整合操作鍊、實踐理論的技術選擇取徑，論述社群依照所處環境、傳統或者外在接觸所提供的種種可能性做出選擇，其總和反映在器物展現、個體行為上，便形成行為或技術風格；運用操作鍊分解器物製作過程，將其中的選擇加以顯示、數據化，可進而檢視社群之選擇傾向。結合技術選擇概念及屬性分析的應用，可依此初步辨識群體之間的細微差異，乃至於嘗試辨識、討論社群邊界。本文選擇植物園文化的三個遺址為對象，透過上述理論取徑以及分析方法，觀察被歸類為相同文化的史前人群，在面對不同環境資源時，會否在陶器製作上有因地制宜的情形，產生相同文化風格下之微地理變異。並以此比較結果為基礎，延伸探究社群間製作技術的偏好、對於製作傳統的堅持程度，乃至於社群認同、社群邊界等議題。研究結果顯示，遺址之間陶器製作呈現高度一致性，可能隱含著較高程度的社群認同。

This research applies the approach of technical choice that integrates the concept of chaîne opératoire and practice theory to discuss the choices a social group makes in response to their environment, tradition, and external contacts. The totality of these choices is reflected in artifacts and individuals and forms a technical and behavioral style. The concept of chaîne opératoire allows us to break down the manufacturing process of an artifact and to accentuate and digitize the choices manifested in each step when we examine the preferences of a community. Using technical choices and attribute analysis, archaeologists are able to identify the subtle differences among communities and to discuss and identify possible social boundaries. Focusing on three communities of Chihwuyuan (Botanical Garden) Culture at different sites, this study applies the abovementioned methodology to examine whether prehistoric groups of the same culture maintain similar pottery manufacturing traditions or make changes to adapt to different environments that eventually lead to local variation. Issues of technical preferences, the continuation of tradition, and social identity and boundaries are also explored. We find that the three communities maintained similar pottery manufacturing techniques and postulate a strong cultural group identity among the three.
