| 摘 要： | 基于西安市三条道路黄土路堑边坡植被防护调查和室内土壤含水率测试结果,研究分析了坡位、坡度、坡向、植被类型和植被防护模式对黄土路堑边坡土壤水分空间分布特征的影响。结果显示,中坡位土壤含水率大于下坡位,下坡位大于上坡位;高坡级边坡土壤含水率大于低坡级;小坡度边坡土壤含水率大于大坡度;阴坡土壤含水率大于阳坡;贴地植被土壤含水率大于直立植被土壤含水率;草灌结合模式的边坡土壤含水率小于灌木单一模式,但前者的生长状况优于后者。

| Abstract: | Based on field investigation carried on three loess high-cutting slopes in Xi'an City and combining indoor moisture content test, the influence of the slope position, slope gradient, slope direction, vegetation type and vegetation protection mode of the loess cutting slope on spatial characteristics of soil moisture was studied. The result showed that soil moisture content was greater in middle slope site than that in downhill, in downhill was greater than that in uphill; in high slope level was greater than that in low slope level; in low gradient slope was greater than that in the high gradient slope; in cloudy slope was greater than that in sunny slope; in ground vegetation was greater than that in the vertical vegetation; in the slope with grass and shrub combination mode was smaller than that in the single shrubs mode, but the growth of the former was better than the latter. |
