| 摘 要： | The role of organic matter in the formaiton and stability of soil aggregates in mulberry plantation in the Hang-Jia-Hu Plain,northern Zhejiang Province,was evaluated in this study,A positive correlation was found between water-stable aggregate contents and organic matter contents in the ulberry plantation soils,which supported the hypothesis that organic matter was the main eenting agent in formation of aggregates.A close correlation was also foud between statility ofaggregate ad organic matter contents.Regression analysis showed that total nitrogen content was also an idicator of water-stable aggregate content and stability.The aggregate size distribution indicated that the water-stable aggregats 1-0.25mm in diaeter with the decreast of aggregate sizes,and the aggregates 1-0.25mm in diameter had the maximum organic matter content.
