中文摘要: |
对福建晋江海岸风沙集中分布区深沪镇海岸带颜厝(YC)剖面进行了粒度参数、成因判
别分析. 在此基础上,划分出YC 剖面的敏感组分作为指示风动力变化的代用指标,将其与前人同期
的地质记录以及东亚晚全新世环境的相关研究进行对比,初步确定了福建东南沿海近1000 a 来海
岸沙丘记录的环境演变,结果表明:(1)1180 - 1320 A.D.,冬季风由弱变强,气候从湿热转向干冷;
(2)1320 - 1800 A.D.,冬季风较强,东南沿海进入小冰期,表现为干冷的气候环境;(3)1800 - 2000
A.D.,冬季风由强转弱,由小冰期进入现代暖期,气候逐渐由冷干向暖湿过度. |

This paper analyse granularity parameters and discriminant of the Yancuo section(YC)in the sand concentra⁃
tion distribution area Shenhu town coastal zone of the coast of Jinjiang in Fujian province. On this basis, differentiate the
sensitive components of YC profile for the surrogate indicator for wind power change, compare it with the geological records
of the same period and the related research of east Asia late holocene environment. Results show:(1)1180-1320 A.D., the
winter monsoon from weak to strong, climate from humid to dry cleaning.(2)1320-1800 A.D., Winter monsoon is stronger,
southeast coast into the little ice age, performance for the dry and cold climate environment.(3)1800-2000 A.D., Winter
wind from strong to weak, the climate from the little ice age to modern warm period, gradually by excessive person and
warm to wet and warm. |
