  1. Through research, the organic matter of source rocks in carboniferous - permian coal measure strata began first hydrocarbon - generating in mesozoic, and the first hydrocarbon - filling took place. but, because of yanshan movement later, the carboniferous - permian strata rose, as a result, the first hydrocarbon - generating and reservoir - forming paused ; in early tertiary period, because carboniferous - permian strata dipping forward east originally turned into dipping forward west, the prototype of faulted block began to form gradually ; by the end of sha - 3 period of early tertiary, the paleogeotherm of carboniferous - permian strata exceed the mesozoic ' s temperature again, and accordingly, abundant hydrocarbon was generated and expulsed secondly. the trap continued to develop ; from the end of late tertiary to quaternary, the second hydrocarbon - generating and expulsing got to its peak, and the second reservoir - forming was over

    研究表明，本區石炭?二疊紀烴源巖在中生代發生一次生烴和排烴，並有油氣充注，后因燕山運動導致地層抬升，一次生烴和成藏過程中止；在早第三紀，原來東傾的地層變為西傾，斷塊圈閉開始具雛形；至早第三紀沙二末期，石炭?二疊系的大部分地層古地溫再次超過中生代一次生烴的溫度，開始二次生烴和排烴，圈閉持續發育；晚第三紀末?第四紀，二次生烴、排烴達到高峰，二次成藏完成。
  2. Based on the data of vector topographic map, the geomorphologic evolution stage of csmasp is studied with the aid of maplnfo and arc view. it is indicated that the research area is in the middle age and old age according to the davisan stage determine of geomorphologic evolution. the uplift and denuded amount in the period of neo - tectonics and the elevation of denudation surface of lincheng period ( mainly in quaternary ) are also discussed

    根據高程分析結果，認為魯中南山地主要處于流域地貌發育的壯年、晚年期，並對魯中南山地第四紀構造抬升量與侵蝕速率、各流域臨城期山麓剝夷面的分佈高度等相關問題進行了理論探討，從理論上證明了魯中期剝夷面難以存在。
  3. Asgis involved many subjects such as computer science, geography and meteorology, gisapplication in geology field is just underway especially in land subsidence research. based on the knowledge and demands above, it is necessary and urgent to establish aspecial gis application system, which is composed of professional base models ( base rockstructural model, structural model of quaternary deposition ) and professional applicationmodels ( groundwater aquifers system structural model, land subsidence forecast andanalysis model ). based on this gis platform, “ management information system of landsubsidence in suxichang area ”, it can deal with and analyze the magnificent multi - originalgeological information visually

    最終研究成果形成了由專業基礎模型和專業應用模型構成的、能對龐大的多源地學信息進行可視化分析處理的綜合應用型gis ，該系統不僅具有一般gis所具有的常用功能，更重要的是可以藉助專業應用模型（如地面沉降相關預測模型）進行計算評價及輔助決策，實現了對蘇錫常地區地面沉降地質災害的科學監測和管理，具有較高的理論意義和應用價值。
