The south part was slope and deep floor of the lake, and the north part was a broad shallow - water platform of the latchstring shore. in the north part, chang - 6 and chang - 7 oil - bearing beds of yanchang formation were typical shallow - water platform delta with an incomplete progradational sequence, in which the delta plain facies were well developed and the river - mouth bars were not developed

The variations in trace element contents and ratios may hold up a mirror to the lake - level fluctuations and climatic changes, which, in turn, have exerted a direct and important effect on the sequence stratigraphic development. collectively, the reservoir rocks from the yanchang formation consist dominantly of the delta front subfacies subaqueous distributary channel and channel - mouth bar microfacies and delta plain subfacies subaerial distributary channel microfacies fine - grained feldspar sandstones and siltstones. the reservoir rocks have been subjected to three stages of diagenetic and porosity evolution : ( 1 ) the porosity reduction by the mechanical compaction and chemical pressure solution during the early diagenetic stage ; ( 2 ) the porosity increase by the dissolution during the a substage of the late diagenetic stage, and ( 3 ) the porosity reduction by the cementation and filling during the b substage of the late diagenetic stage
系統的儲層特徵研究表明，該區延長組儲層成因類型主要為三角洲前緣水下分流河道、河口砂壩及三角洲平原水上分流河道微相細粒長石砂巖、粉砂巖；儲層巖石經歷了壓實，膠結，溶蝕等成巖作用，歷經早成巖機械壓實和化學壓溶孔隙縮小期、晚成巖a亞期溶蝕作用孔隙擴大期及晚成巖a亞期（ b亞期）膠結充填孔隙縮小期三個成巖-孔隙演化階段；儲層物性總體上具有較低孔滲、低孔滲的特點，孔隙類型主要為粒間溶孔、殘余粒間孔隙、粒內溶孔、晶間孔及晶間溶孔，裂縫不發育，儲集巖排驅壓力和中值壓力較高，孔隙結構類型以細小孔-微孔隙，微細喉-微喉型為主。 -

Successfully applied markov process to analyze the change of vegetation cover, and point out the change of vegetation transition is not a single markov process but a multi - markov process and also is a long term process. 9. the writer proved that under the 8km resolution, the markov process ca n ' t estimate the trend of land use by two term - data no matter it ' s sequence or at intervals. through analyzing the change of each vegetation area, the change of spatial data and the markov process, the main conclusions are : in plain of china western arid land, the desert area decreased and the oasis area increased, most of the increase represents extension of the traditional oasis
利用回歸方程對今後的植被變化情況進行了模擬預測，其結果具有一定的參考價值；南京氣象學院博士學位論文8 .將馬爾科夫過程成功地應用於中國西部干早區的植被變化分析當中，指出，植被的轉移變化不是一重馬爾科夫過程，而是一個多重的馬爾科夫過程;而且是一個步長較長的馬爾科夫過程; 9 .證明在8klll尺度下，馬爾科夫過程不能使用兩期的土地利用變化來預測土地利用的發展趨勢，無論這兩期的時間是連續的還是有一定時間間隔的;通過各類植被的面積變化、空間變化及馬爾科夫過程分析認為:中國西部乾旱區在平原區整體上荒漠面積減少，綠洲面積增加，綠洲的面積擴大主要表現在原有綠洲的擴大。 -
