中文摘要	为了探索岩溶地区石漠化综合治理的碳汇效应,以贵州毕节石桥小流域,清镇王家寨--羊昌洞小流域,贞丰顶坛小流域为研究对象,通过分析实地监测数据,分别测算了各研究区总碳存量,分析并比较了碳储量在各碳库以及不同等级石漠化之间的分布情况和大小关系.研究发现:三个研究区总碳存量仅为32 434.9tC;各碳库碳存量:土壤层植被层(草本层灌木层);碳密度在不同等级石漠化间关系表现为:轻度>中度>强度;总碳密度在各研究区中的大小关系表现为:毕节>清镇>贞丰,其中土壤层碳密度起决定性因素.此外,本文最后还提出在未来石漠化综合治理中增加碳汇监测指标,扩大石漠化综合治理碳汇研究的范围,加强岩溶作用碳汇效应基础研究等建议
英文摘要	In order to explore the effect of carbon-sink by treatment to karst rock desertification, three small catchments in Guizhou Province, including Shiqiao, Wangjiazhai-Yangchangdong and Dingtan, are taken as the study objects. In light of field monitoring data, the total carbon storage in each catchment is calculated;the distribution of carbon storage in different carbon pools and under different desertification grades is compared. It is found that the total carbon storage in 3 study catchments is only 32 434.9tC;the carbon storage distribution in each carbon pool is: soil vegetation(herbagebush) and under different desertification grade is: slight rock desertification > moderate rock desertification > intensity rock desertification;the carbon density distribution in the study catchments is: Shiqiao small catchment > Wangjiazhai-Yangchangdong small catchment >Dingtan small catchment. Besides,a series of prospect to enhance the carbon sink research is proposed by the author, such as increase carbon sink monitoring indicators in future rock desertification control plan, extend the research borderline of carbon sink, improve the basic research in the carbon sink effect of karstification
