| 摘 要： | 在土地质量评价前,为了使未采样的空白图斑有一个最接近实际的值,需要对赋值方法进行研究,可以最大程度地保证评价结果的合理性和真实性.选取1 km2赋值研究区,采集样品30件,利用三种不同赋值方法进行赋值评价,研究结果表明按照耕园草图斑10件/km2的采样密度,开展屈家岭管理区1:5万土地质量地球化学调查,利用距离加权反比...

| Abstract: | Before land quality evaluation,in order to make the unsampled blank map have the closest value to the actual value,the authors studied the assignment method to ensure the rationality and authenticity of the evaluation results to the greatest extent.In the study area of 1 km 2,30 samples were collected and evaluated by three different evaluation methods.The results showed that the sampling density of 1∶50000 in Qujialing Management area was 10 pieces/km 2 in order to meet the requirements of land quality evaluation,the method of distance weighted inverse ratio or moving average can be used to assign value to the whole area,and then the land quality grading and evaluation can be carried out. |
