  5. The organic matter influenced > 0. 25 mm soil particle aggregation and > 0. 5 mm water - stable soil particle aggregation slightly and played an important role in the aggregation of > 5 mm water - stable soil particles. the percentage of aggregates destruction were remarkably negatively related with content of > 5 mm water - stable soil particle aggregate, and ultimately negatively related with > 0. 25 mm water - stable soil particle aggregate, which meant the content of water - stable soil particle aggregate dropped as the rise of percentage of aggregates destruction, the loosely fe took a role in increasing content of water - stable soil particle aggregate. the main factor that affecting content of > 0. 5 mm water - stable soil particle aggregate was percentage of aggregates destruction, whereas organic matter and percentage of aggregates destruction were the dominating matters that influencing content of > 0. 25 mm water - stable soil particl

    粘粒含量在各級團聚體的形成過程中起著一定的作用；有機質對0 . 25mm團聚體、 5mm水穩定性團聚體有一定作用，對0 . 25mm水穩定性團聚體起顯著作用；團聚體結構破壞率與5mm水穩定性團聚體成顯著負相關，與0 . 25mm水穩定性團聚體達到極顯著負相關，說明結構破壞率越大，水穩定性團聚體的數量就越少，反之越多；游離鐵含量對促進水穩定性團聚體方面起一定的作用，影響0 . 5mm水穩性團聚體含量主要是結構破壞率，而影響0 . 25mm水穩定性團聚體含量的是有機質和結構破壞率。
