                                    id: features[j].properties.PLACE_NAME,
                                    polygon: {
                                        hierarchy: zuobiaos,
                                        material: colorObj[grades[j]],
                                        //material: Cesium.Color.fromCssColorString('rgba(234,222,13,0.5)'),

您好，您可以参考API文档http://support.supermap.com.cn:8090/webgl/Build/Documentation/Entity.html?classFilter=entity，在entity的description属性中写入图层的id。
