伊犁地区农业生态环境与可持续发展—“1515”工程在伊犁地区的实施及生态环

水土资源的开发和生态环境保护是一对矛盾统一体,如何协调发展是当今环保学科的重要课题。本文在论述了伊犁州“1515”工程和伊犁地区生态环境及开发利用现状的基础上,分析预测水土资源开发的影响,并得出了一些基本的可持续发展结论。     

土地开发对生态环境的影响及其防治对策

环境是一生态系统,它具有自动调节功能,但有一定的限度,超过了限度,会导致生态系统平衡失调。因毁体开荒、开垦草原、围垦滩涂,结果导致生态平衡失调和破坏,造成森林减少、水土流失严重、气候恶化、沙漠化扩大,洪旱灾害频发,使整个生态环境趋于恶化,最终影响到人类自身的生存。本文列举了巴州地区土地开发的现状,分析了土地开发对生态环境造成的影响,并提出了生态环境保护对策与建议。     

在环境保护中开展环境审计的重要作用

工业革命把人类推向工业文明,工业文明刺激人类对资源的无限需求,创造出大量消耗资源、严重污染环境的生产方式,产生了大量的环境污染和生态危机。于是,提高环境质量、开展环境保护、保证经济发展的可持续性的呼声越来越高。环境审计作为环境保护的一种有力工具,在当代经济活动中会越来越发挥其重要作用。本文就环境审计的有关问题作一阐述,以其推动环境审计在我国的发展。     

RESOLUTION OF ENDANGERED SPECIES ACT ISSUES IN PERMITTING TILE PLATEAU CREEK PIPELINE1

ABSTRACT: This paper describes how a hydrologic model proved to be a valuable tool to help interested parties understand impacts to four threatened and endangered fish species in the Upper Colorado River. In 1994, the Ute Water Conservancy District initiated permitting and design of the Plateau Creek pipeline replacement. The project was considered a major Federal action and therefore subject to the National Environmental Policy Act. Under Section 7 of the Endangered Species Act, the U.S. Fish and Wildlife Service (USFWS) entered the process to develop a Biological Opinion (BO) and determined that the project could potentially impact the endangered fish in the 15‐mile reach of the Colorado River. The Section 7 consultation was directed by a Core Committee comprised of stakeholders in the Upper Colorado River watershed. Hydrologic modeling became the evaluation tool for comparing flow reductions to USFWS target recovery flows and defining make‐up flow requirements to meet those targets. The Colorado River Recovery Implementation Program was designated to provide the make‐up flows. The USFWS released a final BO in December 1997, approving diversions through 2015. An Environmental Impact Statement for the project was completed and the Record of Decision was issued by the Bureau of Land Management in early 1998.     

A Short History of Food Ethics

Moral concern with food intake is as old asmorality itself. In the course of history, however,several ways of critically examining practices of foodproduction and food intake have been developed.Whereas ancient Greek food ethics concentrated on theproblem of temperance, and ancient Jewish ethics onthe distinction between legitimate and illicit foodproducts, early Christian morality simply refused toattach any moral significance to food intake. Yet,during the middle ages food became one of theprinciple objects of monastic programs for moralexercise (askesis). During the seventeenth andeighteenth century, food ethics was transformed interms of the increasing scientific interest in foodintake, while in the nineteenth century the socialdimension of food ethics was discovered, with theresult that more and more attention was given to theproduction and distribution of food products. Becauseof the increasing distance between the production andconsumption of food products ever since, theoutstanding feature of contemporary food ethics is itreliance and dependence on labeling practices.
