Gully erosion, which is universal on original lands, but also the special forms, for example, hole erosion gravel erosion debris slide and debris flow, which is unusual in loess area, ( 2 ) based on a long - term fixed point experiments in proving ground of the south stackpile, the soil erosion factors have been researched quantitatively, the runoff and erosion affected factors have been made sure and the experiential models of producing water and soil have been taken in newly - constructed stage, early stage and later stage of reclamation

排土場原地貌的水蝕模數為3700 4400t km ~ 2 ? a ；在
排土場新造地貌上，擊濺、面蝕、細溝侵蝕、淺溝侵蝕、沉陷侵蝕、砂礫化面蝕、
土砂瀉溜和坡面泥石流等水
土流失形式出現頻率和發生程度都明顯強于原地貌。 （ 2 ）以南
排土場徑流試驗場長期的定位觀測為基礎，對
排土場未復墾時期、復墾初期、復墾後期的
土壤水蝕影響因子進行定量研究，確定了徑流和
土壤水蝕的主要影響因子及其臨界值，建立了產流產沙的經驗模型。

The results of research reveals the variation disciplinarian and the affected factor, defines the factor limiting the urban regional development. all these offer scientific references for reasonable city planning, municipal building project planning, reasonable arrangement of land use, the confirmation of land use intensity and the improving land use benefit. and a series of methods we have explored can apply the practical manipulation of grading and assessing urban land, which contribute to enhance working efficiency, shorten the time of evaluation, enhance the updating of urban land price, establish a system of dynamic superviso ry control and examination, and enhance accuracy and objectivity of urban land - rated evaluation
再由球形檢驗和主成份分析、信度分析、多元回歸分析的技術路線，逐層遞深地解譯影響城市地價的主要因素及相互數量關系，其研究結果揭示了城市地價的變化規律和影響因素、明確了限制城市區域發展的因素，為合理的城市規劃，市政建設項目規劃，合理安
排土地用途，確定
土地利用強度，提高
土地利用效益等提供了科學依據，同時探索的系列化方法可直接應用於城市定級估價的實際操作中，有利於提高工作效率，縮短估價時間，提高城市地價的現勢性，建立地價動態監控和測算系統，又可提高城市定級估價的準確度和客觀性，在理論上、學術和實踐上均有積極意義。
