试卷: LEED v4 GA模拟题A卷[查看] Which of the following can happen as a result of increased rainwater runoff? A: Eutrophication B: Increased heat islands C: Decreased energy performance D: Increased potable water use 参考答案: A
本题解释: A:Eutrophication is the ecosystem response to the addition of artificial or natural substances, such as nitrates and phosphates from fertilizers or sewage, to an aquatic system.
Additional hardscapes can contribute to eutrophication and harm aquatic ecosystems and species.
Eutrophication is the process by which a body of water acquires a high concentration of nutrients, especially phosphates and nitrates. These typically promote excessive growth of algae. As the algae die and decompose, high levels of organic matter and the decomposing organisms deplete the water of available oxygen, causing the death of other organisms, such as fish. Eutrophication is a natural, slow-aging process for a water body, but human activity greatly speeds up the process.
