葡萄规模种植区土壤因子的空间异质性分析

依据GIS技术，以浦江县葡萄规模种植地的土壤试验数据为基础，结合多年农户调查探讨葡萄规模种植区土壤因子的空间演化规律。结果表明，土壤中不同因子受土壤自然环境影响差异较大，pH易受土壤母质、地形特征等结构因子的影响，速效磷则主要受随机性因素影响，其他因子变化是结构因子和随机因子共同作用所致。Kriging插值结果显示，土壤因子含量变化与农户养分投入之间密切相关，表明，尽管葡萄种植面积实现了规模化，但农户养分投入却未实现标准化，测土配方、精细养分管理技术的应用有待加强。...

Summary:依据GIS技术，以浦江县葡萄规模种植地的土壤试验数据为基础，结合多年农户调查探讨葡萄规模种植区土壤因子的空间演化规律。结果表明，土壤中不同因子受土壤自然环境影响差异较大，pH易受土壤母质、地形特征等结构因子的影响，速效磷则主要受随机性因素影响，其他因子变化是结构因子和随机因子共同作用所致。Kriging插值结果显示，土壤因子含量变化与农户养分投入之间密切相关，表明，尽管葡萄种植面积实现了规模化，但农户养分投入却未实现标准化，测土配方、精细养分管理技术的应用有待加强。

In this paper, GIS combined factor with data of peasant household survey for years was applied to analyze the spatial variation characteristics of soil factor in grape growing areas, based on the soil test data at Pujiang County. The paper showed that different factors varies in different soil environment regions, pH value was greatly influenced by structure factors such as soil parent material,topographic feature; soil available phosphorus was really affected by random factors; the rest of the factors was the combined influence of structure factors and random factors. The result of kriging interpolation demonstrated that the soil fator are closely related to Farmers input. Although the scale of grapes planted had been realized in area, input of farmers had no regularity. The Conclusion that the application of soil testing and formulated fertilization and nutrient management technology was obviously deficiencies and was to be strengthene
