Actually I'd recommend you to create your own list type: create a directory /models/fields/year.php which will extend JFormFieldList class defined in /libraries/joomla/form/fields/list.php

And add there the following code:

<?php
defined('JPATH_PLATFORM') or die;

JFormHelper::loadFieldClass('list');

class JFormFieldYear extends JFormFieldList
{
    protected $type = 'Year';

    protected function getOptions()
    {
        $options = array();         
        $yearNow = date('Y');

        for ($i = 1950; $i <= $yearNow; $i++)
        {
            $tmp = JHtml::_('select.option', $i, $i, 'value', 'text', false);
            $options[] = $tmp;
        }

        reset($options);

        return $options;
    }
}

And then in your xml type define type="year" instead of type="list" for a field like this:

<field name="joinyear" type="year"
        description="COM_USERS_REGISTER_JOINYEAR_LABEL"
        filter="string"
        label="COM_USERS_REGISTER_JOINYEAR_DESC"
        message="COM_USERS_REGISTER_JOINYEAR_DESC"
        required="true" />
