[Objective] The objective of this study is to clarify the growth rule (i.e. maximum growth potential) and regenerating process of Caragana korshinskii and in order to provide basis for the rational utilization of C. korshinskii. [Methods] We evaluated the 24-years in-situ observation records of growth process of C. korshinskii in the semi-arid regions of Ningxia Hui Autonomous region using quantitative statistical analysis. [Results] (1) The growth of C. korshinskii was mainly impacted by water

especially the soil moisture. The shrubbery at the lower slope always grew better than the ones at the middle and upper slope. Soil water contents at soil layer of 0 m to 8 m in the middle or upper slope significantly influenced the growth of C. korshinskii. During the middle period of C. korshinskii growth

branching numbers

ground diameter and the aboveground biomass varied significantly among different parts of slopes. However

the senescence of plants was severe at the later stage since the physiological and ecological functions of C. korshinskii degraded year by year. (2) Except its biological characters

environmental factors and growth indexes also impacted the growth of C. korshinskii. The biomass at the lower slope was influenced by the numbers of branching. The biomass at the middle slope was impacted by the branching number

ground diameter and the plant height

while ground diameter

plant height and crown width controlled the shrub biomass at the upper slope. (3) All growth indexes were significantly positively related with the cumulative temperature and evaporation. The former was important factor at all parts of slopes. [Conclusion] Hydrothermal conditions are the main limitation factors for the growth of C. korshinskii.
