Trends in agricultural heat and solar radiation resources in Northeast China: A multistage spatio-temporal analysis

摘要

Climate change has changed the distribution of climate resources in crop growing season, and caused some impacts on agricultural production. Based on daily meteorological data collected at 71 meteorological stations in Northeast China, trends at multi-temporal scales (decadal, annual, monthly, and 10-day) and spatial patterns of heat resources [temperature, frost-free period (FFP)] and solar radiation resources [growing season's sunshine hour (GSS)] are estimated over the period 1961-2012.
