从洞庭湖演变历史的回顾入手，讨论了洞庭湖演变对湖区生态环境的影响，认为湖体演变带来了诸如湖泊温暖效应降低、调蓄功能减退、洪涝灾害频繁、土壤潜育化严重，血吸虫病流行，以及生物资源破坏等一系列生态环境问题，强调了开展湖区生态环境监测和研究的重要性，并提出兴建长江流域生物工程。     

pH、ORP制约的产酸相发酵类型及顶级群落

由于利用效果存在一定差异，不同产酸相发酵类型的末端产物作为产甲烷细菌的底物，影响整个二相厌氧生物处理系统的稳定、高效运行。pH、ORP作为产酸相系统中的非生物因子，在一定程度上影响产酸相发酵类型的形成。本实验采用连续流搅拌槽式厌氧反应器（CSTR）考察并分析了特定pH、ORP组成对产酸相发酵类型决定情况，同时以种群生态学理论为基础，确立了受pH、ORP制约的不同发酵类型的顶级群落及优势种群。     

Environmental performance optimization using process water integration and Sustainable Process Index

Water integration studies have focused on reducing the amount of water used by a process on the assumption that environmental impact is reduced through efficient water reuse. However, the environmental impact of retrofitting the water network through the installation of pumps and pipes and energy for their utilization which may even lead to a network with a higher environmental cost as measured using a more comprehensive metric, is rarely, if at all, considered. Using the Sustainable Process Index (SPI) as a means of measuring environmental impact, this study addresses the question on water integration and environmental impact and shows that there is a balance that must be struck between water savings and water network modifications.

上海地区的湿地资源及其保护

介绍了海地区的湿地类型、分布、湿地资源及其利用与保护，提出了加强湿地研究的重点领域。上海地区自然湿地面积为４３００９ｈｍ＾２，以海滨沼泽为主；人工湿地以稻田为主，约为２５００００ｈｍ＾２，湿地中的动，植物资源，土地资源相当丰富，是上海地区最重要的自然资源，目前，上海的湿地利用以发展农、林、渔业为主，工程利用率则呈逐年增加的势头。加强对湿地资源的动态研究，对湿地的环境功能，合理利用与保护模式及人类活     

Formulating an ecosystem approach to environmental protection

The U.S. Environmental Protection Agency (EPA) has embraced a new strategy of environmental protection that is place-driven rather than program-driven. This new approach focuses on the protection of entire ecosystems. To develop an effective strategy of ecosystem protection, however, EPA will need to: (1) determine how to define and delineate ecosystems and (2) categorize threats to individual ecosystems and priority rank ecosystems at risk. Current definitions of ecosystem in use at EPA are inadequate for meaningful use in a management or regulatory context. A landscape-based definition that describes an ecosystem as a volumetric unit delineated by climatic and landscape features is suggested. Following this definition, ecosystems are organized hierarchically, from megaecosystems, which exist on a continental scale (e.g., Great Lakes), to small local ecosystems.Threats to ecosystems can generally be categorized as: (1) ecosystem degradation (occurs mainly through pollution) (2) ecosystem alteration (physical changes such as water diversion), and (3) ecosystem removal (e.g., conversion of wetlands or forest to urban or agricultural lands). Level of threat (i.e., how imminent), and distance from desired future condition are also important in evaluating threats to ecosystems. Category of threat, level of threat, and distance from desired future condition can be combined into a three-dimensional ranking system for ecosystems at risk. The purpose of the proposed ranking system is to suggest a preliminary framework for agencies such as EPA to prioritize responses to ecosystems at risk.
