The Study of the Federal Regulation of Pesticides and its Experiences for China [PDF]
, 2016 农药在帮助人们远离疾病、农作物病虫害、提高作物产量等方面发挥了重要作用，极大促进了现代农业的发展。美国20世纪六七十年代开展的环境保护运动让人们更清楚地认识到农药在给生产生活带来便利的同时也可能会危害人类健康、威胁自然生态的平衡。 中美两国都是农药生产和使用大国，美国《联邦杀虫剂、杀菌剂及灭鼠剂法》的出台，明确了以国家环保局为主管，以农药登记为核心的管理体系，有效控制了农药污染，在农药管理方面走在了世界前列。中国的农药管理起步较晚但发展迅速，已经建立起初步的管理架构，但具体制度设计上仍有不足 ...

Study on Remote Monitoring System for Fish Activity and Water Quality Environment in Offshore Fish Cage [PDF]
, 2016 在全球海洋渔业资源日益衰减的今天，深水网箱以其抗风浪、耐海流能力强、养殖容量大、高产高效、环保等优势成为现代耕海牧渔的发展方向。深水网箱养殖过程中，由于网箱离岸远，范围广，水体浑浊，不容易观察鱼群活动状态，同时也往往难以把握合适的投饲量，投饵过少将影响鱼类生长健康，过多则增大养殖饲料成本，同时剩余饵料又会污染环境。为了进行鱼群状态监测和避免饲养投喂的随意性和盲目性，急需加强深水网箱鱼群状态与水质环境监测，为正确判断鱼群食欲、科学进行投饲提供重要参考依据。本文根据深水网箱养殖环境的特殊要求 ...
