文县耕层土壤养分空间分布研究
Study on the Spatial Distribution of Arable Laye Soil Nutrient in Wenxian
摘要
Abstract
According to the basic principles of spatial interpolation, and the kriging interpolation Law of Arcgis software, analyzing the spatial interpolation on soil organic matter, nitrogen, available phosphorus and available potassium measured data in 2008, then obtaining the spatial distribution of the four kinds of soil nutrients . In the light of the analysis of the township soil nutrients distribution, using the classification function of Arcgis software, and The Gansu Province Soil Nutrient grading standards, finally drawing the conclusion that the spatial distribution of Wenxian soil nutrients was the contents of organic matter and available potassium are rich, but this area was lack of alkaline hydrolysis nitrogen and available phosphorus.关键词
