Agro-environment of the west of Jilin province is deteriorating under the impact of natural and human factors, which is directly presented by land saline-alkalization, grassland degeneration and land desertification.

This paper studied the prevention and control of grassland degeneration.

he paper was reported to cause the reason of grassland degeneration, and approach the problems of grassland management, conservation, rational use, and development.

The quadrat data from 1983 to 1994 were used to statistically analyze the changes in diversity and the main plant populations on degenerated steppe after light harrow for restoration.

Prediction of grassland degradation in Xilinhaote of Inner Mongolia based on Markov process model;

The Remote Sensing Monitoring of Grassland Degradation and Climate Causes in Hulun Buir Grassland;

Study on the Relation of Soil Thickness Spatial Distribution and Grassland Degradation Based on 3S

Technologies to monitor the rodent in the degraded grassland in "Three-River Headwaters" region;

Plant biodiversity of Aretemisia frigida communities on degraded grasslands under different grazing intensities after thirteen-year enclosure;

Restoration dynamics of degraded grasslands in the typical steppe zone of inner Mongolia;

Natural and man-made factors affecting grassland degradation were analyzed and several measures were presented to control grassland deterioration,providing a exploration for eco-protection in water head region.
