New CCD photometric observations for asteroid(1028)Lydina,carried out with the 1-m and 2.4-m telescopes at Yunnan Observatory from 2011 December 19 to 2012 February 3,are presented.Using the new light curves,the rotation period of 11.680±0.001 hours is derived with the Phase Dispersion Minimization(PDM) method.In addition,using the Amplitude-Aspect method,the elementary results of the pole orientation of asteroid(1028)Lydina are obtained:λp=111°+4°-4°,βp=31°+4°-5°. Meanwhile,the axial ratios of the tri-axial ellipsoid are estimated:a/b=1.77+0.10 -0.08 and b/c=1.17+0.07 -0.09 .
