摘要
土壤的土层厚度是计算上壤抗蚀年限重要依据，应用已有的土壤调查成果将全省的土层厚度进行分级、统计，再用遥感普查中的侵蚀模数计算出不同7层厚度之区域的抗蚀年限，为土壤侵蚀的预测预报提供重要的基础数据。
The thickness of soil layer is an important basis for calculating its year limitation for resistant erosion. The thickness of soil storey for whole province is classed and c0unted by using the soil survey results had been done. Then, the year limitation for soil resistant erosion of different thickness of seven soil layers have been calculated by using soil eroded patterns of telemetering survey,these supply for the important information in the soil eroded forecast.
