| 摘 要： | 对柴河流域五种主要土地利用类型中土壤有机质进行了监测,分析结果表明：柴河流域表层土壤中有机质肥力为Ⅲ级,并呈现由表层到底层自上而下递减的趋势;其相同土层的有机质含量11月的显著高于7月;7月表层有机质含量表现为设施农业〉落荒地〉林地〉坡台地〉传统农业,浓度范围为13.40～18.15 g/kg;11月表层有机质含量表现为落荒地〉设施农业〉林地〉传统农业〉坡台地,浓度范围为14.61～20.92 g/kg.

| Abstract: | The organic matter in the five main types of soils used in the Chaihe Basin was monitored in July and November,2010.The results indicated that：（1） the fertility of organic matter in the surface soil of the Chaihe basin was grade Ⅲ,and showed a decreasing trend from the surface to the bottom;（2） the organic matter content in the same soil was significantly higher in November than in July;（3） the content of organic matter in the surface soil in July showed a decreasing trend in the order： agricultural facilities wasteland woodland slope platform traditional agriculture,and the concentration varied in the range of 13.40 ～ 18.15 g / kg;（4） the content of organic matter in the surface soil in November showed the trend： wasteland land for apparatus agriculture woodland land for traditional agriculture slope platform,and the concentration range was from 14.61 to 20.92 g / kg. |
