| Abstract:History temperature and relative humidity of 12 constantly controlled temperature and humidity storerooms and 45 lightly controlled temperature and humidity storerooms in the North China Plain were analyzed， and the corresponding life expectancy and mechanical damage risk of paper cultural relics conserved in above-mentioned condition were calculated. It was found that allowing temperature in constantly controlled temperature and humidity storerooms had seasonal fluctuations that adapted to the changes of ambient climate within the recommended range， which could improve the energy economy and stability of temperature and relative humidity in the conservation environment， while didn’t affect the safety of paper cultural relics. Most of the year， the history temperature and relative humidity of the lightly controlled conservation environment in the North China could ensure the safety of paper cultural relics. Conserve paper cultural relics 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， increased the temperature setpoint. When temperature reached the upper limit of the allowed range， control temperature and relative humidity at the same time. It was a sustainable conservation strategy for year-round or seasonal cool/dry areas. |
