东北地区的冬季保护地设施的密闭性能较好，蒸发出来的水分散发不出去，造成保护地内的空气湿度偏高，相对湿度经常在８０％－９０％，甚至在夜间达到１００％，常是饱和状态，所以保护地的环境湿度比较特殊。 一、保护地的湿度条件和特点 １、密封性能较好的设施空气相对湿度 The winter protected areas in Northeast China have better sealing performance and can not get out of the evaporated water. As a result, the air humidity in the protected areas is high, and the relative humidity is often 80% -90%, even reaching 100% at night, often saturated State, so the protection of the environment humidity is rather special. First, the protection of wetlands conditions and characteristics 1, better sealing performance of air relative humidity
