鍋穴，壺穴巖石上深深的圓洞，由於急流或瀑布的水渦帶動疏鬆的石塊旋轉而成( 1 ) in newly - constructed stage and early stage of reclamation, the most important factor of runoff is 30min rainfall intensity. in later stage of reclamation, the most important one is 45min rainfall intensity. and the runoff capacity is the most important influence factor to soil erosion always ; ( 2 ) on the certain degree, loosening surface has an active function to infiltration condition but not to conserve soil ; ( 3 ) the most runoff is formed on platform of stackpile and the soil erosion often happens in the slope ; ( 4 ) stone - soiled dumps have an advantage over soil at respect of erosion resistance so that soil is not adapt in covering slope ; ( 5 ) grass has a better role in conservation of water and soil than arbor in early stage of reclamation ; ( 6 ) arbor - arboret - hemp mix is the best model for conservation
結果顯示：在未復墾時期和復墾初期， 30min降雨強度對徑流影響最大，復墾後期徑流與45min雨強相關性最強，而徑流量對土壤侵蝕量的影響始終最大；通過疏鬆地表巖土只在一定程度上改善地表的入滲條件，並不能起到保土的作用；平臺為徑流的主要形成區，而土壤侵蝕主要集中在斜坡；土石混排坡的土壤抗蝕性比覆土坡的要大得多，在排土場形成過程中不宜用厚層黃土覆坡；在復墾初期，純草模式水土保持效果明顯好於純喬模式。Due to low burying depth and weak diagenesis, the formation is loosely solidified, which shows an immature stage of diagenesis
館上段地層埋藏較淺，成巖作用弱，巖石疏鬆，為早期成巖階段的產物。
