  5. The features of these sequences arerbefore sequence i deposited during the rapid subsidence of the depression, the range of the sediment is limited. sequence ii is the first series of source and reservoir rocks of the depression. there are regional unconformity at the bottom of the sequence iii. the rock type are variety. this sequence is evaluated as good source rock, sequence iv is associated with the first section of duhongmu formation, thick mudstone at the bottom and the thick single sandston are the main rock type. this sequence are evaluated as good source rock and reservoir. sequence v associated with the second and the third section of duhongmu. which is mainly mudstone and can be regional capping rocks

    層序對應于阿爾善組二段，為深色泥巖與砂礫巖不等厚互層，是本區的第一套烴源巖和儲集層，可以作為本區儲層。層序對應騰格爾組，此時凹陷擴張，沉積層底部具有區域性的沖刷面，巖性變化大，是較好的生油層。層序對應都紅木組一段，下部泥巖發育，單砂層較厚，是主要的生油層和儲層。
  6. There are 3 types of reservoir for the continuing subsidence type basin, there are diapir reservoir, fault reservior, drape reservoir, and the source rock is apart from the reservoir, they are contact by fault ; and there are anticline reservoir, fault reservoir, incline reserve ir, mudstone reservoir under the denudation area, and the source rock is contact with the reservoir

    以沉降為主要趨勢的盆地的油氣藏有底辟構造油氣藏、斷層油氣藏、披覆構造油氣藏，其烴源巖與油藏在空間上是分離的，並通過斷層相連；剝蝕區以下的油氣藏有背斜油氣藏或斷層油氣藏、向斜油氣藏及泥質巖油氣藏，其烴源巖和油氣藏可有密切的接觸關系。
  7. The disaster of drought and waterlog is severely and frequently, the water and soil loss and rock desertification is increasing, the subsidence is happened at some ground, the bio - diversity decrease, the vegetation and soil evolve conversely, the productivity declines, the people lives in difficulty, and the most phenomenon and types of ecological problem are concentrated in karst area. to strengthen studies on karst ecological characteristics and degradation types can provide gist for ecological rehabilitation and reconstruction in karst area, but also can provide means for reference for other ecology area
