在黄土峁状丘陵区研究比较了隔坡梯田、大台田、大鱼鳞坑3种坡地的治理模式,指出坡地工程治理能有效地提高坡地接纳降雨能力,提高土壤含水率,但大面积的坡地治理会破坏原有植被及土壤结构,引起40 cm以上表层土壤水分蒸发强烈;同时大台田处理侧坎水分散失严重,距田坎愈近其散失强度愈高;在坡地种植强根系、高耗水的人工林会加剧土壤干层的发育,影响林分自然更新能力。
The Gexi minefield is located to the northeast of Shikengdong mine area,all identified structures are controlled by multiple boreholes,the F11 fault is a reverse fault,evidence is tendered that the fault has extended into Shikengdong mine area,but is deemed to a normal fault(F5),thus to use data of boreholes Nos.
隔溪井田位于石坑岽矿区的东北,已查明的构造形态由多个钻孔控制,井田内的F11断层为逆断层,资料证实该断层延伸至石坑岽矿区,但在石坑岽矿区被确定为正断层(F5),为此利用隔溪井田中的10、17、23号钻孔资料及石坑岽矿区已有研究成果,对矿区内多条断层进行了重新解释,认定石坑岽矿区F5即为隔溪井田的F11逆断层。
