摘要:
为了研究城郊地区集约型土地利用方式对土壤性质的影响，以北京东郊的顺义区为例，利用GIS技术及地统计学对20世纪80年代土壤二次普查和2007年两期土壤有机质进行了空间分布特征的对比与分析研究。结果表明：经过20多年时间研究区土壤有机质含量整体呈上升趋势，东部与南部地区上升明显，两期土壤有机质空间分布特征总体一致，这种分布格局是自然和人为利用因素共同作用的结果。当地土地利用方式变化对土壤有机质产生正面影响，从精准农业角度出发研究结论对科学的农业管理措施具有指导性意义。
Abstract:
In order to investigate the effect of different land use on soil properties in suburban area,taking Shunyi district in Beijing east suburb as example,the spatial distribution of soil organic matter in 1980 s and 2007 were compared and analyzed based on geostatistics and geographic information system(GIS).The results showed the SOM content in the district had been increasing from 1980 s to 2007 and this increasing effect was most significant at east and north of Shunyi district.The spatial distribution in 1980 s was similar to that in 2007,which was due to natural and artificial effects.The different land use had a positive influence on SOM,which had a guidance meaning for scientific agriculture management from the view of precision agriculture.
