中文摘要	通过对运城盆地DXF-S和DXF-N两个全新世典型黄土-土壤剖而磁化率和炭屑浓度的分析,结合已有的研究成果,探讨了该区域野火活动和生态环境演变的基本规律.马兰黄土堆积时期,气候干旱而不稳定,植被呈现荒漠草原或半荒漠草原景观,地方性和区域性野火频繁发生;全新世早期,气候开始由冷干向温湿过渡,但仍比较干旱,野火活动仍然较为频繁,地表植被应为干草原或含有森林成分的干草原景观;全新世中期是全新世最为温暖湿润的时期,野火活动微弱,植被为温带落叶阔叶林为主的森林草原并掺杂少量亚热带植物,但在夏商文化时期,由于人为焚林、围猎、取暖、刀耕火种等生产和生活活动,使野火活动的频率提高,标志着人类开始影响生态环境演变的进程;全新世晚期,气候向干旱化发展,人类生产和生活活动范围的不断扩大,人为野火活动频繁发生,使地表的自然景观逐渐向半自然半人工景观过渡,尤其,近百年以来随着人口的大量增加,聚落规模的迅速扩大,地表已转变为农田景观.
英文摘要	By analyzing magnetic susceptibility and charcoal content at two Holocene loess - paleosol profiles in the Yuncheng Basin and combining with original studied result, the basic laws of wildfire activity and ecological environmental in the area was studied. During the phase of Malan Loess pilling(～11500aB. P.), because of the dry climate and the desolate and boundless grasslands, the local and regional natural wildfire frequently occurred; In the early Holocene (11500 ～ 8500 a B. P.), the local and regional natural wildfire frequently occurred because the climate was still dry although it was becoming wanner and wetter. The vegetation was arid grasslands or arid grasslands including parts of forest; The Holocene Megathermal(8500～3100a B. P.) was the warmest and wettest period during the Holocene, so the wildfire activity was weak. During this period, the main part of forest and grassland was temperate deciduous broad - leaved forest with less subtropical plant. But during the Xia - Shang culture period(3800～3500a B. P. ), the sequence of wildfire activity raised because of human activity such as felling, hunting and farming. It showed that mankind interfered with the evolution of ecological environment. In the late Holocene (3100～0a B. P.), with the increase of climatic aridity and human activity, frequent occurrence of wildfire, the natural landscape gradually became semi -artificial landscape. Especially, with the rapid growth of population and settlement, the natural landscape has entirely become artificial landscape in the recent hundred years.
