中文摘要：

从在东北中国的农田和荒地的 53 件表面花粉样品的花粉集合被分析。树花粉百分比通常比30%高，与 Pinus (26.9%)， Quercus (0.9%)， Betula (0.9%)和象主要类型的 Populus (0.7%)，和植物花粉百分比通常比50%高与蔓延的 Poaceae (8.7%)， Chenopodiaceae (7.1%)， Artemisia (1.9%)和 Compositae (3.5%)作为主要 taxa 。因此，花粉集合与地区性的植被作文一致。然而，在在区域之中的花粉集合有差别，特别在不同 geomorphological 单位之中。例如在山，比在另外的区域有树花粉和更高全部的百分比(一般水准 42%) 的更多的类型，当谷物花粉百分比最低时(11.2%) 。在山和高平原，植物完成了超过 60% 花粉，与谷物(一般水准 53.6%) 主导的类型。在低平原，花粉类型类似于在山和高平原的那些，但是全部的花粉集中和 Concentricystes 的比例高得多，当谷物花粉百分比稍微更低时(一般水准 41.6%) 。在不同陆地使用类型的花粉集合也不同。例如在农田，谷物花粉百分比是超过 40% ，， Chenopodiaceae 通常在荒地是不到 2.5% ，蔓延的 Poaceae 通常是不到 10% ， Chenopodiaceae 通常比 25% 高。在农田(一般水准 3909 grains/g ) 的全部的花粉集中比在荒地(一般水准 15074 grains/g ) 低得多。冗余性分析表明花粉集合否定地显著地与吝啬的年度温度(0.73 ) 和 7 月吝啬的温度(0.81 ) 被相关并且断然显著地与吝啬的年度降水(0.48 ) 相关，显示在人工或扰乱人的植被的花粉集合反映地区性的气候很好。

英文摘要：

Pollen assemblages of 53 surface pollen samples from farmlands and wastelands in Northeast China were analyzed. Tree pollen percentages were usually higher than 30%, with Pinus （26.9%）, Quercus （0.9%）, Betula （0.9%） and Populus （0.7%） as the major types, and herb pollen percentages were usually higher than 50%, with weedy Poaceae （8.7%）, Chenopodiaceae （7.1%）, Artemisia （1.9%） and Compositae （3.5%） as the major taxa. Thus, the pollen assemblages were consistent with the regional vegetation compositions. However, there were differences in pollen assemblages among regions, especially among different geomorphologi- cal units. For example, in the mountains, there were more types of tree pollen and higher total percentages （average 42%） than in other areas, while cereal pollen percentages were lowest （11.2%）. In the hills and high plains, herbs made up more than 60% of the pollens, with cereals （average 53.6%） the dominant type. In the low plains, pollen types were similar to those in the hills and high plains, but total pollen concentrations and the proportion of Concentricystes were much higher, while cereal pollen percent- ages were slightly lower （average 41.6%）. Pollen assemblages in different land use types also differed. For example, in farmland, cereal pollen percentages were more than 40% and Chenopodiaceae was usually less than 2.5%, while in wasteland, weedy Po- aceae was usually less than 10% and Chenopodiaceae was usually higher than 25%. Total pollen concentrations in farmland （av- erage 3909 grains/g） were much lower than in wasteland （average 15074 grains/g）. Redundancy analysis revealed that pollen as- semblages were significantly negatively correlated with mean annual temperature （-0.73） and July mean temperature （-0.81） and significantly positively correlated with mean annual precipitation （0.48）, indicating that pollen assemblages in the artificial or human-disturbed vegetation reflect regional climate well.
