 note = {To investigate vegetational change in Upper Pleistocene to Holocene temporal range, lithological analysis, AMS 14C-dating and pollen analysis are conducted for the two cores (SMF-1 and SMF-2) drilled at the southeast side of Maeda Forest Park in the northern part of Teine-ku, Sapporo City, Hokkaido, Japan. The distance between the two cores is only 15 m and core lengths are about 41-44 m. The facies of the upper and lower sediments change clearly at the depth of 28 m. The upper section from the ground level to 28.0 m of the SMF-1 core (44.45 m in length) is an alluvial bed (Chuseki-so) consists of main sandy layer and lower muddy layer. AMS 14C age of 10,800-10,400 cal.yBP (91.7%) was obtained for a peat sample collected at 26.55 m in depth from the basal part of the lower muddy part. A pollen analysis suggests that the layer from 26.55 to 28.0 m belongs to a cool zone (SMF1-D) rich in Picea, and can be assigned as the Younger Dryas period. The lower section from 28.0 m to 36.05 m is considered as the stratum MIS 3 in Late Pleistocene, because 14C age of 43,300-42,400 cal.yBP (95.4%) is obtained for a peat sample collected at 31.5 m in this section. This is consistent with vegetational zoning based on pollen and spore (SMF1-A, B and C zones). It is also evident that the stratum of Last Glacial Maximum (MIS 2) is missing in SMF1 core that should be at above 28.0 m in depth if it exists., 札幌市手稲区北部の前田森林公園南東側で掘削されたSMF-1孔（標高5.5m），SMF-2（標高5.61m）のコアを利用してコア層相解析，AMS14C年代測定および花粉分析による研究を行った．両孔は約15mの間隔で近接しているが，両孔では深度28m（標高-22.5m）付近を境にして，沖積層とその下位の地層に分けられ，下位の地層は上部更新統で，上部層は小野幌層，下部はもみじ台層に対比できる．2つのコアの花粉分帯は統合的にとらえると，下位よりSMF1-A帯（SMF2-A帯），SMF1-B帯（SMF2-B帯），SMF1-C帯（SMF2-C帯+SMF2-D帯），SMF1-D帯およびSMF1-E帯（SMF2-E帯）に区分できる．これらのうち，沖積層の最下部を占めるSMF1-D帯はSFM-1孔の深度26.55mで10,800-10,400cal.yBP(91.7%)のAMS14C年代値が得られており，その下位に当たることから，ヤンガードリアス期の可能性がある．下位の地層のうち，SMF1-B帯+SMF1-C帯（SMF2-B帯+SMF2-C帯+SMF2-D帯）は深度31.50mで43,300-42,400cal.yBPのAMS14C年代値が得られており最終氷期MIS3と見なされる．沖積層と下位層の間は顕著な不整合で，最終氷期最寒冷期（MIS2）は欠如していることが明らかである．},
