Abstract:: Three runoff residence communities with different measures for water conservation were chosen to investigate the three residence communities which are covered by Paspalum natatu: the entire covered park, the entire mulched park and no vegetation park. The soil organic matter in different slopes and depths, and the relationship of the spatial heterogeneity between TN, TP had measured and analysed. The results indicated that: (1) the organic matter content increased first and then reduced with the increase of soil layers. The organic matter content had no significant change from the top to bottom of the slope. The organic matter content of the entire covered park increased, and the organic matter content in the no vegetation park increased first and then reduced; (2) TN reduced as the soil layers became deeper, and there’s no significant difference between the treatments, the TN content on the slope presented as the sequence: the entire covered park > the entire mulched park > no vegetation park, the treatment of the entire mulched park had concentration effect on the middle of the slope, and TN contents of the treatments of the entire covered park and no vegetation park decreased from the top to the bottom; (3) TP content reduced as the soil depth increased, reduced gradually in the entire covered park and increased first and then reduced in the entire mulched park and no vegetation park, on the slope, the TP content followd the order: the entire mulched park > the entire covered park > no vegetation park, and it had concentration effect on the middle of the slope. This study could provide scientific basis for recovery of the nutrients of the red earth slope land in subtropical zone.
