- 摘要:
- 采用全球卫星定位系统（GPS）和地理信息系统（GIS）技术，对黑龙江省依安县农田土壤速效养分进行了空间变异特征研究。结果表明：黑龙江省西部依安县土壤中氮、磷、钾的含量比较丰富，土壤缺硫和锌。土壤中硫、磷、硼、锰的空间分布具有明显的变异性。土壤中硫空间分布的偏斜程度较大。pH与有机质、有效锰、有效硼和有效锌都极显著相关；有机质与有效锰极显著相关。
- Abstract:
- Spatial variability in Yi’an county of Heilongjiang province was studied using the technology of Global Positioning System(GPS)and Geography Information System(GIS). The results showed that the black soil in the west of Heilongjiang province was relatively rich in fertilities; the content of nitrogen,phosphorus and potassium was fairly abundant,but the content of sulfur and zinc was lacking. The variation of spatial distribution of sulfur，phosphorus，boron，manganese was obvious. The declining degree of the spatial distribution of sulfur was fairly high. pH and organic matter,effective boron,efficient manganese and effective zinc were extremely significant correlative. Organic matter and effective manganese was significant correlative.
