Though the wilting coefficient of soil tend to increase as water retaining agents increased, the amplitude was low, so the soil availablewatercapacity augmented obviously.
土壤凋萎系数虽有增大趋势，但增幅很小，土壤有效水容量明显增大。

Soil availablewatercapacity (AWC) plays an important role in the evaluation of drought resistance of soil, planning and managing water resources and conducting irrigation.
土壤有效含水量（AWC）是评价土壤抗旱性、水资源规划和管理以及指导灌溉的重要依据。

The effects of forest fires on soil separate coefficients, porosity, saturated water-retaining capacity, available Mg, fine root significantly varied between the fire intensity.
