城市里的"声音景观"变化，为什么也反映生态健康？
Why does a city's changing "soundscape" also reflect ecological health?
蛙鸣、鸟叫、虫声是生物活跃的信号，噪声盖过它们说明生境受压；用录音监测"声音多样性"，能不惊扰动物就估出城市的生物多样性。
Frog, bird and insect sounds signal life; noise drowning them shows stressed habitat. Recording "sound diversity" estimates urban biodiversity without disturbing animals.

城市"热岛"为什么往往在夜里更明显？
Why is the urban "heat island" often strongest at night?
混凝土和沥青白天吸热、夜里慢慢放出，而乡村植被和土壤散热快；到了晚上城市比郊外"余温"更高，温差反而拉大。
Concrete and asphalt store daytime heat and release it at night, while rural vegetation and soil cool fast; after dark the city's "leftover warmth" makes the gap with suburbs wider.

城市高楼间，为什么红隼这类猛禽也能活下来？
Why can raptors like kestrels survive among city high-rises?
楼缝像峭壁、绿地和鸽群提供猎物，城市反而给它们"人造悬崖"和稳定食源；只要少打扰，猛禽也能在人底下安家。
Building gaps mimic cliffs, and greens and pigeons supply prey, so the city offers "artificial cliffs" and steady food; with little disturbance, raptors nest right above us.

屋顶绿化为什么能一边降温、一边帮城市"吞"雨水？
Why can green roofs both cool and help the city "swallow" rainwater?
植被和土层遮挡日晒、蒸发吸热，给顶层降温；同时像海绵蓄住一部分雨水，减轻下水道压力，是"一绿多用"的小基建。
Vegetation and soil block sun and cool by evaporation, lowering top-floor heat; they also sponge up rain, easing sewers—a small "one-green-many-uses" infrastructure.
