| 摘 要： | 不同利用方式对土壤肥力质量有着重要的影响.选取吉林省西部地区盐渍化草原5种不同利用方式:放牧草原、围栏草原、旱田、新开水田、老水田,分析测定了土壤的主要养分,并利用土壤质量指数法(QI)和土壤退化指数法(DI)定量研究方法分析了这5种土壤肥力质量和土壤肥力退化指数.结果表明:放牧草原QI值为22.56%、围栏草原66.56%、旱田11.90%、新水田77.11%、老水田82.34%;以放牧草原为基准其退化指数显示:旱田为负值,其他利用方式均为正值,水田和围栏草原值较高.结果均揭示水田和围栏草原土壤肥力质量较高,而放牧草原和旱田土壤肥力质量较低,呈退化趋势.

| Abstract: | Different land utilization methods have important effects on soil fertility quality.Five different land utilization methods of saline steppe soil in the west of Jilin province were selected,including grazing grassland,fencing grassland,tillable,new paddy field and long-term cultivate paddy field.The main nutrients of the soils were determined.Soil fertility quality and soil fertility degradation were determined by using quantitative analysis method of soil quality index(QI) and soil deterioration index(DI).... |
