Liu also notes that the same lack of water that later caused the Han immigrants from the south to bypass the Taoyuan-Hsinchu-Miaoli plateau and continue on into the Taipei basin tended to keep the plateau's prehistoric settlements relatively small. The Chienshan site is one of the very few large settlements on the Taoyuan plateau.
從量來說，劉益昌表示，由於桃竹苗台地缺水，正如二、三百年前從南往北開墾的漢人來到新竹後，便跳過此地直接進入台北盆地一樣，史前人類在此也少有大型聚落，而大園尖山遺址則是整個桃園台地罕見的大型遺址。
