Five pieces of paleogeographic maps were made out with modern stratigraphic principles and sedimantary system method. It is shown by the maps that in the beginning of the Changzhougou time the Yanshan Region was occupied by alluvial environment with paleoriver flowing northeast, in the middle of the Changzhougou time a transgression changed whole Yanshan Region into shoreline-shallow sea environment gradually, and sedimentary boundary extended so continuously that by the Gaoyuzhuang time it had overpassed far beyond the Yanshan Region.

在缺乏良好等时面的情况下，本文依据现代地层学原理和沉积体系分析法编制了常州沟组初期与中期，串岭沟组初期，大红峪组初期，及高于庄组初期燕山地区的岩相古地理图，示意了燕山地区在长城纪时由冲积扇-河流为主的陆地环境向滨海-浅海环境的演变过程，并揭示了沉积区域不断扩大的趋势，表明常州沟组初期，以蓟县-宽城为轴线发育了冲积相组，海岸线可能在燕山以北，常州沟组中期发生海侵，沉积区扩大至整个燕山地区，大红峪组时海盆范围继续扩大，高于庄组时，沉积边界已远远超出燕山地区。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
