保定—沧州地区基于空间自相关分析的土壤区域监测点网络密度研究

摘要

对土壤地质环境开展监测是一项重要的工作.在布设土壤监测点时,经济合理的土壤监测密度是一个必须要解决的科学问题.本文利用空间自相关理论,对保定—沧州地区土壤地质环境监测点网络密度进行了研究.结果显示,在保定—沧州地区,64km2/个土壤监测点的土壤地质环境监测密度能有效保留土壤地球化学环境信息.%As an important medium, soil environment has a close relation to human beings, and there is increasingly concern about the soil environment. Monitoring the soil geo-environment is important. Soil monitoring network must be economic and reasonable, which is needed to resolve scientifically. In this paper, soil region monitoring network optimized by spatial autocorrelation is examined in the Baoding-Cangzhou area. The results show that one soil monitoring point per 64 km2 is a reasonable density in the Baoding-Cangzhou area. With this density, soil geochemical information can be caught and maintained effectively.
