| 中文摘要 | open-top chambers were used to estimate the possible effects of global warming on delta c-13 of seven plant species grown in alpine meadow ecosystem. the delta c-13 values of plant species were lower after long-term growth in open-top chambers. in the course of experiment, temperature significantly increased inside the chambers by 4 degrees c. plant species grown at a lower elevation above sea level had higher delta c-13 values as compared to those grown at a higher elevation. this was in accordance with the effect of open-top chamber on delta c-13 values in plants. greater availability of co2 and lower water vapor as indicated by an increase in discrimination against (co2)-c-13, probably result in more negative delta c-13 values of plants because higher stomatal conductance increases availability of co2 and causes greater discrimination against (co2)-c-13. the plant species studied could be the indicator species for testing global warming by the change in carbon isotope ratios at the two growth temperatures. |
