新疆甘家湖湿地边缘带土壤酶活性研究
Study on Soil Enzyme Activity in the Marginal Zone of the Ganjiahu Wetland in Xinjiang
摘要
Abstract
In this study, the activity of 4 soil enzymes affected strongly by different vegetation communities, anthropogenie factors and murine in the marginal zone of the Ganjiahu Wetland was lucubrated. The results are as follows ： （ 1 ） The activity of urease and eatalase was in an order of Phragmites australis community 〉 Populus euphratica community 〉 Holoxylon ammodendron community 〉 Aneurolepidum chinense community, that of proteinase in an order of A. chinense community 〉 P. australis community 〉 P. euphratica community 〉 H. ammodendron community, and that of sucrase in an order of P. australis community 〉 H. ammodendron community 〉 P. euphratica community 〉 A. chinense community; （2） Temporally, the maximum values of urease, catalase and proteinase contents occurred in August, and the minimum ones in May or October, but the maximum value of sucrase content occurred in May, then it was decreased gradually, and increased to some extent in October; （3） Vertically, urease and proteinase contents in P. australis and H. ammodendron communities were decreased with the increase of soil depth, but the sucrase content was decreased at first and then increased with the increase of soil depth; （4） Linear regression analysis revealed that total N and organic matter content were the important factors affecting soil enzymatic activity; （5） Impact of trample on soil enzyme activity was serious, reclamation could increase the activity of these enzymes, especially that of urease and catalase. Impact of grazing on urease and proteinuse was also serious. In addition, all the peak values of urease, catalase, proteinase and sucrase occurred in August; （6） The contents of urease, catalase, proteinase and sucrase were low iF the areas with mice destruction compared with that in the mice-free areas, especially the content of urease. The increase rates of activity of these enzymes in the areas with mice destruction were lower than those in the mice-free areas during the period from May to August.关键词
