Abstract

It is known that the soil loss area of Jiangsu Province is about 4

395.5km~2 from the interpretation by remote sensing and the measurement byphotoelectric scanner

in which the area of slight to light erosion is3

674.4km~2

in moderate and strong erosion is 578.6km~2 and 142.5km~2 respectively

being amounted to 83.6%

13.2% and 3.2% of the total respectively.From the point of risk extent

the area in no risk is 71.5%

in somerisk 14%and much risk 14.5% of the total. The control measures are toimprove the engineering systems of water conservancy and soil and waterconservation at first

to plant trees

brushes and grasses widely and topopularize the system of no till.
