Abstract
The major harness area in the middle and lower reaches of JialingRiver is related to 48 counties and cities
covering an area of 6.97 millionha. with serious soil and water loss
being 63% of the local area
theannual average amount of soil loss is 321 million ton. The area is lookedwith naked rock and red soil everywhere
and is thought as the typicalone in vicious cycle of ecological environment. A harness plan was advanced in July
1988
the leading idea
planning principle
target
rationality and availability of the benefit criterion as well as the reliability toarrange each measures and the notabillty to increase yield and incomewere discussed.
which heightens the believe and determination to harness.
