Research on current situation and countermeasures of comprehensive soil and water loss control in Hubei Province
Hubei Province has achieved remarkable results in soil erosion prevention and control,but the current effectiveness of soil erosion prevention and control is still unstable,and the task of prevention and control is still heavy.The establishment of a mo-nitoring and evaluation mechanism for the implementation of the plan,grasping the full-caliber soil and water erosion control,and tracking the implementation of the plan are conducive to the practical enhancement of the regional soil and water erosion control benefits,and the solid improvement of the regional soil and water erosion situation.We collected and collated the implementation status of full-caliber soil and water erosion control in three-level soil and water conservation functional zones in eight typical counties,Hubei Province,as well as various types of project patches,completion and acceptance maps,and satellite images of the assessment year,etc.In combination with the analysis of GF-1 satellite remote sensing imagery and the vectorized treatment pat-ches on site by unmanned aerial photogrammetry,we completed the informatization and calibration work of the patches on site.This work has understood the implementation status of the full-caliber new soil erosion control tasks in 2020 in scales of sector,project,measure,and spot.It is found that the accuracy rate of the coordinates of the spots of full-caliber soil erosion control measures in Hubei Province is 96.13%,the effective rate of the spots is 93.22%,and the rate of completion of the spots is 97.37%.However,some practical difficulties still exist:there is a certain lag in the progress of some of the projects,the configura-tion of supporting facilities in the field is not too perfect,and the risk of man-made disturbances remain high,etc.Accordingly,countermeasures and suggestions were put forward to strengthen the target responsibility assessment,improve the supervision,in-spection,and supervision mechanism,and promote the coordination of prevention and control work,to provide a decision-making basis for soil erosion control in Hubei Province to meet the objectives and tasks set out in the National soil and water conservation plan(2015～2030).
