Development Of The Dynamic Monitoring System For Soil Erosion And Applying Research Of The System In The Landing Covering System

3S"technology provide the dynamic monitoring system for soil erosion with a favorable developing circumstance and new means of technology . It be used to father soil erosion that the measure of applying vegetation . The dynamic monitoring system of soil erosion supply technical support for estimating the effect of fathering soil erosion by vegetation .Adopting the quantificational method of remote sensing .applying to the monitoring model which is A-fRKSLCP , after calculating the six maps of gene by seeding the information that was make up of remote sensing and non_remote sensing , it can gain the actualitial maps of soil erosion in the little valley that locate on the upriver of the longchuan river ,which is the branch of the jinsha river in 1998 and in 1999 by exerting the program of multiplication .It can gain the total quantity of soil erosion that happen in each pixel inside the little valley and that the total quantity of soil erosion in 1998 is 4840069.16t and the quantity in 1999 is 8690182.6t. This methcd possess the character of speediness, nicety and economy .Adopting the dynamic monitoring model which was built , it can gain the total quantity of soil erosion controlling in the woodland and grassland by contrast to bare land inside the little valley under the landing vegetation covering system was 1726926.32t . after discussing the best style of vegetation controlling soil erosion , ndnpiing (he monitoring model , basing on Ihc dala in 1998, designing the landing vegetation covering system ,it can gain the gross quantity of controlling soil erosion is 428221.44t after all plowland in the little valley that its slope is exceed to 25" are changed into woodland all wasteland are changed into woodland . then the total quantity of soil erosion are convert into 181339.57t.Adopting the dynamic monitoring system , i t can estimate well and truly the effect that the landing vegetation covering system can control soil erosion . so, this method can supply technical parameter for the department of water conservation and land management.
