中文摘要:

花粉分析是为古植物学和古气候的量的重建的最好、可能的途径之一,并且人的活动的辨别。在这份报纸,我们在人的影响是严肃的 Anyang 区域以不同农业单位和他们主要花粉 taxa 的空间分发揭示花粉集合的特征,以便从花粉记录关于气候变化和人的活动得到更多的信息。总数 122 表面的花粉集合从不同农业单位玷污样品(农场陆地,蔬菜阴谋,荒地,披肩陆地,树林,等等) 显示那草本的花粉与 73% 的一般水准统治花粉集合主要从 Poaceae, Artemisia, Chenopodiaceae 和十字花科;树木的花粉百分比到达 18% ,主要从 Pinus 和 Ulmus;灌木花粉和蕨纲植物孢子有很低的百分比。一般来说,花粉集合与植被作文一致,尽管一些差别也以不同农业单位存在。在农田和蔬菜陆地, Poaceae 花粉有最高的百分比(平均 27%) 与有主导的玉米或小麦花粉的另外的农业单位相比在荒地和树林,树木并且 Artemisia 花粉百分比有更高的价值(分别地平均 20% 和 19%) 。十字花科在强奸陆地有最高的花粉百分比(70%) 。花粉集合和 PCoA 罐头通常识别蔬菜阴谋,农田,树林,荒地,和强奸陆地。Pinus 和 Artemisia 花粉主要出现在 Anyang 的西方的部分,它与父母植物一致;Poaceae 花粉主要与更多的农田在东方部分存在;Chenopodiaceae 花粉主要出现在城市的区域和人的影响更强烈的近主要的道路,十字花科花粉能主要在城市的区域并且在更多的蔬菜被种的 Anyang 的西北部分被发现。

英文摘要:

Pollen analysis is one of the best and possible approaches for the quantitative reconstruction of paleobotany and paleoclimate, and discrimination of human activities. In this paper, we reveal the characteristics of pollen assemblages in different agricultural units and their spatial distribution of major pollen taxa in the Anyang area where the human influences are serious, so as to get more information about climate change and human activities from pollen records. The pollen assemblages of total 122 surface soil sampies from different agricultural units (farm lands, vegetable plots, wastelands, cape-lands, woodlands, etc.) indicate that herbaceous pollen dominates the pollen assemblages with an average of 73%, mainly from Poaeeae, Artemisia, Chenopodiaceae and Cruciferae; arboreal pollen percentages reach 18%, mainly from Pinus and Ulmus; shrub pollen and fern spores have very low percentages. In general, pollen assemblages are consistent with vegetation composition, though some differences also exist in different agricultural units. In farmlands and vegetable lands, Poaceae pollen has the highest percentages (averaging 27%) compared to other agricultural units with dominant corn or wheat pollen, while in wastelands and woodlands, arboreal and Artemisia pollen percentages have higher values (averaging 20% and 19% respectively). Cruciferae has the highest pollen percentages (70%) in rape-lands. Both pollen assemblages and PCoA can generally identify the vegetable plots, farmlands, woodlands, wastelands, and rape-lands. Pinus and Artemisia pollens mainly appear in the western part of Anyang, which is consistent with the parent plants; Poaceae pollen mainly exist in the eastern part with more farmlands; Chenopodiaceae pollen mainly appear in the urban areas and near major roads where human influences are stronger, Cruciferae pollen can mainly be found in the urban area and in the northwest part of Anyang where more vegetables are planted.
