Spatiotemporal variation of cultivated land ecosystem
The stability of cultivated land ecosystem is crucial to the green and high-quality development of agriculture. Revealing its spatio-temporal differentiation is an important
Therein, centralized photovoltaic power stations in terrestrial ecosystems cover the earth's surface, which leads to changes in land use and has a significant effect on the surface energy balance and precipitation regimes, altering soil nutrient cycling and plant productivity, and ultimately significantly affects ecosystem functions and services.
We aimed to address these gaps by considering seven factors constraining the construction of centralized PV power stations (CPPS) and developing an indicator system based on terrain, climate, soil, and economic factors.
Overall, the photovoltaic power stations improved the quality of the soil condition, especially in harsh environments, and increased the vegetation coverage.
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.
Urbanization construction should include cultivated land from the perspective of total farmland. The balance between requisition and compensation does not consider the decline in the quality of farmland or grain production capacity. Cultivated land protection should guarantee stability of food production capacity.
As the case study shows, it is possilble to arrange permanent basic farmland as the core system for cultivated land protection and practice grade protection system on cultivated land outside permanent basic farmland zones to strictly limit farmland conversion into construction land.
