Effect of Land-use Types on Soil Organic Carbon and Paniculate Organic Carbon in Ecotones of Agriculture and Animal Husbandry
In this paper, the effect of different land-use types on soil organic carbon (SOC) and Paniculate Organic Carbon(POC) was studied by analyzing the soils in the meadow and conversing land of grassland to cropland in ecotones of agriculture and animal husbandry. It is shown that, compared with meadow, rotations of P/O and P/C will reduce SOC in 0-30cm soil layers by 47.54%-65.11% and 34.16-64.26% and POC by 16.90%24.48% and 11.94%-20.29%, respectively. And SOC in meadow is more than in conversing land of grassland to cropland (P<0.05). Conversing grassland to cropland in ecotones of agriculture and animal husbandry will decrease the contents of SOC and POC.
