摘要
A composited soil fertility indices was identified to assessment geochemical land quality based on the abundance of nutrient elements in topsoil,which derived from a regional geochemical exploration in Longhai city,Fujian province,and then the statistic properties of element abundant distribution and fertility indices correlation were analyzed,as well as the level of fertility indices was subsequently classified,and then the quality of land was assessed in this study,which conclude that the abundance of soil organic,nitrogen,phosphorus was inclined to deficient,whereas the abundance of soil organic,nitrogen,phosphorus was appropriate underlying a heterogeneous background of nutrient element distribution,which indicated the essential of application fertilization balance to improve soil fertility in respect of soil quality assessment in this study.
