In dry valleys in southwestern China, soil organic carbon (SOC) storage is very sensitive due to changes in land use. Characterizing SOC content variations is key to improving SOC sequestration and future land management. This study evaluated land-use changes, especially reforestation, and the effects on SOC variability in a small dry watershed in the Minjiang river valley. Multivariate methods indicate...
From a spatial view, the rural-urban fringe zones are rapidly change areas near big cities. It is evident that the road construction and improvement played an important role in these processes. Quantifying the landscape change of main road on land use is important to elucidate effects in future. We chose an expressway near Beijing as a case, calculated and compared the land use change in 1991 and...
A study was initiated in a small semi-arid catchment with reforestation history to elucidate the soil change. Results showed that land use pattern was closely related with terrain conditions and human disturbance levels. Soil properties under four typical human-disturbed land use types (orchard, shrub, cropland and reforested land) were compared. Significant differences were found for total nitrogen...
