	<span style=\"font-size:10pt;\"><span style=\"font-size:12px;\">The paper put forward a new method of loess microstructure analysis to determine whether the loess seismic subsidence deformation to be strong or weak. In the dryer and colder climatic conditions of northwest of China, the loess microstructure formed in certain conditions changed by the special climate and desert surroundings. According to its chemical element ratio (such as Si/Al, Ca/Fe, K/Al, Ca/Mg) and seismic s</span><span style=\"font-size:12px;\">ubsidence, we could divide them into four kinds</span><span style=\"font-size:12px;\"> of microstructures: strong shear deformation microstructure(I); strong compaction deforma</span><span style=\"font-size:12px;\">tion microstructure(II); the medium seismic</span><span style=\"font-size:12px;\"> sub</span><span style=\"font-size:12px;\">sidence microstructure(III); the low seismic</span><span style=\"font-size:12px;\"> sub</span><span style=\"font-size:12px;\">sidence microstructure(IV).
