查询官网得到解决方案如下：
To prevent queries that request unlimited numbers of features (e.g., empty WHERE statements and statements that are always true), use MaxRecordCount to set the maximum number of features.
By default, the maximum for ArcGIS Server 10.0 is 1000 features (and 500 features for for ArcGIS Server 9.3).
You can modify this for a specific MapService in its configuration file. For a default windows installation, the file is C:\Program Files\ArcGIS\server\user\cfg\[YourMapService].cfg
步骤一：找到arcgis安装目录下你发布的地图文件的 config配置文件（本机：E:\Program Files\ArcGIS\Server10.0\server\user\cfg目录下）
步骤二：在此文件中修改<MaxRecordCount></MaxRecordCount> 节点数值后，重新启动ArcGIS Server Object Manager服务后，即可
