摘要: 土壤质量评价,是农业可持续发展研究的重要内容之一,对土地资源的科学利用和管理具有重要的现实意义。基于库车县实地采样数据,采用土壤质量指数综合评价模型(SQI),在ArcGIS地统计分析模块的支持下,对研究区土壤质量指数进行克里格(Kriging)空间插值。研究结果表明:库车县耕层土壤的质量指数多在0.3~0.6左右,少数区域的SQI值在0.3以下及0.6以上;在空间分布上,土壤质量指数总体上呈带状和斑块状分布,土壤综合质量在南北方向高于东西方向,且由绿洲中部向绿洲外围递减的变化趋势,研究区中部区域的土壤质量较周围区域的土壤质量好。

Abstract: The comprehensive evaluation of soil quality has important practical significance on the scientific utilization and management of land resources, and it is an important part in the research of agricultural sustainable development. Based on the field sampling data of Kuqa County, the authors adopted comprehensive evaluation model of soil quality index (SQI), and with the support of geo-statistics analysis module in ArcGIS, carried out the (Kriging) spatial interpolation of soil quality index. The research results showed that the soil quality index of arable layer in Kuqa County was mostly 0.3-0.6, SQI value of minority areas was less than 0.3 or more than 0.6. The spatial distribution of soil quality index showed a banded and patches shape distribution, soil comprehensive quality in the north and south direction was higher than that in east and west direction, and the trend decreased from the middle of oasis to oasis periphery. Due to the impact of human activities during cultivation, soil quality in the middle of the study area was better than that of the surrounding area.
