Abstract: The effects of different types of Chinese fir stand, including those with different rounds of continuous cropping, different ages and different site indexes in northern Fujian province were studied by means of ecological sequential comparison . The results revealed that physical properties of soil were greatly influenced by the continuous cropping of Chinese fir. Especially in the mid age stands, the soil volume weight increased, capillary, non capillary and total porosity of soil under the second and the third plantings decreased, compared with the first one. Soil permeability also became worse. For the young plantation, due to the influences of site preparation and tending, the effects of continuous cropping on soil physical properties were not as clear as those in the mid age stands.
