| 摘 要： | 目的]定量评价渭干河—库车三角州绿洲(简称渭—库绿州)不同土地利用方式下的土壤质量,为该区域土地资源的合理利用与规划以及土壤质量的管理与治理服务。方法]基于渭—库绿洲实地采样数据,利用土壤质量评价指标,采用土壤质量指数(SQI)综合评价法,在ArcGIS 9.3软件支持下对研究区土壤质量的空间分布状况进行定量评价。结果]不同土地利用方式下的土壤质量指数的平均水平存在显著差异(p0.05),其土壤质量由高到低的顺序依次为:林地耕地荒漠灌丛盐碱草地,其中林地的平均土壤质量指数为0.48,盐碱草地的平均土壤质量指数为0.24。结论]从空间分布上,渭—库绿洲的土壤质量总体处于中低水平,只有研究区中部区域具有较高水平的土壤质量。不同土地利用方式下土壤质量差异明显。

| Abstract: | Objective] Quantitative evaluation of soil quality under different land use patterns of the Weigan-Kuqa river delta oasis was carried out in order to serve the rational use and the planning of regional land resources, as well as the management and control of soil quality. Methods] Based on the sampling data of different land use types in the Weigan-Kuqa river delta oasis, the spatial distribution of soil quality in the study area was evaluated quantitatively using soil quality evaluation index and the integrated evaluation method of soil quality index(SQI) with the support of ArcGIS 9.3. Results] There were significant differences in the averaged soil quality index between different land use patterns(p<0.05). The soil qualities of different land use types ranked as: forest > cultivated land > desert shrub > alkaline grassland. The averaged soil quality index of forest and alkaline grassland were 0.48 and 0.24, respectively. Conclusion] The overall soil quality of the Weigan-Kuqa river delta oasis was evaluated as middle or low level, except a little high level was observed at the central region of the study area. The differences of soil quality were significant among different land use patterns. |
