氣候要素-
Following the east element, the north temperate elements consist of 53 species corresponding to 29. 94 % of the total. the tropical elements ( including pantropical element, paleotropical element and india - malaysia element ) consist of 38 species sharing 21. 47 % of the total. the results show that the houhe national nature reserve is transitional climatic belt where the tropical and subtropical elements extend northwards and the north temperate elements infiltrate southwards, which accords with its geographical location
本文按現有資料，並參照吳征鎰先生對中國種子植物屬的分佈區類型的劃分，將后河自然保護區蘚類植物劃分為9種成分，其中東亞成分是最豐富的成分，有65種，占總數（扣除世界廣布種，下同）的36 . 72 ，北溫帶成分有53種，佔29 . 94 ，僅次於東亞成分，熱帶成分（包括泛熱帶成分、古熱帶成分和熱帶亞洲）有38種，占總種數的21 . 47 。 -
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。
