Abstract:

In this paper, development of concept of soil water resources and research scale of soil water carrying capacity for vegetation were discussed in detail. We introduced models of quanlifying soil water carrying capacity for vegetation, including classic mode of carrying capacity, general model of population growth, density and soil water model and physically based model and soil water carrying capacity for vegetation, and reviewed the present status of study on the soil water carrying capacity. It is suggested that we should further improve the theory system on soil water carrying capacity for vegetation and quantify the value of soil water carrying capacity at different spatial and temporal scales for different plant communinity in water limited region, and strengthen a long-term location investigation of relationships between pland growth and soil water in the future.

Key words: water-limited region, soil water resources, plant growth, scale, soil water carrying capacity for vegetation, quantifying model
