| 摘 要： | 通过辽河流域1∶25万多目标区域地球化学调查成果数据,在GIS技术的支持下,建立了由影响土地肥力、环境健康质量的16个指标组成的评价指标体系,应用隶属度函数模型及累计曲线法对辽河中下游平原进行了土地质量地球化学评价及空间分布研究。结果表明:辽河中下游平原土地质量状况较好,良好以上等级土地占研究区的89.78%,其中优质级土地占0.66%,优良级土地占63.16%,良好级占25.96%,中等级土地占10.06%,差等级土地极少,仅占0.16%。 |

| Abstract: | By the use of Multi-Purpose Geochemical Data(1:250000) in Liao River and a system of evaluation which contained 16 indexes about land fertility and environmental health,the geochemical land quality evaluation and space distribution in the Liao Middle-downriver Plain was researched based on GIS,Membership Functions and cumulative curve.The results demonstrated that land quality in researched area was in good condition,about 89.78% of land was above nicer level,with high quality level of land 0.66%,the eximio... |
