土壤重金属污染对蚯蚓（Opisthopora）影响的研究

研究了重金属污染区蚯蚓的群落结构、污染指示种类、以及污染影响的毒理指标．结果表明：随着重金属污染程度的增加，蚯蚓种类减少，蚯蚓体内重金属元素富集量增加．蚯蚓毒理实验表明：Ｃｄ中毒后过氧化物同工酶活性增加，脂酶同工酶活性减弱．Ｐｂ中毒后蚯蚓过氧化物酶和脂酶同工酶活性均增加．     

Effect of sulphadimethoxine contamination on barley (Hordeum distichum L., Poaceae, Liliposida)

Animal wastes from intensive farming are generally collected for field fertilisation. They may contain drugs that can become soil pollutants. To evaluate the possible effects of such contamination in terrestrial systems, sulphadimethoxine has been subjected to laboratory tests (in vitro, synthetic medium, and soil) using seeds of barley (Hordeum distichum L.). The drug suppressed normal post-germinative development and growth of roots and leaves in both test conditions; this effect was dependent on the bioaccumulation rate, which was higher on synthetic medium than in soil. Bioaccumulation was higher in roots than foliage and this was markedly evident in soil and, in particular, in soils with a low humus content. The environmental risk of sludge application on soils and the possible contamination of food chains are discussed.     

用CARIX工艺去除饮用水中硝酸盐的改进研究

针对硬度低而硝酸盐含量高的原水,采用阴离子交换柱研究了用改进型ＣＡＲＩＸ工艺提高了对于下水中硝酸盐的去除,除盐过程中,水中硝酸根和硫酸根等阴离子被碳酸氢根离子置换;再生阶段,用二氧化碳和氧化镁粉末,使树脂转变为重碳酸盐型。     

干旱与半干旱地区土地生产潜力的测定──以新疆阜康县为例

本文探讨了一个通过土壤有效水分含量来确定土地等级和土地生产力的方法。这个方法采用倍增参量形式来确定土壤有效水分。其变量包括潜水位、土层厚度、土壤质地、坡度和盐分。此项研究证明用这种方法获得的土地初级生产力与实测值比较一致。因此，我们可以在类似环境下用这种方法估测土地生产潜力。     

论长江上游水土保持与农业持续发展

长江上游广大山丘区社会发展的历史证明：水土流失严重破坏了人类赖以生存的水土资源，影响了当地农业生产的发展。从１９８９年开展实施的长江上游水土保持重点防治工程，６年来以其显著的经济、生态和社会效益说明：水土保持不仅控制土壤侵蚀，改善生态环境，而且维护了自然资源的永续利用，成为支持长江上游山丘区农业持续发展的重要基础工程。     

浦东新区大气气溶胶中碳颗粒的分布规律

采用元素相关性分析方法，找出浦东新区大气气溶胶中碳颗粒的污染源，确证该区大气中碳颗粒主要来自煤的燃烧。同时初步找出浦东新区大气中碳颗粒污染的时空分布和粒径分布规律，为改善浦东 新区大气污染状况提供依据。

Critical engagement,activist/academic subjectivities and organic agri-food research in Uganda

This paper provides a reflexive account of engagement in activist/academic organic agri-food research in Uganda. I argue that critical engagement across the third space – between and across activist and academic subjectivities – enables a re-thinking of the subjectivities of activist/academics and research participants and the place of research in social change and theory building. I demonstrate some of the multiple ways of enacting activism within the academy by reflecting on my critical engagement with the Katuulo Organic Pineapple Cooperative in Uganda, whose members grow certified organic pineapples for sale on the international market. While there is a growing interest in critical activist research, its agenda is also constrained by the corporatist turn in universities. As such, the subjectivities, methods and theory building of activist/academics in agri-food (and other) research represents part of the resistance to normalised ways of doing and being in contemporary neo-liberal universities.
