遥感监测技术在上海河道边坡水土流失状况监测中的应用

Application of Remote Sensing Monitoring Technology in Water and Soil Erosion Monitoring on Riverway Slope in Shanghai

上海市位于平原河网密布地区,为精准高效监测全域河湖边坡水土流失状况,采用遥感监测及无人机等现场实地调查手段相结合的方式,开展重点监测范围区内的河道边坡水土流失状况监测,共建立不同河道护坡类型解译判读标志9套,掌握了重点监测范围区内河道两岸护坡种类和护坡状态,为防治河道两岸水土流失提供科学依据。上海市河湖边坡堤岸坍塌、自然护坡所可能导致的水土流失量可以在此基础上做进一步探索和研究。基于此,文章针对遥感监测技术在上海河道边坡水土流失监测中的应用展开论述,以供参考。

Shanghai is located in a plain area with a dense river network.In order to accurately and efficiently monitor the water and soil erosion on river and lake slopes in the whole area,a combination of remote sensing monitoring,unmanned aerial vehicle and other on-site field investigation means is used to carry out the monitoring of water and soil erosion on riverway slopes in key monitoring areas,co-establish 9 sets of interpretation signs for different riverway slope protection types,grasp the types and status of slope protection on both sides of the riverway in key monitoring area,and provide a scientific basis for the prevention and control of water and soil erosion on both sides of the riverway.The amount of water and soil erosion caused by the collapse on river and lake slopes and natural slope protection in Shanghai can be further explored and studied.Based on this condition,this paper discusses the application of remote sensing monitoring technology in water and soil erosion monitoring on riverway slope in Shanghai,for reference.
