| 摘 要： | 基于2005—2007年典型干旱区塔里木盆地南缘的策勒绿洲的试验数据，根据当地农民的耕作习惯选择4种典型的农田利用强度（高投入农田、常规投入农田、新垦农田和绿洲内部农户农田），利用产量可持续性指数(SYI)、土壤改良指数(SI)和土壤综合质量指数(QI)分析了不同土地利用强度下农田土壤质量的变化情况.结果表明：各样地的土壤有机质（SOM）、碱解氮（AN）和速效磷（AP）含量均存在显著差别；位于绿洲边缘的新垦农田在所有评价中均处于最低水平，而绿洲内部农田则处于相对较高水平.本研究结果不但有利于当地农田的合理开发利用，同时有利于农田生态环境的保护. |

| Abstract: | Based on the 2005〖KG-*2〗-〖KG-*7〗2007 experimental data in Cele oasis in the southern margin of Tarim Basin of Xinjiang, the soil quality of four typical types of farmland with different utilization intensity, i.e., farmland with high input, farmland with normal input, newly reclaimed farmland, and farmland in oasis’ interior, was analyzed and assessed by using sustainable yield index, soil improvement index, and soil quality synthesis index. Among the farmlands, there were significant differences in the contents of soil organic matter, available nitrogen, and available phosphorus. Newly reclaimed farmland had the lowest level of soil quality, while the farmland in oasis’ interior had relatively higher soil quality. This study could help the reasonable exploitation and utilization of farmlands in Cele oasis, and the protection of local farmland eco-environment. |
