水溶性有机碳（WSOC）被认为是最具流动性和活性的土壤碳源，其特性是土壤生态学研究的一个重要问题。采用生物降解试验对7种不同管理方式土壤中提取的WSOC进行了研究。用水（土/水比1:2，W/V）提取土壤中WSOC 30 min，然后通过液态呼吸法测试其生物降解性。研究结果证实了WSOC的生物降解性受土地利用和管理实践的双重影响。这些结果表明，生物降解性试验是表征土壤有机碳的合适方法，并为土壤肥力提供了有用的信息。
Water soluble organic carbon (WSOC) is considered the most mobile and reactive soil carbon source and its characterization is an important issue for soil ecology study. A biodegradability test was set up to study WSOC extracted from 7 soils differently managed. WSOC was extracted from soil with water (soil/water ratio of 1:2, W/V) for 30 min, and then tested for biodegradability by a liquid state respirometric test. Result obtained confirmed the finding that WSOC biodegradability depended on the both land use and management practice. These results suggested the biodegradability test as suitable method to characterize WSOC, and provided useful information to soil fertility.
