明尼苏达州农业景观中一个浅湖的恢复——一种理解变化的跨学科方法

【摘要】张建军，张建军，张建军，等。明尼苏达州农业景观中一个浅湖的恢复——一个跨学科的改变方法。湖泊保护区管理。XX: XXX-XXX。本研究以明尼苏达州绍卡坦湖为例，揭示了长期气候、水文、水化学和大型植物数据如何解释和预测浅湖相移。经过几十年的农业景观养分负荷，湖泊和流域管理工作成功地将夏季平均总磷和叶绿素a浓度降低到符合北部冰川平原生态区浅水湖泊专门设定的标准(分别为0.09 mg/L和0.03 mg/L)。该湖从浑浊的、浮游植物为主的阶段(大型植物的发生率<20%)“翻转”到清澈的、大型植物为主的阶段(年平均发生率为90%)，明尼苏达州污染控制机构将其从该州的受损水域名单中删除。地下水和湖泊水质成对调查对于了解降水增加如何影响湖泊水质，地下水和地表水在该系统中的关系，以及氯化物和磷等化合物如何通过流域运输至关重要。整个湖的大型植物的出现已经持续了至少7年。虽然大量的大型植物生长有助于保持清澈的水状态，但它也可能造成休闲划船的问题。当湖泊使用者权衡这两个阶段的娱乐和审美差异时，湖泊管理人员质疑湖泊将在目前的清澈阶段保持多久。关键词:氯化物地下水长期监测大型植物监测水体营养损害浅湖管理致谢感谢MDNR和MPCA的众多工作人员进行了实地调查并协助进行了数据管理。我们感谢他们和我们各机构的领导认识到长期、多学科监测的价值。J. Lauer, S. Kloiber和E. Smith提供了对本文进行改进的评论和有益的意见。披露声明作者未报告潜在的利益冲突。

期刊介绍： Lake and Reservoir Management (LRM) publishes original, previously unpublished studies relevant to lake and reservoir management. Papers address the management of lakes and reservoirs, their watersheds and tributaries, along with the limnology and ecology needed for sound management of these systems. Case studies that advance the science of lake management or confirm important management concepts are appropriate as long as there is clearly described management significance. Papers on economic, social, regulatory and policy aspects of lake management are also welcome with appropriate supporting data and management implications. Literature syntheses and papers developing a conceptual foundation of lake and watershed ecology will be considered for publication, but there needs to be clear emphasis on management implications. Modeling papers will be considered where the model is properly verified but it is also highly preferable that management based on the model has been taken and results have been documented. Application of known models to yet another system without a clear advance in resultant management are unlikely to be accepted. Shorter notes that convey important early results of long-term studies or provide data relating to causative agents or management approaches that warrant further study are acceptable even if the story is not yet complete. All submissions are subject to peer review to assure relevance and reliability for management application.
