【摘要】

Leshan Giant Buddha is damaged seriously because of weathering and plant settlement

Amounts of soil organic C, N and P was accumulated in the surface of the Buddha

Soil organic C, N and P stocks under herbs are the most abundant

?Soil organic C, N and P mainly stocks in the shoulder, arm and the platform

The accumulation of soil organic matter and nutrients are important pathways in effectively understanding the mechanisms of plant settlement and rock weathering, while the characteristics of soil organic carbon (C), nitrogen (N) and phosphorus (P) under different vegetation remains unclear. In this study, the stocks and stoichiometry of soil organic C, N and P were determined in different positions and types of vegetation on the surface of the Leshan Giant Buddha. We found that the total stocks of soil organic C, N and P were 1689.77, 134.6 and 29.48 kg, respectively, for the Buddha. The stocks of soil organic C, N and P under vascular plants were higher than those under other vegetation, with highest values observed under herb. Higher stocks per unit area (m2) of soil organic C, N and P were found on the left and right arms, shoulders, and two platforms. These results provide a full primary picture in understanding soil organic C, N and P accumulation and distribution on the surface of the Buddha, which could supply the fundamental data on weathering management of the Buddha and other similar open-air stone carvings.
