He didn't directly base them on any particular persons or other characters, but he did draw inspiration from his own life.
Tolkien was in love with Edith Bratt, who eventually became his wife, but was forbidden by his guardian to marry her until he turned 21.
We can see two similar relationships in Tolkien's legendarium, in the love of Beren and Luthien (which can be read about in The Silmarillion) and in the love of Aragorn and Arwen. In both cases there is a father figure who does not allow Beren and Aragorn to take the hand of their daughters until they have proven themselves in some way.
The importance of his own tale of Beren and Luthien to Tolkien is quite clear, as he had 'Beren' engraved on his tombstone, and 'Luthien' on his wife's. He has also mentioned that the tale of Aragorn and Arwen is the most important of the tales in the Appendices.
But that's not to say Tolkien was aiming for a simplistic reading one might get from an everyday romance story, or that Tolkien intended solely to project his experience onto these stories. On one level the tales of Beren and Luthien and of Aragorn and Arwen function as simple romances and as something that was part of Tolkien's own experience, but they can be read much more deeply than that, of course.
J.R.R. Tolkien based the characters Aragorn and Arwen on his own relationship with his wife, Edith. Arwen represents Edith, while Aragorn embodies Tolkien himself. Their love story mirrors Tolkien's deep affection for his wife and influenced the romantic subplot in "The Lord of the Rings."
It depends on whether you are talking books or movies. For movie fans, the answer may be Arwen Evenstar - Played by Liv Tyler. (For real LOTR fans, also known as Arwen Undómiel) However, the character of Arwen is radically changed in the film from the books. In the books she is a marginal character who shows up fleetingly at official functions, and, although important as the intended spouse of Aragorn, does not really play any part in the story. A much more important woman is Galadriel, who maintains the elf-kingdom of Lothlorien and tests the resolve of the company of the Ring. In return Frodo tests her resolve by offering her the ruling ring. She passes the test. The female character about whom we hear the most in the book is Eowyn, the desperate and courageous shield-maiden of the Rohirrim, by whom alone Sauron's greatest captain may be killed.
"The Lord of the Rings" by J.R.R. Tolkien was dedicated to his wife, Edith. Tolkien referred to her as his "Luthien," after a character from his Middle-earth mythology who is known for her beauty and bravery.
Morwe and Nurwe were the two spouses of Nienna, a Vala known for her grief and compassion. They are rarely mentioned in Tolkien's works, and not much is known about them other than their relationship to Nienna.
Your question could be interpreted two ways. Viggo Mortensen is the actor whom portrays Strider in the Lord of the Rings motion pictures - Strider is the alias used by Aragorn, son of Arathorn and heir to the throne of Gondor when he is traveling as a Ranger of the North. He is also known as Estel to the Elves. Strider is a name given to Aragorn by men who know only his legend and not who he really is. Aragorn is a decedant of numenor; the island in which all of mankind in LOTR lived on until their ambition drove them away from the island. This explains his prolonged life, as the men of numenor lived well into their 300th years. (Aragorn is roughly 85 in the time that the LOTR trilogy takes place)
