| 摘 要： | 本文通过对花江喀斯特地区花椒人工林演替过程中部分土壤碳转化酶的活性以及不同活力活性有机碳研究,得出在喀斯特地区花椒人工林中随着种植年限的增加,土壤中活性有机碳的含量不断上升,生态环境处于恶化的变化过程中。并且通过对花江地区常绿阔叶林、灌丛以及荒草地与碳有关的土壤酶的活性研究,证明在群落从高级向低级演替过程中,酶的活性降低,活性有机碳的含量增加,生态环境恶化。

| Abstract: | The article study soil enzyme activities and the content of soil organic carbon in Zanthoxylum Bungeanum forest in Karst area of Huajiang in Guizhou Province,the results shows: the content of oxidizable organic carbon was increased with the increasing of plantation age in karst area,which implied karst eco-environment declined.Soil enzyme activities were analyzed in forest,bush,badlands and Zanthoxylum bungeanum forest,the content of dissolved organic carbon also increased with the community of plant evolved from superior to inferior,and eco-environment was declined by planting Zanthoxylum bungeanum. |

| Keywords: | organic carbon soil enzyme rock desertificated karst area Huajiang |
