Is there a geospatial dataset for PV power plants in China?

The proposed framework generated a geospatial PV dataset with 3712.1 km 2 in China by 2022. At present, there are two high-quality geospatial datasets of PV power plants that can be publicly available for China (Kruitwagen et al., 2021; Zhang et al., 2022).

Are PV power plants expanding in different regions of China?

The uncovered expansion patterns of PV power plants in different regions of China hold significant value for understanding PV development and its land occupation in both space and time.

Do PV power plants promote poverty alleviation in China?

The diffusion of PV power plants in China is accompanied by not only the national wide carbon mitigation goal but also the simultaneous advancement of PV poverty alleviation in China's fourteen poverty-stricken areas (PSAs) (Ge et al., 2019; Zhang et al., 2020). Thus, the expansion patterns within and without PSAs are examined and compared.

Are China's PV power plants stable?

The clear spatial and temporal expansion variation suggests that China's PV power plants has the continuous and stable deployment of large-size centralized power plants in the western provinces during this period from 2010 to 2022 and the accelerated installation of small-size distributed power plants in the eastern and central provinces from 2017.

Is China's PV power plant performance better than U-Net?

Our IoU is 11%, 14.31%, and 17.22% higher than that of U-Net, Zhang et al. (2022), and Kruitwagen et al. (2021), respectively. The four metrics reveal superior performance of China's PV power plants extracted by the proposed framework compared to two existing datasets and the class U-Net.

Where are PV power plants located in China?

The PV power plants in eastern and central China mainly established on croplands (24.6%) and the occupation of croplands presents a significant reduction of 48% from 2017 to 2022.
