摘　　要：运用GIS和地统计学相结合的方法研究了1983年和2007年国营阳江农场橡胶园土壤有机质与全氮的时空变异。结果表明,20多年间土壤有机质和全氮含量有所降低。土壤有机质和全氮含量的空间差异缩小,含量水平基本上有朝均衡化发展的趋势,空间变化趋于平均。这些变化主要是由人为生产管理和施肥造成。同时随着生产管理、施肥等人为活动影响的增加与积累,使得土壤有机质和全氮的空间变异减弱,朝均衡化方向发展。The temporal-spatial variation of soil organic matter and total N content in rubber plantations in Yangjiang State Farm from 1983 to 2007 was studied by using geographical information system（GIS） and Geo-statistics. Results indicated that the contents of organic matter and total N in the soil decreased in more than 20 years, and that spatial variation of organic matter and total N content of the soil was reduced, with their contents tending to be reduced at a similar level and their spatial variation tending to be similar. These changes may mainly be due to production management and fertilizer application. At the same time, with the accumulation of impact from production management and fertilizer application and other human activities, the spatial variation of organic matter and total N contents of the soil was reduced and tended to be homogeneous.
