چکیده
As the largest artificial ecosystem on Earth, croplands not only secure basic living materials for people but also provide ecological service values human society. For croplands, services have proven to be of great value and are closely linked activities climate change. However, spatiotemporal patterns cropland their drivers still need further assessed quantitatively. In this study, we provided a comprehensive evaluation across China's ecosystems over past two decades using gross product (GEP) as single metric monetary final services. The material services, regulating cultural were calculated summarize GEP in China. Our results showed that multiyear mean was 4.35 × 10 7 million CNY. reached 3.86 CNY, followed by 4.76 6 CNY 1.16 5 different among provinces, leading heterogeneous spatial pattern associated with population cultivated area. Moreover, analyzed trends at provincial national scales. has increased period. material, regulating, rate (0.35 ± 0.01) −1 , (1.12 0.10) (0.002 0.0002) respectively ( P < 0.05). majority provinces had an increasing trend GEP, yet some developed e.g., Beijing Shanghai, decreasing trend. Furthermore, evaluated impacts social-economic natural factors changes GEP. We found rising prices agricultural products boosted increase Meanwhile, adjustments planting area each province. Overall, our findings highlight importance assessing decision-makers.

Ecosystem Productivity and Carbon Flows: Patterns across Ecosystems
The characterization and understanding of carbon flows in aquatic and terrestrial ecosystems are topics of paramount importance for several disciplines, such as ecology, biogeochemistry, oceanography, and climatology. Scientists have been studying such flows in many diverse ecosystems for decades, and sufficient information is now available to investigate whether any patterns are evident in how...
متن کاملChanges in Earth's reflectance over the past two decades.
We correlate an overlapping period of earthshine measurements of Earth's reflectance (from 1999 through mid-2001) with satellite observations of global cloud properties to construct from the latter a proxy measure of Earth's global shortwave reflectance. This proxy shows a steady decrease in Earth's reflectance from 1984 to 2000, with a strong climatologically significant drop after 1995. From ...
