| 摘要: |
| 鲁南沿海地区地表约70%以上为中、上更新统及全新统地层所覆盖。其主要成因类型有残积、坡积、冲积、海积以及它们之问的混合类型。第四系总厚度仅有30—40m,地层分布具有明显的东西向的分带性,而南北方向上差异较小。本区古地理的演变过程是:由更新世的陆地环境,经过全新世的海侵,变为现今的滨海环境。古气候则由中更新世的湿热,经过晚更新世的干凉和全新世的温暖期,形成现代温暖的海洋性气候。 |

| QUATERNARY SYSTEM AND ENVIRONMENTAL CHANGES OF PENINSULA COAST IN THE SOUTHERN SHANDONG PROVINCE |

| Abstract: |
| The investigation area with its medium-pleistocene series (Q2), upper-pleistocene series (Q3) and holocene series (Q4) covers an area of more than 70 percent of the southern Shandong province coastal area. Its chief types of origin are sedimentary, slope wash, alluviation, marine accumulation and their mixture. Quaternary system is merely 30-40 mthickness. Distribution of sediment displays an obvious zoning--west to east, but itsdifference is less from north to south. The process of paleogeographic evolution in this area is from land of pleistocene epoch to ingression of holocene epoch, then to littoral circumstances of today. Its paleo-climatological evolution is from humid-hot medium-pleistocene epoch (Q2) to dry-cold upper-pleistocene epoch (Q3), warm holocene epoch and warm maritime climate in recent times. |
