The impact of photovoltaic construction in subsidence areas on soil enzyme activity characteristics

This study analyzes the soil enzyme activity characteristics of photovoltaic construction in subsidence areas based on the measured data and discusses the impact of photovoltaic development on soil enzyme activity. The results show that SPA, SSA, SCA, and SUA showed the lowest values among the three different positions at the R-PVP position. Compared to the CK position, SPA, SCA, and SUA all increased in the F-PVP position, but SSA levels decreased. Compared to the CK position, the SPA increased in the M-PVP position, while the SSA, SCA, and SUA slightly decreased. Compared to the CK position, R-PVP showed a decrease in soil enzyme activity. Overall, the soil enzyme activity at the R-PVP site showed a decreasing trend compared to the control area.
