文摘内容 The natural hazard in mountainous regions where debris flow is the most active phenomenon has been put under a focal task of research and control in the Jiangjia Ravine.The previous efforts are mainly devoted to analysis of both findings in the field investigation and data from monitoring stations following the traditional way,ie.to spread the analysis over a whole area from one point.In order to inquire further into the causes and the consequences of debris flow,it is necessary to provide a much more comprehensive information of disastrous activity to combine correctly the image interpretation of airphotos taken in different periods with the on-the-spot investigation on the major districts of the study area.The information contented,which can be extracted from airphoto analysis to a great extent,depends upon the interpreters’professional knowledge and the technical instruments used by them.There is a presentation of some preliminary results and suggestions for improvement in the article.
