Loess region China

Authors: 超级管理员 | Edit: Miao



 







In the Loess region, winter wheat was harvested from early to mid-June, while summer maize has been planted during the monitoring period. When compared to average, RAIN increased 41%, PAR accumulation (RADPAR) dropped by 3%, and temperature (TEMP) by 0.6°C. The BIOMSS production potential was 23% above the average as a result of ample rainfall. Up to June, condition of crops was below the five-year average and last year’s level, with a VCIx value of 0.80. The spatial NDVI clusters and profiles indicate that crop condition fluctuated widely over time and according to areas. Condition was favorable in northwest Henan, east Gansu, and central Shaanxi provinces, with the exception of a period in mid-June. On the contrary—and mostly because of the below average temperature (which is confirmed by the maps of potential biomass), crops were in poor condition (compared to the five-year average) in the center of Gansu and the south of Ningxia province. The fraction of arable land actually cropped decreased 5 percentage points, possibly as a result of lower temperature and below average radiation.
