Spatial and temporal evolution and greenhouse gas emissions of China's agricultural plastic greenhouses.

The rapid development of the use of agricultural plastic greenhouses in China in recent years has played an important role in the generation of economic benefits from agriculture. However, it has also led to severe negative environmental impacts. Thus, it is necessary to explore the spatial and temporal evolution of agricultural plastic greenhouses in China as well as their environmental impacts so as to obtain a deeper understanding of agricultural intensification and the sustainable development of the facility agriculture industry. To this end, this study analyzed the spatial and temporal evolution characteristics of agricultural plastic greenhouses and their greenhouse gas emissions within the 2000-2020 period based on the extraction of the spatial distribution of greenhouses in China in 2000, 2010, and 2020. Landsat imagery and statistical data combined with the random forest classification method as well as life cycle analysis, were used in this study. The results obtained showed that: (1) Within the 2000-2020 period, the area covered by agricultural plastic greenhouses in China expanded from 1594.66 to 11,838.77 km
