Uncertainties would exist in the relationship between delta^{13}C values and environmental factors such as temperature, resulting in unreliable reconstruction of paleoclimates. It is therefore important to establish a rational relationship between plant delta^{13}C and a proxy for paleoclimate reconstruction that can comprehensively reflect temperature and precipitation. By measuring the delta^{13}C of a large number of C_3 herbaceous plants growing in different climate zones in northern China and collecting early reported delta^{13}C values of C_3 herbs in this study area, the spatial features of delta^{13}C values of C_3 herbs and their relationships with humidity index were analyzed. The delta^{13}C values of …
