| 摘 要： | 以郑州市6个公园绿地为研究对象，采集0～20 cm土层的108份土壤样品，测定其理化性质和土壤酶活性，并对其土壤酶活性及其与土壤理化性质进行相关性分析。结果表明，碧沙岗公园尿酶活性及磷酸酶活性最强，滨河公园过氧化氢酶活性最强，郑州绿博园多酚氧化酶活性最强；尿酶与速效钾呈正相关关系，与过氧化物酶呈负相关关系；过氧化氢酶与非毛管孔隙度、磷酸酶呈正相关关系，与速效磷、多酚氧化酶呈负相关关系；磷酸酶及蔗糖酶与土壤容重呈负相关关系，与非毛管孔隙度呈正相关关系；磷酸酶、蔗糖酶与水解性氮、阳离子交换量、有机质含量呈正相关关系；蔗糖酶与非毛管孔隙度呈正相关关系；多酚氧化酶与理化性质不相关。根据研究结果判断，土壤酶活性可以作为土壤肥力评价指标。

| Abstract: | To test physi-chemical characterastics and enzymatic activity of soil , soil samples varies from 0 to 20 cm was collected from 6 city parks in Zhengzhou , and correlation analysis between enzymatic activity and physico-chemical characterastics was conducted as well .The results showed the urease and phosphatase activity of Bayside Kong Park was the strongest , catalase activity of the Riverside Park was the strongest , polyphenol oxidase enzyme activity of Zhengzhou Green Garden of was the strongest;There was positive correlation between the urine enzyme and available potassium , and negative correlation between the urine enzyme and peroxidase; The catalase had pos-itive correlation with both and non-capillary porosity and phosphatase , while had , negative correlation with availa-ble phosphorus , polyphenol oxidase; The phosphatase and invertase showed negative correlation with soil bulk density , but positive correlation with non-capillary porosity; The phosphatase and sucrose enzyme had positive cor-relation with hydrolytic nitrogen , cation exchange capacity , and organic matter; The invertase had positive corre-lation with the non capillary porosity; the polyphenol oxidase had no correlation with the physical and chemical properties.Based on the results of this study , the soil enzyme could be used as important index for soil quality e-valuation . |
