Artemisia ordosica is the pioneer plant in the cross areas of windwater erosion in Loess Plateau in China, which plays an important role in the stability of the ecosystems in the regions. We chose the shrub patches as the research objects. Based on the plot investigations in the cross areas of windwater erosion, the static life table was established, survival curves and the function curves derived from the survival analysis were also constructed to evaluate the A. ordosica shrub patch population characteristics. The A. ordosica population dynamics were predicted by a timesequence model. The results showed that: (1) the age structure of the A. ordosica shrub patch was a pyramid, but there were fewer individuals in classes I and Ⅱ than in class Ⅲ; (2) The number dynamics index (V′_pi) was close to zero, so the A. ordosica shrub patches were sensitive to environment disturbances; (3) The survival curve of the A. ordosica shrub patch appeared to approach the DeeveyⅡ type, which indicated that the mortality rate in different size classes was similar; (4) The survival analysis and the timesequence model demonstrated that the lack of young individuals could be the major cause for the decrease of middle size class shrub patches. Therefore, the research suggested that the A. ordosica shrub patch, in Loess Plateau in China, could grow, renew, and adapt well in the cross areas of windwater erosion climate environment, and the population was in stable increasing the situation, which created the water and nutrient condition for the settle and recover of other plants.
