姑苏繁华图
清乾隆二十四年（1759年），擅长人物、花鸟草虫的苏州籍宫廷画家徐扬用了24年时间创作了一幅名为《盛世滋生图》长卷，并以散点透视技法，反映当时苏州“商贾辐辏，百货骈阗”的市井风情，又名《姑苏繁华图》，进献乾隆皇帝，以赞乾隆盛世。这是继宋代《清明上河图》后的又一宏伟长卷，全长1225厘米，宽35.8厘米，比《清明上河图》还长一倍多，具有极大的历史价值，为国家一级文物。
《姑苏繁华图》画面自灵岩山起，由木渎镇东行，过横山，渡石湖，历上方山，介狮和两山间，入苏州郡城、经盘、胥、阊三门，穿山塘街，至虎丘山止。作者自西向东，由乡入城，重点描绘了一村（山前）、一镇（苏州）、一街（山塘）的景物，画笔所至，连锦数十里内的湖光山色、水乡田园、村镇城池、社会风情跃然纸上。
粗略计算，全幅画有各色人物1万2千余人，各色房屋建筑约2140余栋，各种桥梁50余座，各种客货船只400余只，各种商号招牌200余块，完整地表现了原作中气势宏伟的古城苏州市井风貌，是研究250年前“乾隆盛世”的形象资料，具有极大的历史价值。画卷布局精妙严谨，气势恢宏，笔触细致，十分细腻地刻画出了江南的湖光山色、田园村舍、阊胥城墙、古渡行舟、沿河市镇、流水人家、民俗风情官衙商肆，描绘了苏州城郊百里的风景和街市的繁华景象，形象地反映了18世纪中叶苏州风景秀丽、物产富饶、百业兴旺、人文荟萃的繁盛景象，具有很高的艺术鉴赏价值。

  清乾隆25年，钦天监观测到来年正月初一有“日月同升，五星联珠”天文异象，是“海宇晏安，年谷顺成”的祥瑞征兆，乾隆帝因此命令画院画家徐扬绘图记录这一罕见天象。
画卷前中段绘有观象台，上并有浑天仪、天体仪两座观测星象的仪器，观象台两侧天空各画日、月。卷中人物虽小，仍可见相互走告、观看天象之态，更因当日为元旦，贺岁拜年的姿态也穿插其中，写实历历。考文献纪录，当年正月五星位置确实相近，但未冠以“五星联珠”之称。或许正如款识所言，虽天象有兆，却未“ 宣付史馆”，而由徐扬此图扮演着与“文献”同功的纪实效能。
画卷中，文武官员进京朝贺，市井百姓也纷纷出门拜年，从故宫内城城墙、观象台起，经东单牌楼，到皇城内东安门、东华门止，北京东城区重要地标都浓缩在长卷中，画面描绘新春胡同巷道车马游人络绎不绝、街面店铺鳞次栉比，展现出乾隆盛世北京市井的繁华富庶景象。
长卷中描绘的路径，许多地标建筑仍然建在。例如观象台从明朝建成至今仍保存完好，清朝时有多件天文仪器，乾隆9年乾隆皇帝上观象台发现没有自制天文仪器，下令自制，10年后设计制成“玑衡抚辰仪”，与其他7件天文仪器到现在仍在北京观象台顶，从北京建国门地铁一出来就看得到。
日月合璧五星联珠图与清明上河图
 “日月合璧五星联珠图”出自清朝西画大师郎世宁弟子徐扬之手。整幅画高48．9公分，长1342．6公分。主要描绘清隆26年繁荣情景；同时记载清代的科学技术，颇具有历史价值。它比“清明上河图”还要长2米，虽然布局类似清明图，但却画出清代的科学突破。清明上河图是北宋画家张择端存世的仅见的一幅精品，它描绘了北宋都城汴京清明时节的繁荣景象，是中国十大传世名画之一。而日月合璧五星联珠图描绘乾隆二十六年农历正月初一，乾隆盛世皇都市井繁华的富庶景象。
徐扬为江苏苏州人，于乾隆十六年（西元1751年）高宗南巡苏州时献画，因此进入乾隆朝如意馆任职。相关作品如《盛世滋生图》（西元1759年）长卷，描写苏州繁盛景象；以及《乾隆南巡图》之记述乾隆历巡江南的景象。本图卷亦属任职宫廷画院之作，旨在描绘“日月合璧、五星联珠”之罕见天象，用以称颂皇帝德政。
 

乾隆十四年（1749年）九月，两江总督黄廷桂、河道总督高斌、漕运总督瑚宝、副总河张师载、安徽巡抚卫哲治、江苏巡抚雅尔哈善、两淮盐政吉庆联名上奏，合词恳请巡乾隆幸江南。
乾隆十六年（公元1751年）正月十三，在皇后嫔妃、随从大臣及2000多护卫人员的前呼后拥下，乾隆皇帝的銮驾浩浩荡荡地通过午门，开启了他帝王生涯中第一次南巡之旅。
乾隆皇帝效仿祖父康熙皇帝，曾6次巡幸江南，一方面督促地方政务，彰显天子圣明；另一方面则纵情山水之间，借此摆脱宫廷生活的寂寞。乾隆南巡是声势浩大的政治活动，兴师动众，开支浩繁；地方官吏投其所好，无不曲意逢迎，铺排极尽奢华。
