运用地统计学方法,研究河北省赵县地区土壤养分的空间变异性,探讨不同土地利用方式对土壤养分含量空间分布的影响.可为土壤肥力的评价和管理提供理论依据.结果表明:全量N、K、Fe、Mn为弱变异性,全量P、Cu、Zn为中等变异程度;全量N、K、Fe、Cu具有强烈的空间相关性,全量P、Mn、Zn则为中等强度的空间相关性;全量P与Zn具有相似的空间分布规律,全量K与Mn具有相似的空间分布规律,全量Cu与N、Fe则具有相异的空间分布规律;土地利用对Cu、Zn的影响大于其他元素.

Geostatistics was used to study the spatial variability of soil nutrients in Zhaoxian county, Hebei Province, and to discuss how different land use manners can impact the spatial distribution of soil nutrients. The results showed that the spatial variability of total -N,K,Fe, Mn was weak, and total - P,Cu,Zn was moderate; total - N,K,Fe,Cu have exhibited strong spatial correlation, and total - P, Mn, Zn exhibited moderate spatial correlation, the findings suggested that total - P and total - Zn showed a similar pattern in distribution, total - K and total - Mn had a similar pattern in distribution too, the spatial distribution pattern of total - Cu was completely different from that of total - N and total - Fe. In addition the spatial variability of total -Cu,Zn were more greatly affected by land use manners than the others. These results provide a firm scientific foundation for soil fertility assessment and management.
