Assessment of the Effects of Fencing Enclosure on Soil Quality Based on Minimum Data Set in Biru County of the Qinghai–Tibet Plateau, China

Fencing enclosures play an important role in improving ecological quality. There is a direct impact of implementing fencing on the change soil The quality index was used to examine effects for different years (7 and 11 years) Biru County Qinghai–Tibet Plateau, China. enclosure significantly increased water content, non-capillary porosity, organic matter, total nitrogen, phosphorus, alkali-hydrolyzable decreased bulk density. gradually improved as time length increased, probably due increase vegetation coverage biomass under enclosure. minimum data set composed capillary potassium, porosity. correlated with could replace evaluation project area. In summary, our study reflects that improve quality, implementation will effectively curb land degradation
