Although this has led to a discussion, no-one as far as I can tell has actually tried to answer Wenlei Zhou's question.

Hope this helps:

I can create a link from my dataset to yours just by including a triple in my dataset with one of 'your' URIs as object.

<http://mysite.com/id/1> <http://example.com/some-predicate>  <http://yoursite.com/id/ABC>

You can also declare information about links between datasets in metadata about your dataset, using the voiD ontology - see http://vocab.deri.ie/void

If you are thinking about the Linked Data Cloud diagram (see http://richard.cyganiak.de/2007/10/lod/) then that is generated every few months by Richard Cyganiak and Anja Jentzch, using some criteria listed on that web page - the dataset must be at least 1000 triples and contain at least 50 links to other datasets already in the diagram - and you have to make  sure Richard or Anja knows about it.
