摘要:

在详细论述土壤水资源概念发展和土壤水分植被承载力研究尺度的基础上,介绍土壤水分植被承载力量化模型,包括经典的承载力模型、种群增长通用模型、密度-土壤水分模型和基于物理过程的土壤水分植被承载力模型,述评土壤水分植被承载力研究现状,提出今后应在完善土壤水分植被承载力理论的同时,加强水资源紧缺地区土壤水分与植物生长的野外长期定位研究,从不同时空尺度确定不同植物群落的土壤水分承载力。

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
