    Wouldn't it be better to only hide the previously shown div? So;

    var selection = 0;
$('#select').change(function() {
  $('#form' + selection).hide();
  selection = $(this).val();
  $('#form' + selection).show();
});

    Do note that IDs should not start with numbers, but the above should do it.

    $('#select').change(function() {
   $('#form1, #form2, #form3').hide();
   $('#form' + $(this).find('option:selected').attr('id')).show();
});

    Something like this? 

    var optionValue = $("#select").val();

$('#form1, #form2, #form3').hide();

switch(optionValue)
{
case 1:
  $("#form1").show();
  break;
case 2:
  $("#form2").show();
  break;
case: 3:
  $("#form3").show();
  break;
}

    If your forms are large, you can put them in separate files like this,

    $(document).ready(function() {
     $('#select').change(function() {
         $("#myform").load(this.value);
     });
 });


<select id="select">
<option value="blank.htm">Select A Form</option>
<option value="test1.htm">option one</option>
<option value="test2.htm">option two</option>
<option value="test3.htm">option three</option>
</select>

<div id="myform" ></div>
