气候特征对西北半干旱半湿润地区土遗址掏蚀病害发育影响研究

he growth and development of basal sapping diseases is one of the most common, most typical and harmful processes on safety occurrence of earthen sites controlled by climatic factors. Based on the investigation and statistics of basal sapping diseases, combing climatic factors, we qualitatively analyzed the influence of climatic factors on the development degree of basal sapping diseases. The analysis results showed that parameters closely related to the growth and development of basal sapping diseases such as drought index is very sensitive to the amount of basal sapping. The drought index can be used as a good comprehensive index of evaluating the effect of climatic factors on basal sapping diseases. The research can provide some helpful references for studying on development mechanism and effective prevention of basal sapping diseases.
