如果你阅读http://codex.wordpress.org/Class_Reference/WP_Query#Taxonomy_Parameters 它详细地概述了您需要的一切。看一下下面从codex中提取的代码示例。它应该可以帮助您：）

$args = array(
    \'post_type\' => \'Article\', /* This is where you should put your Post Type */
    \'tax_query\' => array(
        array(
            \'taxonomy\' => \'people\',
            \'field\' => \'slug\',
            \'terms\' => \'bob\'
        )
    )
);
$query = new WP_Query( $args );
