Do solar photovoltaic power stations affect terrestrial ecosystems?

Front. Ecol. Evol., 21 March 2023 The rapid increase in construction of solar photovoltaic power stations (SPPs) has motivated ecologists to understand how these stations affect terrestrial ecosystems. Comparing study sites, effects are often not consistent, and a more systematic assessment of this topic remains lacking.

How does ecological construction affect the ESV of PV plants?

This shift in ecological construction modes has led to an increase in the FVC and corresponding ESV values for the region, with PV plants adopting M2 to M5 measures experiencing an approximately 7.2% improvement of net ESV from the completion of PV plants to 2022.

Does integrated mode promote virtuous cycle of ecological environment in PV plants?

The application of this integrated mode can accelerate the formation of organic crust on desert surfaces and gradually establish a stable green protective system, thereby promoting a virtuous cycle of the ecological environment in PV plants (Cui et al., 2017) (Figure 2D).

Does a PV plant have a potential for ecological restoration?

While this growth rate is limited, the maximum fractional growing season vegetation coverage increased from 33.6% to 57.9% during the same period (Figure 6), with the highest value observed in a PV plant adopting the M4 mode, indicating the substantial potential for ecological restoration in PV plants.

What is China doing with solar energy & sand control?

Since 2017, the Chinese government has demonstrated a heightened focus on modes such as “solar energy + sand control” and “solar energy + ecological restoration,” accompanied by the implementation of a series of policies designed to foster the development of desert ecological PV plants.

Can photovoltaic panels increase plant biomass & vegetation cover in grassland ecosystems?

Furthermore, plant aboveground biomass and vegetation cover were also enhanced by SPP construction in grassland ecosystems. In farmland ecosystems, photovoltaic panel installation increased plant aboveground biomass, soil available phosphorus and soil pH, while reducing CO 2 flux, plant species richness and vegetation cover in woodlands.
