Abstract:
There are lots of problems in the implantation of monitoring points, such as the randomness and turbid hierarchical structure of the monitoring points、the redundancy of the monitoring data and so on. Applying the spatial cluster principles, the authors make cluster analysis on the monitoring points and the monitoring indicators of chose in Langfang region. The assessment and contrast of the variability of the original data and the transacted data by cluster analysis are done, which proves that the cluster analysis is reasonable and valid. Combing spatial clustering analysis with spatial variety may provide the theoretical evidence for the re-implantation of the monitoring net, and the possibility to improve the representativeness of the monitoring net. It also provides the theoretical principles to confirm the monitoring indicators by figuring out the correlation between the monitoring points and the monitoring indicators, and then to establish the foundation for the further research of environmental management, pollution controlling and comprehensive utilization of environmental resource.
