The variation of water-stable aggregates, nutrients and their correlation in four land uses (upland, paddy soil, vegetable soil and wasteland soil) under different reclamation years were studied. The results showed that the content of >5 mm aggregates decreased rapidly after the wasteland soil was cultivated to upland, paddy soil and vegetable soil. With the reclamation years prolonged, the total content of >0.25 mm aggregates increased. The accumulation rate of soil organic C was higher than soil N for upland and vegetable soil, but kept stable for paddy soil. The content of soil P increased rapidly with the reclamation years prolonged in red soil. And in this study, soil K run off seriously and the content of soil K decreased with the reclamation years prolonged. Soil organic C and soil N were significantly correlated with the content of water-stable aggregates, but soil P and K were not significant correlated with the content of water-stable aggregates. So the level of stability of water-stable aggregates was mainly depended on the balance of soil organic C and soil N.
