摘要:
采用统计学与地统计学相结合的方法,结合GIS技术,对河南省襄城县植烟田耕层(0～20 cm)159个土壤样本进行了数据处理,分析了土壤有机质、pH、速效氮、有效磷和速效钾含量的空间分布特征,结果表明:土壤pH的变异系数最小,而有效磷由于不同的耕作措施和不均衡施肥,其变异系数最大。半方差分析表明,土壤有机质、pH和有效磷符合球状模型,最大相关间距分别为21 020、19 150和8 460 m,而有效氮和速效钾符合指数模型。最大相关间距分别为7 484和25 320 m,土壤pH的C0/sill为0.193 5,具有强烈的空间自相关性,而其他四种土壤肥力因子的C0/sill为0.352 8～0....
Abstract:
It is essential to understand spital variability of soil properties in tobacco planting regions, for the right decision can be made as to how many fertilizer rates are likely to be appropriate for the high quality tobacco production. In this paper, a total of 159 soil samples were taken from surface soil(0～20) of Xiangcheng tobacco planting fields,Henan province in April 2007 for examing the concentration of soil organic matter, pH,available N, available P and available K .Spatial variability of above mentioned was evaluated using geostatistics and geographic information system(GIS) analyses. The objective of this study was to provide a scientific basis for field management targeting at improving soil quality in this tobacco planting region. The results showed that among those five soil fertility factors, the variation coefficient of soil pH is the smallest,while that of available P is the greatest which demands more samples under the same precisions,which are resulted from different cultivation methods and uneven fertilization.Analysis of the isotropic variogram indicated that the soil pH,organic matter and available P semivariogram were well described with spherical models,with the distance of spatial dependence being 21 020,19 150 and 8 460 m respectively,while the available N and available K semivariogram were well described with exponential model, with the distance of spatial dependence being ranged from 7 484 to 25 320 m. Soil pH value was strongly spatially dependence with C0/sill being 0.193 5,while other four soil fertility factors were moderately spatial dependent with C0/sill being range from 0.352 8 to 0.526 0. With the kriging analysids,the spatial distribution maps of soil properties in Xiangcheng tobacco planting regions was drawn.In the paper, the index system of soil fertility suitability of tobacco was established. Sor parabolatype dependence functions were developed according to their effect on tobacco crop and the function value was also calculated． AHP was applied to judge the weight of each evaluation factor． then the integrated index va1ues for every evaluation unit were obtained．And the fertility map of Xiangcheng tobacco planting regions was drawn with GIS software mapGIS. The results indicated that the optimum fields for Fluetobacco crops growth were found in the eastsouthern part of the investigated regions, accounting for 5.02% of the whole area, while the soil with suitability fields were mainly distributed in the northern and middlesouthern part of the investigated regions, occupying 80.15% of the whole area. And the fields with less suitability existed in the middle of this given regions, accounting for 14.28% of the whole area.
