英文文献：Impact of Environmental Policies on the Adoption of Animal Waste Management Practices in the Chesapeake Bay Watershed-环境政策对采用切萨皮克湾流域动物粪便管理做法的影响我们利用ERS-NASS ARMS调查的数据，比较流域内和流域外家禽和牲畜养殖场最佳管理做法的使用情况

英文文献摘要：
We use data from the ERS-NASS ARMS surveys to compare the use of best management practices on poultry and livestock farms inside the watershed and outside the watershed. Animal operations within the Chesapeake Bay States were found to be adopting some important manure management practices at a greater rate than operations outside the watershed. Adoption was taking place before the implementation of the TMDL, indicating that farmers may have been acting in response to building public pressure to reduce pollution.
研究发现，切萨皮克湾州内的动物作业采用了一些重要的肥料管理方法，其比率高于流域以外的作业。在实施千年发展目标之前就已通过，这表明农民可能是在响应公众减少污染的压力。
