| Abstract: | The grassland monitoring data on North Slope of Qilian Mountains were used to analyze the grassland resources and their deterioration situation. The results showed that the total grassland area, usable grassland area, deteriorated grassland and the fresh grass yield were 4.33 ×106 hm2, 3.91×106 hm2, 3.32×106 hm2 and 5.651×109 kg in 2008 respectively. The areas of desertification grassland, pest damaged grassland, rodent damaged grassland, poisonous grasses//weeds type grassland and salinized grassland were 2.722×105 hm2, 5.838×105 hm2, 4.93×105 hm2, 4.25×105 hm2 and 5.67×104 hm2 respectively. Accordingly, the proportions of the different deteriorated grassland area to the total grassland area in research region were 6.29%, 13.55%, 11.44%, 9.86%, and 1.32%. |
