Abstract  

The western Ordos Plateau of National Nature Reserve is a distribution center of many endangered shrub species such as Ammopiptanthus mongolicus. The effects of cutting on A. mongolicus were researched. After the cutting, the germination time was ahead about 7 d than the controlled plants. The biomass of the stubbles had completely restored in three years. Branch length of coppice shoot is 70.5 cm. Branch diameter of coppice shoot is 15.72 mm. Dynamic variations of the stubble population structure and soil structure revealed that cutting the cradling aging plants and deadwood could reduce the water consumption. Therefore the population structure between stable type and decline type with potential recovering capacity was formed, in which the ratio of young individual was higher than that of the decline type but lower than that of the stable type. It can improve population structure. The soil moisture in cut woodland is 0.57% higher than controlled plot.

Key words:  Ammopiptanthus mongolicus      cut      mass growth      population structure
