论"风水"精华与生态环境保护

风水是人们追求理想生存环境的一门学科,它在中国传统文化中影响极大,其理论中体现了许多现代环境学的先进思想。通过对风水学的再研究,发现在很早以前的风水学中就有可持续发展的思想,本文从科学的角度对风水学中的“气”,“脉”,“形”进行重新诠释,并叙述了风水与生态环境保护密不可分的关系。     

北环铁路地质安全性研究

影响铁路工程安全的因素有很多,最基础的因素应是工程的地质安全性。针对北环铁路所处的特殊工程地质环境,分别从黄土特性、人类活动、地震液化和土动力学性质等几个方面,论述铁路的地质安全性,分析铁路工程与地质环境的相互作用,研究人类活动对工程地质环境的改变及其影响程度,可以认为:黄土对工程安全的影响不仅仅在于其湿陷性,更在于对其的认知和软化、触变特性;人类活动的负面作用也同样影响着地质的安全作用,不仅改变其原来地貌,也改良了土的安全性质,铁路附近的饱和软黄土就是人类活动改造地质环境的结果;土的动力学特性对工程安全起着潜移默化的作用;最后指出铁路工程的安全性是建立在地质安全性的基础上。     

试论公民环境权的性质

公民环境权是在环境危机产生后才愈加受人关注.本文通过对公民环境权的定义的探讨,对公民环境权的性质进行剖析,并且认为公民环境权是一项法定权利,它是由生存权发展而来的一项基本人权.但期待高位阶的法律做出更为明确的规定.     

对人的认识和假设是人机工程学的基石

人机系统是以人为中心的系统，对人的认识和假设是人机工程学的基石。本文提出了人是生物人、经济人、社会人的复合体的新观点。由于对人的特质的认识还存在着许多“盲区”和“误区”，这就给人机工程学的完善和发展带来了许多不定因素和困难     

LAKE MICHIGAN DIVERSION - STREAM QUALITY PLANNING1

ABSTRACT: By United States Supreme Court action, the diversion of water from Lake Michigan and the Lake Michigan Drainage Basin in the Metropolitan Chicago Area is regulated at an annual maximum rate of 3,200 cfs. Approximately 1,700 cfs of this diversion is used for water supply, and the remaining 1,500 cfs consists primarily of stormwater runoff with lesser amounts of direct lake diversion, such as lockage and leakage, navigational makeup water flows, and discretionary diversion needed to maintain water quality standards in the Metropolitan Sanitary District of Greater Chicago's basic waterways. In order to assess the schedule of its discretionary diversion needs, the District, using a computer model of its basic waterway system, has calculated the minimum discretionary diversion requirements for projected water quality conditions as successive elements of the District's water pollution control program are completed. The results of these analyses can be used as a basis for developing plans for future allocations of the limited supply of Lake Michigan water to other uses such as domestic water supply, when and if such supplies become available.     

自然资本,科技进步与经济的可持续增长

自然资本存量保持基本恒定,被国际学术界认为是维持经济可持续增长、实现可持续发展的基础。本文尝试性地将自然资本引入反映投入产出关系的生产函数,探讨了科技进步、自然资本消耗与经济增长之间的关系,并指出了发展进程中应遵循的原则。     

Exposing violences: Using women's human rights theory to reconceptualize food rights

Exposing food violences – hunger,malnutrition, and poisoning from environmentalmismanagement – requires policy action thatconfronts the structured invisibility of theseviolences. Along with the hidden deprivation offood is the physical and political isolation ofcritical knowledge on food violences and needs,and for policy strategies to address them. Iargue that efforts dedicated on behalf of ahuman right to food can benefit from thetheoretical analysis and activist work of theinternational Women's Rights are Human Rights(WRHR) movement. WRHR focuses on women andgirls; the food rights movement operates onbehalf of all people, with an emphasis on thepoor. Both attend to the protection of bodilyintegrity against physical and psychicviolences. Both cope with bodily violences thatare socially privatized and spatiallysegregated from public institutions of relief,that is, they are tacitly omitted from publicdiscourse and purview. Most typically, but notexclusively, these violences unfold in privatehousehold space. Both rights movements mustmobilize political rights to demand economicand social rights and security. I introduce theUnited Nations' early Declaration (1948) andCovenant (1966) language on the human right tofood and review problems of household accessand grassroots engagement that are ``writteninto' this early documentation. An abbreviatedoverview of the WRHR movement describes how thepublic/private and economic/political rightsdichotomies have been critiqued andre-formulated. A case study set in Polandacross the transition from (more) communist to(more) capitalist political economies attemptsto illuminate the discussion through agrounded example.     

HYDROLOGIC STAGE PERIODICITY OF THE MISSISSIPPI RIVER BEFORE AND AFTER SYSTEMATIC CHANNEL MODIFICATIONS1

ABSTRACT: Periodic flood disturbance is a well known controlling factor of in channel and floodplain ecosystem function. However, channel manipulations during the last century have potentially altered hydrologic fluctuations, and thus ecosystem function. We examined temporal river stage hydrology, through autocorrelation analysis, at seven gauges along the Mississippi River to quantify flow periodicity and effects of systematic channel modifications on flow periodicity. Intraannual variation follows a strong one‐year cycle of six months higher flow and six months lower flow for the entire Mississippi River drainage, with precipitation as a driving force. Interannual hydrologic variation differs between the upper and lower river segments. A clear quasi‐biennial oscillation pattern was evident throughout the lower river section. The effect of channel alterations was a decreased magnitude of differences between lower and higher flows. The upper section, however, suggests a 12‐to 14‐year periodicity prior to alterations and a decreased duration of lower flow years following systematic modifications. Interannual variograms clearly depict very different temporal hydrology between the upper Mississippi River and the lower Mississippi River, suggesting the simple transfer of knowledge from one segment to the other oversimplifies the complexity of a large river system.
