Google 地图 API 调用方法
<script src="http://maps.google.com/maps?file=api&amp;v=2&amp;sensor=false&amp;key=ABQIAAAAfTijNJRwTtzuEuPS72TiIhQ2t05OQWL8J078r_73bb24OLcHJhQA8BkAAkk9TSo6nUzycDft-OVNpQ" type="text/javascript"></script>
    <script type="text/javascript">

        function MapLoad() {

            mapLoad.addControl(new GLargeMapControl());                
            mapLoad.addControl(new GMapTypeControl());  
            var latlng = new GLatLng(<!--{$tudes[longitude]}-->, <!--{$tudes[latitude]}-->);

            mapLoad.addMapType(G_PHYSICAL_MAP);                          
            mapLoad.setCenter(latlng, 13);

        }
        window.onload=MapLoad;
        window.onunload=GUnload;

网站给DIV统一加了overflow:hidden;导致地图无法显示，所以加了两个样式
<style type="text/css">
        #MapLoad {overflow:visible;}
        #MapLoad div{overflow:visible;}
    </style>

<div id="MapLoad" style="width: 100%; height: 550px;"></div>
