本文旨在論述沈德潛（1673-1769）建構詩學史觀之策略及其朗現的意圖與意義。沈德潛一生有關於詩學之論著，主要有二個向度：一、編寫輯錄四部詩歌選集，二、撰寫詩話《說詩晬語》；此二向度呈示什麼樣的詩學觀點與意圖呢？蓋沈氏通過別裁諸書的選定，包括《唐詩別裁集》、《古詩源》、《明詩別裁集》、《國朝詩別裁集》四部選集，以「選詩定篇」的方式，為唐前、唐、明、清諸朝裁定詩選範本，其目的顯然是作為學詩矩範，而《說詩晬語》則以論述中國詩歌體式、源流、評騭詩家、銓品時代風格等項為主，作為論述詩學的基源；從此二面向可知沈德潛的策略擬藉由「選詩定篇」與「論述存說」雙軌並進的策略樹立自己的詩學史觀，一則以別裁諸書作為範本，一則以《說詩晬語》作為理論的根據，二者合軌，共構沈德潛的史觀，提出：尊詩騷、卑六朝、倡唐詩、貶宋詩、反明詩、正清詩的詩史觀點，而其意圖何在呢？一、本於詩教，推尊《詩經》；二、倡導唐詩，以別裁諸書作為學古法式；三，以意運法，神明變化；四、對當時詩學流派之承繼與駁議調合。整體觀之，沈德潛的詩學史觀建構在唐詩的趣向，指出時人學詩的一條路徑。
