- Abstract:
-
Fenced grassland, open grazing grassland and tourism areas in Xilamuren Grassland were surveyed combining with the Fifth Desertification and Desertification Monitoring Implementation Details of Inner Mongolia Autonomous Region, grassland degradation was diagnosed and evaluated according to indicators such as vegetation cover and biomass. Based on this, characterization of surface coarse particles of different degrees of degradation was studied. The results showed that the fenced grassland was mainly mild degraded; open grazing grasslands were mainly moderately degraded, but the top of the hill was severely degraded. Degradation degree at tourism areas was the most serious degraded. Volume percentage of non-erodible particles(> 0.84 mm) could be used as an appropriate discrimination standard to evaluate the grassland degradation degree, it is severe degradation when its content is 82.22%~89.04%, moderately degraded with its content of 74.01%~79.53%, mild degraded with its content of 56.05%~66.11%. The index may intuitively and real-time reflect the degradation situations of grassland, and it is also a simple, rapid diagnostic application to the practice.
