Bibliography of Environmental Studies in Natural Characteristics and Anthropogenic Influences on the Ganga River

During the second half of the 20th century, the Ganga River ecosystem has been continuously altered by several ongoing anthropogenic processes, accommodating multi-dimensional pressure due to increase of nearly four-fold human population. For solution of any environmental issues of the river, the Earth System Science approach is required to have maximum socio-economic benefits to millions of people living in Indian and Bangladesh. A bibliography containing more than 250 references on environmental studies of the Ganga River was prepared to preserve its ecosystem by providing the baseline support in this regard.

文章从深入分析环境管理的内涵出发,进而提出树立项目管理意识,强化项目管理的概念,说明项目管理在环境管理中的地位和作用,从这个意义上讨论环境管理与项目管理的关系,简述环境保护项目管理的主要环节,达到提高环境管理效能的途径的目的。     

GIS支持下乡镇域土壤肥力评价与分析

在地理信息系统支持下,以鄂南典型红壤丘陵区为例,研究了乡镇域土壤肥力评价的方法和过程,分析了土壤肥力变化原因。结果表明,应用GIS对乡镇域土壤肥力进行评价能克服速度慢、数据更新不方便的缺点,避免乡镇农业决策者主观判断土壤肥力等级的弊病,为生产布局和用地决策提供准确的科学依据。试区土壤肥力与土壤养分、土地利用和区域经济有关,肥力等级有向中等级变化的趋势。     

城市园林绿化用地土壤肥力诊断与综合评价——以广州市长虹苗圃为例

以广州市长虹苗圃为例,在实地调查与采样分析的基础上,首先对土壤肥力各单项指标进行诊断分析,然后采用修正的内梅罗指数对各地块进行土壤综合肥力评价。结果表明长虹苗圃土壤pH值偏低,有机质以及其它主要养分含量缺乏,各地块综合肥力系数大都属于贫瘠水平,其中南区、北区综合肥力明显低于东区。     

美国瑞典日本农药环境管理综述

我国是个农业大国 ,农药的使用量大 ,使用品种多 ,农药对生态环境污染较为严重。长期以来 ,我国的农药环境管理极其薄弱 ,农药环境管理体系不完善。国外一些国家如美国、瑞典、日本等农药管理体制比较健全 ,在农药环境管理方面取得了一些成功经验 ,这对我国建立农药管理体系有很好的借鉴意义。     

关于我国21世纪农业清洁生产的思考

现代工业的出现和工业化进程的不断发展,使生态环境受到污染和破坏。清洁生产因突破了传统的终端污染控制的被动局面,在工业领域得到推广应用。然而,以高度集约化和大量化学物质投入为重要特征的现代农业,所导致的环境污染问题也日益严峻。因此,为达到农业生产与生态环境协调发展的目的,农业清洁生产应成为２１世纪农业发展模式和农业环保策略,其关键是开发绿色农用品,改进农业生产技术。     

Reform,Justice, and Sovereignty: A Food Systems Agenda for Environmental Communication

Food ecologies and economies are vital to the survival of communities, non-human species, and our planet. While environmental communication scholars have legitimated food as a topic of inquiry, the entangled ecological, cultural, economic, racial, colonial, and alimentary relations that sustain food systems demand greater attention. In this essay, we review literature within and beyond environmental communication, charting the landscape of critical food work in our field. We then illustrate how environmental justice commitments can invigorate interdisciplinary food systems-focused communication scholarship articulating issues of, and critical responses to, injustice and inequity across the food chain. We stake an agenda for food systems communication by mapping three orientations—food system reform, justice, and sovereignty—that can assist in our critical engagements with and interventions into the food system. Ultimately, we entreat environmental communication scholars to attend to the bends, textures, and confluences of these orientations so that we may deepen our future food-related inquiries.
