Photovoltaic power station construction support

Do PV power stations change vegetation condition before or after construction?

To assess the ecological impact of PV power stations, we used the NDVI to measure the change in vegetation condition before and after the construction of PV power stations and constructed NDVI changes for PV power stations constructed in different years.

Do PV power stations affect the ecological condition?

Admittedly, this study selected only NDVI as the indicator characterizing the ecological condition to assess the ecological effect of PV power stations. In future research, it is necessary to carry out field observation at large-scale PV power stations in desert areas to assess their effect on local microclimate and biodiversity.

How are PV arrays arranged in the construction of PV power stations?

In the construction of PV power stations, the distribution of PV arrays is usually concentrated in areas with gentle terrain, while their arrangement in areas with undulating terrain takes more consideration of the influence of topographic factors, resulting in a large variance in spacing between PV arrays.

Can epvi improve the accuracy of national-scale PV power stations?

EPVI inclusion can improve the mapping accuracy of national-scale PV power stations, with China’s total PV installation area in 2020 estimated as 2635.64 km 2, achieving an overall accuracy of 0.9756 and a Kappa coefficient of 0.9394.

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 to identify the construction time of PV power stations?

Following that, we identified the construction time of the PV power stations by identifying the turning points of the normalized construction land index (NDBI) time series from 1990–2022 using the LandTrendr method.
