The traditional Chinese garden principle of “Borrowed Scenery”（Jiejing） was transformed into a quantitative control tool for modern spatial design to address the issues of single spatial hierarchy and the dissolution of regional characteristics in current landscape construction in water-network villages.Key quantitative indexes including viewing distance （D），relative height of scenery （H），the D/H ratio， and the vertical viewing angle （α） were extracted to construct a parameterized design paradigm encompassing remote borrowing，adjacent borrowing， upward borrowing， downward borrowing， and seasonal borrowing by introducing visual perception psychology and spatial geometry theory and analyzing the traditional “Borrowing Landscape” principle based on the Yoshinobu Ashihara’s theory of external space design.The Fuzi shan Area in Yangxin County， Hubei Province， a region characterized by both hilly terrain and water networks was used as an example to conduct an empirical study.The results showed that “remote borrowing”was achieved through visual corridor control， effectively enhancing the sense of spatial depth in natural open interfaces where D/H>4.“Adjacent borrowing” strategies and controlled building setback distances were used to achieve a flexible integration of the village and the mountain for the mid-range scale where 1≤D/H≤3.“Downward borrowing” perspectives were used to expand the horizontal extensibility of the natural landscape in areas close to landscape features with significant height differences （D/ΔH<1）.It is indicated that the interpretation of the “Borrowed Scenery” principle based on spatial geometric parameters will provide a scientific and quantitative basis for constructing modern rural landscapes.
