土壤温度上升对某些土壤化学性质的影响(英文)

Effects of Soil Warming on Some Soil Chemical Properties

土壤温度变化导致微生物群落组成及其活性产生变化；某些微生物群落成员在较高温度时有能力代谢那些在较低温度时不能被利用的基质；因此，土壤温度上升将影响土壤生态系统中的C、N、S 循环。大多数研究结果显示，温度对土壤溶液中的溶解态有机质和土壤有机磷组分有较大的影响。这些结论对预测全球气候变化对土壤的影响有重要的意义。

Change in soil temperature induces the changes in the microbial community composition and their activity; some communities at higher temperatures have the ability to access to or metabolize substrates that are not used by members of the microbial community at lower temperatures; therefore, increases in soil temperature will influence the C, N and S cycling in soil eco-systems. Most research results indicated that temperature has the effects on concentrations of dissolved organic matter in soil solution and on composition of soil organic P. These conclusions are significant for predicting the effects of global climate change on soil.
