英文摘要	The conversion of grassland to agricultural land is an important land use change that affects soil stocks and concentrations of C, N and P, as well as their stoichiometric ratios. However, the response mechanism of soil C, N and P change to grassland conversion remains unclear. Here, we conducted a meta-analysis of 92 studies and showed that the C and N stocks mainly depended on soil depth, conversion duration and precipitation, while the P response was insensitive to these factors. Moreover, C, N and P losses were also correlated with soil physical-chemical properties (pH, sand, silt, clay). Changes in the response ratios of C:N, C:P and N:P indicated that soil C and N were more sensitive than P to grassland conversion. These results suggest that land use management policies should protect natural grasslands, especially in the arid and semi-arid regions, to minimize soil C, N and P loss.
