Abstract
Taking topsoil soil (0-20 cm) in Guide County of Qinghai Province as research object,nutrient content of soil including organic matter,alkaline hydrolysis nitrogen,available potassium,effective iron,effective zinc,was analyzed using GIS and the county territory farming resource management information system.Change rule,spatial distribution rule and change reasons of these kinds of nutrient content were studied.The result indicated that the available potassium,high level area of effective zinc content of the high level of the total area separately was 61.48％,99.26％ respectively;low level area of organic matter content of the total area was 48.05％;Area of alkaline hydrolysis nitrogen content in the relatively high level of the total area separately was 53.16％;The area of effective iron content in low level account for the total area 72.96％.关键词
