摘要:
主要对普定典型喀斯特石漠化地区土壤含水量变化的影响因素进行了研究和探讨，简要分析了气象、石漠化、坡度、植被、土壤性状等因素对土壤水分的影响。研究结果表明：降水量是土壤含水量的主要控制因子；土壤含水率与湿度呈正相关，与气温呈负相关；不同发育程度的石漠化样地的土壤含水量大小顺序依次为：潜在石漠化＞轻度石漠化＞中度石漠化；植被覆盖度与土壤含水量呈正相关；土壤含水量随坡度的增加而减小；土壤含水率与土壤厚度呈正相关；土壤质地对土壤水分入渗能力有一定的影响，但土壤化学性质对土壤含水量影响较小。
Abstract:
The article studies and discusses influencing factors about variation of soil water content in Puding typical karst rocky desertification region. Changes of soil moisture affected by weather rocky desertification slope vegetation soil properties and other factors is analyzed in brief. Research shows: precipitation is the main controlling factor of soil moisture; soil moisture content and humidity were positively correlated, meanwhile negatively correlated with air temperature. Different developmental levels of rocky desertification plots sort order of the size of the soil moisture: Potential rocky desertification>mild rocky desertification>moderately rocky desertification. Vegetation coverage was positively correlated with soil moisture content. Soil moisture decreases with the slope increasing. Soil moisture content was positively correlated with soil thickness. Soil texture produces certain influence on moisture infiltration into soils, while the soil chemical properties have little influence on the soil water content.
