Highland barley (Hordeum vulgare Linn. cv. nudum Hook. f.) is the principal cereal crop over the Tibetan Plateau (TP). The response of highland barely to climate change in the past decades, especially in terms of yields still remains uncertain. In this study, its responses to climate change were investigated using daily weather data and agriculture data during 1961–2018. The results showed that the annual mean air temperature over the TP increased at 0.33 °C per decade during 1961–2018, and the rate of warming increased with altitude, reaching 0.41 °C per decade at altitudes of 4500–4700 m. The growing degree days (GDDs) increased by 9.6% during 2011–2018 compared with the 1960s, whereas low temperature degree days (LDDs) decreased by 40.3% over the same period, indicating that the thermal conditions for highland barley cultivation have improved. A strong relationship was observed between the yield of highland barley and LDDs (−0.76, p |
