The tempo-spatial scanning of Load /Unload Response Ratio in the Xinjiang region was conducted，and the evolutionary characteristics of tempo-spatial of LURR abnormal regions in 2000 ～ 2012，and the statistics of the quantitative relations between earthquakes and tempo-spatial evolution of LURR were researched on the basis of integral of LURR． The scanning results during 2011 ～ 2012 and the MS≥5． 0 earthquakes happened in the second year were compared． The result shows that most of moderately strong earthquakes happened in the predicted region preceding year． The variation of integral of LURR against time for four earthquakes with MS6． 0 in the Xinjiang region in 2011 ～ 2012 has been calculated respectively． The result shows that integral of LURR will reach peak value several months before the earthquakes，and earthquakes will happen during the course of high value fluctuation or fall back．