随从乾隆第一次南巡的宫廷画家徐扬也奉命绘制了《乾隆南巡图卷》。《图卷》以中国画传统的写实手法描绘了乾隆皇帝南巡途中省方问俗、察吏安民、巡视河工、阅兵祭陵等场景，同时也展现了士民工商的风情世态，以及黄河、淮河、长江、大运河沿岸及西湖等地的锦绣江山，和保留了“康乾盛世”珍贵的历史记忆。
《乾隆南巡图卷》有绢本、纸本各一套12卷，凡24卷，总长度达150米，堪称清代一系列叙事画中的鸿篇巨制，是理解叙事性绘画作品在清代宫廷绘画中所扮演角色的关键性作品之一。但徐扬的乾隆南巡12卷画卷从宫廷失散，目前全球各地博物馆只有6卷，其他画卷下落不明，在中国国家博物馆和纽约大都会博物馆都有珍藏。乾隆南巡图一共十二卷，分别为：
第一卷启跸京师。描绘乾隆十六年（1751年）正月十三日清高宗乾隆皇帝弘历奉皇太后钮祜禄氏自乾清门启銮后，出正阳门，右转沿西河沿大街西行，过宣武门前，出广宁（安）门，过宛平县拱极城，至卢沟桥，再过长新（辛）店、塔洼，前往良乡县黄新庄行宫的情景。图卷总68.6厘米，横1988.6厘米。
第二卷 过德州
第三卷渡黄河
第四卷 阅视黄淮和工
第五卷 金山放船至焦山
第六卷驻跸姑苏。乾隆自二月十七日离金山，行经镇江府城、丹徒、丹阳、常州府城，到无锡县城，游秦氏寄畅园、惠山寺，于二月二十日御舟驻跸无锡县北望亭。二十一日，御舟启行，通过湖桥，进入苏州府长洲县界的南望亭镇，本卷即于此开始。图卷纵68.6厘米，横2171.9厘米。
第七卷 入浙江境到嘉兴烟雨楼
第八卷驻跸杭州。乾隆自二月二十八日离开嘉兴，经石门、塘栖，三月初一日到达杭州，驻跸于圣因寺行宫。本卷描绘乾隆沿西湖苏堤游览的情景。图卷纵68.6厘米，横1126.4厘米。
第九卷 绍兴谒大禹庙
第十卷江宁阅兵。描绘乾隆十六年（1751年）五月初四日，乾隆皇帝奉皇太后南巡回京，进入天安门后，经端门，走向午门，即将进入紫禁城的情景。图卷纸本设色，纵68.6厘米，横985.8厘米。
第十一卷 顺河集离舟登陆
第十二卷 回銮紫禁城
《南巡纪道图》上有楷书题签：“南巡纪道图，臣徐扬恭绘”，表明了作品名及作者。长卷自西向东，由京城入江南，以“乾隆南巡”经历的村镇城池为表现重点，描绘了千里江山的繁华景色。整个画卷气势恢宏，构图精妙严谨，笔触细致，胜似宋代宫廷画家王希孟的《千里江山图》。
 在《南巡纪道图》中标注的地名，也是乾隆游历时经过的地方，画家徐扬将熟悉的山川景色和“乾隆南巡”途径的地点融入画卷之中，以视觉图像的方式，记录下南巡这一历史行程经历的地点。徐扬选取“南巡”作为表现点，致力于表现京城至苏州的繁荣盛况，实则是歌颂乾隆时期的太平盛世。该卷前后共有9方清代鉴藏印章。最早是乾隆帝钤盖的“乾隆御览之宝”、“三希堂精鉴玺”、“宜子孙”3方印章; 继其后，嘉庆帝、清末帝宣统又各自钤盖了各朝的收藏印。此外，长卷还著录于《石渠宝笈》，卷上有“石渠宝笈”和“宝笈三编”两方印章。这些收藏印章是作品从乾隆一直流传到宣统时期的印证。
从画作本身价值来看，《南巡纪道图》继承了我国宋代以来风俗长卷画的传统，吸收《清明上河图》等作品精华之处的同时，其形式、内容诸方面都有突破。继其后，徐扬还完成了《乾隆南巡图》、《姑苏繁华图》等作品。这些作品都是画家根据乾隆时期重大的历史、政治事件完成的，作品构图宏伟、制作繁浩，每一个长卷都浓缩了乾隆盛世的军政大事和社会生活场景。《南巡纪道图》是其中完成较早的作品，可谓开先河之功。
更为特别的是，徐扬在《南巡纪道图》上标注了从京城至苏州一路上著名的城池山岳之名，使作品不仅具有艺术欣赏价值和收藏价值，更对研究乾隆时期的地理具有重要的参考价值。
从史料记载来看，徐扬当属乾隆皇帝身边一位炙手可热的画家。清代胡敬曾在《国朝院画录》中对徐扬有简单的介绍：“字云亭，吴县人，官内阁中书。《石渠》著录三十有五，续编载有恭绘《南巡图》十二卷。”乾隆南巡之时，看中徐扬的绘画才能，将其召入宫中，“授内阁中书”，成为乾隆帝的“御用画师”。
传统中国绘画史研究往往集中于历代推崇的精英画家和文人艺术家，而忽视对职业画家和宫廷画家的研究。近年来，受到西方美术史研究的启发，很多研究者转向更为广阔的“视觉艺术”研究，在此学科下，像徐扬这样的宫廷画家的作品受到关注。《南巡纪道图》是研究200多年前乾隆盛世的形象资料，集艺术价值和文献价值于一体，不仅是清代宫廷绘画的力作，而且是清代美术史研究重要的参考图像，具有极为重要的史料价值和研究价值。
