- 摘要:
- 掌握土地整理区土壤养分特征已成为烟田快速培肥和提升土壤质量的首要问题。采用GIS与地统计学相结合的方法，评价了土地整理后烟田土壤养分等肥力指标的适宜性等级状况及其空间变异特征。结果表明：研究区土壤偏酸，有机质、碱解氮含量普遍缺乏，存在较大面积的缺钾现象；各肥力指标均属于中等变异，变异系数大小顺序依次为有效磷 > 速效钾 > 碱解氮 > 有机质 > 全氮 > 全磷 > 全钾 > pH值。有机质和速效钾的变异函数比较符合指数模型，全钾、碱解氮用高斯模型拟合效果好，而pH值、全磷、全氮和有效磷则以球状模型拟合效果最佳。肥力指标的块金系数[C0/（C0+C）]中，土壤有机质、全钾、碱解氮分别为0.903，0.998，0.823，空间相关性较弱；而pH值、全氮、全磷和有效磷的块金系数[C0/（C0+C）]变化范围为0.501~0.724，具有中等空间相关性；各肥力指标空间变程为99~1 003 m，最大和最小值分别为全钾和碱解氮；各肥力指标表现出不同的空间分布特征，其中，pH值呈斑块状，碱解氮及全钾呈条带状，全磷整体上呈从北至南含量增加的梯度分布格局。
- Abstract:
- It is significant to explore soil nutrient features in tobacco field for fertilizer application and soil quality improvement in land consolidation area. The assessment and spatial variation of soil fertility indices in tobacco field after land consolidation had been explored based on a combination of geostatistics with GIS. The results showed that soil pH was relatively lower, most of soils were lacking organic matter (OM) and available nitrogen (AN) as well as potassium; all of soil fertility indices belonged to middle-grades variability and variation coefficients decreased in the order:available phosphorus (AP) > available (AK) > AN > OM > total phosphorus (TP) > total potassium (TK) > pH. Soil OM and AK were well described by exponential model, and the fitting semi-variance model for soil TK and AN was Gaussian, and the best matching effect of soil pH, TP, TN and AP was the spherical model. The results of semi-variance analysis showed that the nugget/still ratios of soil OM, TK, AN were 0.903,0.998 and 0.823, respectively, and their spatial correlations were relatively weak, the nugget/still ratios of soil pH, TN, TP and AP ranged from 0.501 to 0.724, and their spatial correlations were relatively middle. The range of different soil fertility indices varied from 99 to 1 003 m, and the values of TK and AN were the maximum and minimum, respectively. Meanwhile, its kriging map differentiated each other, such as pH embodied spotted type, AN and TK showed stripped pattern, however, TP had the type of increasing gradient distribution from the northern area to the southern area.
