本文在利用遥感技术对河北省山区以泥石流为主的地质灾害进行详细研究的基础上，采用多因素评判法，对河北省山区地质灾害发育程度进行了分区划分，并圈定了需要重点监测和防御的灾害区段。该成果为河北省山区的地质灾害防治、减灾、救灾等工作提供了科学依据，具有重要的实用价值。 Based on the detailed study of debris flow-dominated geological disasters in mountainous areas of Hebei Province using remote sensing technology, this paper uses the multi-factor evaluation method to divide the development degree of geological disasters in mountainous areas of Hebei Province and delineates the need for key monitoring and prevention Disaster zone. The results provide a scientific basis for the prevention and control of geological disasters, disaster reduction and disaster relief in mountainous areas of Hebei Province and have important practical value.
