摘要:本文分析了华北平原12间恒温恒湿库房和45间温湿度轻控制库房的历史温湿度，并计算了纸质文物在上述历史温湿度下保存的预期寿命和机械损伤风险。研究发现，恒温恒湿控制时允许保存温度在推荐范围内随外界气候变化存在一定的季节波动，能够在不影响纸质文物安全的情况下提高温湿度控制的能源经济性和保存环境的温湿度稳定性。在华北平原，大部分时段轻控制温湿度能保证纸质文物安全。凉爽/干燥季节低温保存，当大气湿度升高使得保存湿度接近允许上限时提高温度设定值，当保存温度达到允许上限后再同时控制温湿度，是全年或季节性凉爽/干燥地区的一种可持续性纸质文物保存温湿度调控策略。

Abstract:The history temperature and relative humidity of 12 constantly controlled conservation environment and 45 less controlled conservation environment in the North China Plain were analyzed, and the corresponding life expectancy and mechanical damage risk of paper cultural property conserved in above-mentioned condition were calculated. It was found that allowing temperature in constantly controlled conservation environment have seasonal fluctuations that adapt to the changes of ambient climate within the recommended range, which can improve the energy economy and stability of temperature and relative humidity in the conservation environment, while didn’t affect the safety of paper cultural property. Most of the year, the history temperature and relative humidity of the less controlled conservation environment in the North China can ensure the safety of paper cultural property. Conserve paper cultural property at lower temperature in cool/dry season. When the relative humidity of conservation environment reached the upper limit of the allowed range as the humidity of atmosphere rises, increase the temperature setpoint. When temperature reached the upper limit of the allowed range, control temperature and relative humidity at the same time. It is a sustainable conservation strategy for year-round or seasonal cool/dry areas. Key words: paper cultural property; conservation environment; temperature; relative humidity; sustainability
