Spatio-temporal changes in annual accumulated temperature in China and the effects on cropping systems, 1980s to 2000
Open accessAbstract
Change in thermal conditions can substantially affect crop growth, cropping systems, agricultural production and land use.In the present study, we used annual accumulated temperatures >10°C (AAT10) as an indicator to investigate the spatio-temporal changes in thermal conditions across China from the late 1980s to 2000, with a spatial resolution of 1 × 1 km.We also investigated the effects of the spatio-temporal changes on cultivated land use and cropping systems.We found that AAT10 has increased on a national scale since the late 1980s.Particularly, 3.16 × 10 5 km 2 of land moved from the spring wheat zone (AAT10: 1600 to 3400°C) to the winter wheat zone (AAT10: 3400 to 4500°C).Changes in thermal conditions had large influences on cultivated land area and cropping systems.The areas of cultivated land have increased in regions with increasing AAT10, and the cropping rotation index has increased since the late 1980s.Single cropping was replaced by 3 crops in 2 years in many regions, and areas of winter wheat cultivation were shifted northward in some areas, such as in the eastern Inner Mongolia Autonomous Region and in western Liaoning and Jilin Provinces.

An optimum annual accumulated mean daily temperature above 10°C is considered to enable more successful biodiversity recovery.
“Whilst an optimum annual accumulated mean daily temperature above 10 ◦ C is considered to enable more successful biodiversity recovery (Dong et al., 2009)”
From A meta-analysis of environmental responses to freshwater ecosystem restoration in China (1987–2018) (2023) · cites this paper as Dong et al., 2009
The Introduction describes annual accumulated temperature above 10°C as an indicator of thermal conditions for crop growth, and §4.2 discusses its effects on cropping systems. Neither passage addresses an optimum temperature for biodiversity recovery; searches for biodiversity recovery and species diversity found no such finding in our copy. (LLM, conf=0.76)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
