以浙江舟山已进行生态恢复的矿山为对象,研究海岛矿山人工土壤的养分变化。结果表明:在2～5 a的生态恢复过程中,土壤养分呈现出逐步增加的趋势,土壤有机质含量、全钾含量和脲酶活性与恢复年限在0.01水平上显著正相关。此外,土壤全钾含量还与坡向在0.05水平上显著负相关,坡位同土壤养分的相关性不显著。经主成分分析:不同坡向上的土壤养分得分表现为阴坡>阳坡>半阴坡>半阳坡,不同坡位上的土壤养分得分表现为下坡>上坡>中坡。 Taking the mines with ecological restoration in Zhoushan, Zhejiang Province as an example, the nutrient changes of artificial mines in island mines were studied. The results showed that in the course of ecological restoration from 2 to 5 years, soil nutrients showed a gradual increase trend. Soil organic matter content, total potassium content and urease activity had a significant positive correlation with recovery time at 0.01 level. In addition, the content of total potassium in the soil was also significantly negatively correlated with the slope direction at the level of 0.05. The correlation between slope position and soil nutrient was not significant. According to the principal component analysis, the scores of soil nutrients in different slopes showed shady slope> sunny slope> semi-shady slope> semi-sunny slope. The soil nutrient scores of different slope positions showed downhill> uphill> mid slope.
