在缩小，程度在降低，总的趋势向好的方向发展。

气候变化和人类活动对历史时期黄河决溢的影响

本文统计分析了历史时期黄河决溢的变化。并从自然和人为因素两方面探讨其原因和规律。认为在湿润的气候时期黄河决溢频率增高,其原因是本地区高强度的暴雨造成了黄土高原严重的水土流失,从而使黄河中下游大量的泥沙沉积。人类特别是小冰期以来加强了对黄土高原的开发,破坏了原先的植被,从而造成了严重的水土流失,这是小冰期以来黄河决溢次数远远高于其它时期的主要原因。作者还认为在下世纪高温环境到来之际,黄河决溢的危险性大大增加。
