| Abstract: |
| Carbon storage heterogeneity of 10 kinds of 3-year-old plants in depression between karst hills
were studied. The results showed that：（1）There were some differences for carbon holdup in the same organ of
different plants or different organs of one plant，the average carbon holdup of plants was 40.49% in depression
between karst hills，the order of carbon holdup showed as shrubs ＞ trees ＞ vines，the values were 43.21%，
40.25% and 38.11% respectively，the variation coefficient of Cerasus humilis was the largest and it of Myrsine
africana was the least，the values were 8.28% and 1.66% respectively.（2）The carbon storage of different
organs in the same plant performanced as follows： carbon storage of trunk was the highest except Ficus tikoua，
the carbon storage of different organs of trees and shrubs appeared as trunk ＞ branch ＞ leaf except Eriobotrya
japonica，Toona sinensis and Mallotus repandus（trunk ＞ leaf ＞ branch），the carbon storage of different organs
of vines appeared as trunk ＞ leaf ＞ branch ＞ root，and the carbon storage of the same organ in different plants
was different.（3）The proportion of trunk carbon storage in total carbon storage of appeared as trees ＞ shrubs ＞
vines. |
