| 摘 要： | 利用沼泽湿地及其周围旱田对比观测的方法,对沼泽湿地的局地小气候效应进行了研究。结果表明:与周围旱田相比,沼泽湿地近地层(0.5—5.0m)气温低,湿度大,具有显著的冷湿岛效应,且不同高度冷湿效应表现不同,越靠近地面,冷湿效应越明显。6—9月的野外试验结果表明,沼泽湿地的冷湿岛效应在7、8月比较明显;比较沼泽湿地和旱田温度、湿度的日变化发现,沼泽湿地在12:00—14:00的日间午后时段呈现出较明显的冷湿岛效应。

| Abstract: | By observing marsh wetlands and their surrounding dry farmlands for comparison,effect of marsh wetlands on localized micro-climate is analyzed.Results show that marsh wetlands,compared with their surrounding dryland,are lower in temperature but high in humidity in the surface layer,displaying a significant cold-humidity island effect,which varies with elevation.The closer to the land surface,the more significant the effect.The field observation from June to September found that the cold-humidity island effe... |
