In order to evaluate the radiation shielding efficiency on proton displacement damage for the CCDs that will be boarded space solar telescope project (SST) of China, based on the work of Janesick et. al's, a method is developed to get the stable defects produced by the incident protons. Then the proton caused degradation of the CCD specifications of charge transfer efficiency (CTE) and bulk dark current generation is calculated for SST after its 3-years-long mission on orbit and a 3mm thick aluminum shield is suggested for the CCDs of the mission. The method is a new attempt to predict the displacement-induced CTI and dark current together.
