Abstract Wagner KJ. 2019. Preface: advances in hypolimnetic oxygenation. Lake Reserv Manage. 35:225–228. Hypolimnetic oxygenation systems (HOS, here taken to mean techniques that add oxygen to the bottom layer of a lake or reservoir without disrupting stratification) have been in use for over half a century. However, issues of theoretical understanding, equipment, implementation, monitoring, and cost have limited widespread application of what is a potentially very effective means of improving water quality. Advances of the last two decades have pushed HOS to the forefront of water supply management, with some application in recreational lakes as well. Key advances include demonstration of long-term improvement of water quality, including higher concentrations of oxygen and lower concentrations of reduced compounds and algae, better predictability of results, including greater understanding of oxygen demand and its expression, and characterization of capital and operational costs, including likely changes over time as oxygen demand is satisfied. The application of additional management techniques in many cases limits our ability to ascribe all positive results to HOS alone, but the value of HOS as a lake management tool has been clearly demonstrated. More applications with careful monitoring and documentation of results are expected to advance this approach further.

前言:水下氧合研究进展

摘要瓦格纳 KJ。2019. 前言:水下氧合的进展。湖泊保护区管理。35:225-228。Hypolimnetic 氧合系统(HOS,这里指的是在不破坏分层的情况下向湖泊或水库的底层添加氧气的技术)已经使用了半个多世纪。然而,理论理解、设备、实施、监测和成本等问题限制了这种潜在的非常有效的水质改善手段的广泛应用。过去二十年的进步将居屋推向供水管理的前沿,在休闲湖泊中也有一些应用。主要进展包括证明水质的长期改善,包括更高浓度的氧气和更低浓度的还原化合物和藻类,更好的结果可预测性,包括更好地理解需氧量及其表达,以及资本和运营成本的特征,包括随着时间的推移可能会随着氧气需求得到满足而发生的变化。在许多情况下,额外管理技术的应用限制了我们将所有积极结果单独归因于居屋的能力,但居屋作为湖泊管理工具的价值已得到明确证明。预计更多具有仔细监测和结果记录的应用程序将进一步推进这种方法。在许多情况下,额外管理技术的应用限制了我们将所有积极结果单独归因于居屋的能力,但居屋作为湖泊管理工具的价值已得到明确证明。更多具有仔细监测和结果记录的应用程序有望进一步推进这种方法。在许多情况下,额外管理技术的应用限制了我们将所有积极结果单独归因于居屋的能力,但居屋作为湖泊管理工具的价值已得到明确证明。更多具有仔细监测和结果记录的应用程序有望进一步推进这种方法。
