- Abstract
Huang-huai-hai River basin is an important grain production area and economic zone of China. Under the impact of global warming, energy resources are changing all around the world. Studying the ≥ 10 °C accumulated temperature (AT10) is of great importance for the food security and economy of Huang-huai-hai River basin. The slope of AT10 and Mann-Kendall statistical test were applied to quantify the trend magnitude and detect the significant trend respectively. And the distribution pattern and movement characteristics had been analysed with GIS technology. The results shown that AT 10 of Huang-huai-hai River basin has an increasing trend during since 1960s; AT 10 has a moving tendency towards the northwest and decreased from the southeast region towards the northwest region. The ratio between active area and stable area in different classes has fluctuated during the study period.
