Gongye shui chuli, 2002 采用系统论的基本原理,分析了水的自然循环和社会循环的系统特性;认为水的自然循环是具有自组织结构的非平衡开放系统,水的社会循环是具有人工组织结构特性的非平衡开放系统。探讨了水工业体系与水循环系统的统一性。根据系统结构决定系统功能的原理,提出了建立水工业体系应以整个水的社会循环作为对象、以系统科学理论作为认识论和方法论、优先组建系统运作三要素等建议。

Gongye shui chuli, 2008 对污水厂出水经过深度处理后回用到循环水系统作为补充水，且循环水排污又回流到污水厂的系统，将产生内循环浓缩，使TDS和COD升高，由于循环系统补充水有TDS上限值，污水循环回用比也存在上限值。提出了污水循环回用比和回用后污水厂出水COD的确定方法。

New Phytologist, Volume 247, Issue 6, Page 2616-2629, September 2025.Summary Seagrasses are important contributors to environmental nutrient cycling in marine ecosystems and can improve water quality by absorbing excess nitrogen (N). However, these ecosystems are vulnerable to human‐mediated pressures, including marine heatwaves (MHWs), particularly those of longer duration. We performed an experiment simulating a 30‐d,
