摘要Some studies have demonstrated that leaf wax delta Dn-alkane values for a single species varied significantly with seasons. However, it is still not clear that the seasonality patterns of leaf wax delta Dn-alkane values in higher plants. Meanwhile, few efforts have been pursued to assess the effect of the light slopes (sunny vs. cloudy) on leaf wax delta Dn-alkane values. In this study, we systematically investigated plant wax delta Dn-alkane values and soil n-alkane delta D values along different light slopes in different seasons (spring vs. autumn), as well as the relationship of n-alkane delta D values between plant leaves and soil. We found that plant wax delta Dn-alkane values were D-enriched by ca. 20%0 in spring relative to autumn, and ca. 10 parts per thousand in the sunny slope than in the cloudy slope. Moreover, surface soil n-alkane delta D values varied consistently with plant wax delta Dn-alkane values for different seasons and light slopes. More importantly, plant wax delta Dn-alkane values showed clear seasonal variations, but varied slightly with light slopes. The variations of plant wax delta Dn-alkane values can be recorded in soil n-alkane delta Dn-alkane values. In addition, we found that leaf wax delta Dn-alkane values in a majority of species differed significantly among woods, non-woods and grasses at a site. Therefore, we suggested a good choice to sample at the site dominated by woods when leaf wax delta Dn-alkane values are utilized as a proxy for the reconstruction of the paleoenvironment.
