| Abstract: | The composition of a soil pore space is the objective reflection of pedon structure. Its total pore space increases with the decrease of its dispersed particles or the increase of aggregate particle; Space occupied by wilting water and capillary space increase with the decrease of particles; Aeration space increases with the increase of particles. Accordins to the difference of mechanical compositions and the composition of pore spaces in soil, We can distinguish the different types of pedon structure. |
