Shuitu Baochi Xuebao, 2003 三峡库区生态环境的质量直接关系到三峡工程的长治久安,三峡库区属我国典型的内陆腹地农业经济类型区,生态农业的发展是该区农业现代化的必然选择。研究通过2000～2001年于三峡库区的开县进行不同生态农业模式效益的田间对比试验,结果分析表明,果牧结合(果-草-羊)的生态农业模式与单纯果园、果-菜结合等传统的农业模式相比,不但具有显著的经济效益、较好的社会效益,而且能显著改善土壤物理性状,增强土壤保蓄水力,提高土壤肥力;同时能有效地减少果园病虫发生,减少田间杂草的多样性,从而维护农业生态环境。

Study on disinfection and sterilization of high algae-laden water with Hydroxyl radicals [PDF]
, 2016 消毒灭菌是饮用水处理工艺中的重要组成部分。而地表水富营养化现象日益加剧，导致水源地高藻频发，增加了饮用水常规氯消毒处理工艺的负担，严重威胁城市供水卫生安全。如何平衡饮用水微生物安全性与化学安全性，成为当前高藻饮用水消毒技术研究的重要内容。本文依托国家科技支撑计划项目“高藻水源地供水卫生保障羟基自由基氧化技术研发与示范”(NO.2013BAC06B00)，针对厦门市重要水源地九龙江北溪流域水体，通过大气压强电离放电规模制备羟基自由基(•OH)，建立了高藻饮用水•OH消毒灭菌处理工艺，
