- Abstract:
- 4 typical land use of Linyi Shandong Province were taken as a case study. The influence of different land uses on soil nutrients and fertility was analyzed. The result indicated that different land use had significant effect on organic matter (OM), but had no significant effect on pH, total phosphorus (TP), total nitrogen (TN), total kalium (TK) and particle composition. The order of contents of OM in different land use types was paddy field >unutilized land>forest land>dry land. The order of content of TN in different land use types was unutilized land>forest land>paddy field>dry land. The order of content of TP in different land use types was unutilized land>dry land>forest land>paddy field. The order of content of TK in different land use types was forest land>paddy field>dry land>unutilized land. Correlation analysis indicated that the correlation coefficient among different nutrients of dry land was larger than paddy field, forest land and unutilized land. Different land use types had no significant effect on the relativity between TP and TN. The component analysis indicated that the order of the comprehensive fertility index F of dry land, paddy field, forest land and unutilized land was paddy field(0.86)>forest land(0.78)>dry land(0.51)>unutilized land(0.43).
