Abstract: Integrated weighted clustering method was applied to pl
an the monitoring points for agricultural products security. Definite amounts of
 key monitoring sampling points were mined out from enormous monitoring objects
to make the fewer monitoring sampling points cover the product categories, yield
s, and regions as more as possible. Among the 10172 agricultural products securi
ty enterprises all over the China, 246% of them were selected. The tested cate
gories, yields, and regions of agricultural safety products covered 3271%, 44
29%, and 75% of the total, and their coverage increased by 280%, 1085%, 5
56%, respectively, compared with that by using conventional monitoring and man
agement methods, which suggested that it could be more effective to apply integr
ated weighted clustering method in setting the monitoring points for agricultura
l produc
ts security.
