Wind with sand is very great in west region of Jilin province. About 444

000 hectares of the wind erosion areas in 12 major counties and cities of the region have been controlled through hard efforts for many years since liberation

which is 82% of the total original wind erosion areas. This generates an important effect on lightening wind and sand harm

improving ecological environment and raising agricultural production level. It is unfortunate for the destruction from the 3-year-long economic difficulty

the influence of the "left" mistakes for long time and the decade of domestic turmoil disturbance to have enabled the wind erosion areas increasing greatly from 543

000 hectares just after liberation to 1.4 million hectares in recent years. Now there are 1.2 million hectares of desert and desert-blighted land to reform besides 220

000 hectares with serious wind erosion

having not tillaged for two years. Most part of the wind erosion area is with the flowing dunes

which is pouring into villages and small towns in 20m per year. Many farmers' yards have been piled up 1 metre high with sand

their doors buried. Because of the shortage of the "Three Materials"

the local residents still have a poor life

The main control measures suggested are as follows: 1

putting the land to rational use

changing the tillage system from extensive cultivation and poor harvest to deep ploughing and intensive cultivation; 2

planting trees and grasses substantially

developing the rural energy resources actively

controlling the wind erosion completely to improve the ecological environment effectively; 3

popularizing the way of the household contract control

implementing the concerned policies seriously

increasing the profits of the controlling and speeding up the harnessing.
