Abstract

Based on wind, cloud and precipitation data of 79 meteorological stations over the Hebei province, the atmospheric environmental capacity (AEC) was calculated by applying A value method, climate change characteristics and trends of AEC were analyzed. The time points of abrupt change for AEC was tested by Mann-Kendall and Moving-T technique. Based on EOF analysis, the temporal and spatial variation features of AEC were studied. Results show that the climatic value of seasonal spatial distribution characteristics of AEC is relatively consistent, northwest of Zhangjiakou and Chengde area is significantly greater than the other parts, and Hebei Piedmont is lower than the surrounding, climatic value of AEC changed from high to low throughout the year. From 1972 to 2013, the annual and seasonal AEC have been observably decreasing in most part of Hebei and the abrupt change point is spring in 1983, summer and autumn both in 1998, winter in 1988. The first 2 eigenvector of EOF reflect the most characteristics of annual and seasonal spatio-temporal distribution of AEC from 1972 to 2013, the first eigenvector of contribution rate is more than 43%, reflects holistic characteristics in the whole province, the corresponding time coefficient indicates that there is an interdecadal weakening trend of AEC.

Key words： Hebei province; atmospheric environm; spatio-temporal dist
