黑龙江省可持续发展与21世纪减轻地质灾害策略分析

黑龙江省地质、地貌、气候、水文条件复杂,是地质灾害的多发区;且随着经济的发展,人类经济工程活动诱发的地质灾害也在逐年增加.本文分析了黑龙江省地质灾害的类型、成因、分布及危害;论述了地质灾害与可持续发展的辩证关系;并为促进本省可持续发展提出了切合实际的减灾对策.     

透视我国环境与资源法制建设

我国自改革开放以来在构建环境与资源保护法律体系方面取得了可喜的成绩,但也存在一些问题。主要表现为:可持续发展战略尚未成为我国环境与资源保护立法的指导思想,我国的环境与资源立法不能完全适应社会主义市场经济的要求和社会发展的需要,我国关于环境与资源的法律法规之间不相统一。造成上述问题的原因有外部因素和内部因素,同时我国的具体国情又使它们更具特殊性。为了有效地解决这些问题,我国须在加强环境立法、健全现有制度、协调内部功能等方面进行不懈的努力。

滇、桂、粤、闽、台灾害链讨论

由于对洪水、台风和巨大风暴潮的长期预测尚有一定困难，因之需要多学科进行综合研究。本文通过对滇、桂、粤、闽、台地区历史上大震后同年或次年发生上述重大气象灾害的事实，讨论了灾害链的预测，同时也讨论了灾害链的形成机制，包括构造活动、北回归线效应以及孟加拉湾大桥活动的双重后果。文中还提出了4条减灾对策。     

Food Health Policies and Ethics: Lay Perspectives on Functional Foods

Functional foods are a challenge tofood health policies, since they questioncentral ideas in the way that food healthpolicies have been developed over the lastdecades. Driven by market actors instead ofpublic authorities and focusing on the role ofsingle foods and single constituents in foodsfor health, they contrast traditional wisdombehind nutrition policies that emphasize therole of the diet as a whole for health.Sociological literature about food in everydaylife shows that technical rationality co-existswith other food related rationalities, such aspractical and economic rationalities, socialand relational rationalities, and symbolicrationalities that influence citizens' ordinaryeating habits. An examination of lay views onexpert knowledge about food and health showthat skepticism exists with respect to thebasis of and balance of expert advice. Critical points with respect to how functionalfoods may influence routines in the populationswith relevance for public health include thefact, that they promote a way of thinking offood and health that is in conflict withwell-established practical ways of ensuring abalanced diet.

Simulation and control strategy for the variational influent of WWTP

With the development of activated sludge model, the simulation software for the design and operation of wastewater treatment plant （WWTP） was produced and has been widely used. The dynamic change of the quality and flow of influent are major factors causing the unstable operation of wastewater treatment process. As a basic model, ASMI model was used for the simulation of activated sludge process, and double exponential model was selected for the simulation of secondary sedimentation tank. The influences of influent change to the aeration tank and secondary sedimentation tank were investigated, and the relationship among influent change, the quality of effluent and the level of sludge blanket in secondary sedimentation tank was established. On the basis of the simulation results, the operation of the WWTP could be adjusted under the dynamic change of the influent. Furthermore, the controlling strategy combined the feed-forward on the influent flow and the feedback on the level of sludge blanket in the secondary sedimentation tank was studied.
