【期刊论文】The surface pollen of the woodland–steppe ecotone in southeastern Inner Mongolia, China

Review of Palaeobotany and Palynology 105(1999)237~250,-0001,():

Surface pollen deposition in a modern woodland–steppe ecotone in the southeastern edge of the Inner Mongolia Plateau, situated between the deciduous broadleaved forest zone and the steppe zone in Asia, has been investigated. The following pollen and spore groups can be classified according to the relationship between surface pollen and plant community: (1) pollen group representing the whole study region: Artemisia, Betula, Chenopodiaceae, Polygonaceae and Plantago; (2) pollen group representing a vegetation zone: Pinus; (3) pollen and spore group representing a certain community type: Quercus, Picea, Ostryopsis, Corylus and spores; and (4) pollen group having a low representation: Ulmus, Gramineae, Leguminosae and Compositae. According to the pollen composition in each vegetation zone, four vegetation zones of the investigated area could be characterized by the following combinations of pollen types: (1) woodland zone: Betula–Pinus-Artemisia; (2) woodland–grassland zone: Betula-Artemisia; (3) woodland-steppe zone: Artemisia-Betula-Chenopodiaceae; and (4) steppe zone: Artemisia-Chenopodiaceae. Some ratios of various pollen types have been proved to be better at indicating the vegetation gradient than single pollen types. For example, C=A (Chenopodiaceae=Artemisia), A=B (Artemisia=Betula) and AP=NAP (Arboreal pollen=Non-Arboreal Pollen) show distinctly the gradient from the woodland zone to the steppe zone. This investigation has a future application for the reconstruction of Holocene vegetation and climate history in the investigated area. Various pollen combinations can be used as 'indicator units' for the diagnosis of vegetation types from fossil pollen analysis. Some problems of the interpolation of vegetation from fossil pollen data in the semi-arid area have also been discussed. High Artemisia pollen value do not indicate an Artemisia-dominated steppe vegetation due to the under-representation of Gramineae pollen. Plantago pollen in semi-arid and arid area can hardly be regarded as an indicator of human interference.

【期刊论文】The origin of remnant forest stands of Pinus tabulaeformis in southeastern Inner Mongolia
刘鸿雁, Hongyan Liu, Haiting Cui, Pengtao Yu, & Yongmei Huang

Pinus tabulaeformis is an endemic species in northern China. The northern edge of its distribution corresponds to the northern margin of the monsoon climate. Several stands of Pinus tabulaeformis beyond its major range of distribution were found on the southeastern edge of the Inner Mongolia Plateau. Phytosociological analysis shows that the community structure, species composition and regeneration ability of Pinus trees in these stands are quite different from those within its continuous range of distribution. This paper presents palynological evidence to explain how and when these remnant communities were formed. Pinus tabulaeformis entered the study area in the mid-Holocene as the summer monsoon intensified, and declined when the summer monsoon weakened. Climatic change was the driving factor for the migration of Pinus tabulaeformis. It might be supposed that the competition between pine and oak forest during the mid-Holocene warm period also affected the immigration of pine. The remnant stands of Pinus tabulaeformis were apparently favored by the microhabitat of the sandy soils in valleys when the climate became drier. The remnant stands of Pinus tabulaeformis help stabilize the stand dunes. The protection of these stands is an important task of natural conservation in the study area.

Discriminant functions link vegetation zones and surface pollen along the woodlandsteppe ecotone in northern China. These links were utilised to reconstruct palaeovegetation using fossil pollen data from four lake sediment sites within the ecotone. Holocene movements of the vegetation zones were derived from the above results and were interpreted as the results of climatic, topographic and edaphic factors. This study shows that climatic change was the driving factor for ecotonal movement, but that the positions of vegetational zones were nevertheless controlled by topographical and edaphic conditions, and consequently boundaries between different vegetational zones responded individualistically.

内蒙古高原东南部森林草原过渡带位于中国东部季风气候尾间区,是全球变化研究的关键区域。这一地区降水量存在着明显的东南至西北(SE-NW)梯度。在现代植被和表土花粉分析的基础上,建立了内蒙古高原东南缘森林草原过渡带孢粉一降水量转换函数。将研究区森林草原过渡带内3个湖泊沉积剖面的孢粉分析结果代入转换函数,定量恢复了这一地区全新世降水量的变化过程。结果表明:3个剖面全新世以来降水量变化的过程存在明显的差异,北部的好鲁库剖面在l 100a BP以前一直呈减弱的趋势,而南部的碌轴湾剖面和小牛场剖面降水量在分别在7800-6200a BP和7200-5000a BP出现降水量的峰值,作者推断这种时空差异性与西南季风的影响、地形条件的差异有关。

Different land cover types in Otindag Sandy Land and Bashang area of Hebei Province are linked to a material source of sand stormy weather in Beijing based on results of field vegetation and soil survey and laboratory works. Results of grain size analysis show that dust release potential in per unit area of moving sandy land is small, while lowland meadow and meadow steppe in stony hills have high potential of releasing dusts in per unit area during sand stormy weather occurrence. Further considering the effects of vegetation, it is inferred that the moving sandy land served as a material source of past dust storm and the possibility of dust release in per unit area is low in current time. Typical steppe in stony hills is undergoing desertification and its dust release possibility in per unit area is high. Farmland has strong potential of release dusts when they are ploughed in spring, but a large amount of therophytes grow and thus prevent dusts from release when cultivation was terminated. Potentials of dust release in per unit area in fixed sand dunes, stony mountain meadow steppe and lowland meadow are low due to high cover of perennials. Sand dune reactivation and desiccation of lakes and lowlands under estimated future climatic change will make them serve as a future material source of sand stormy weather.

Anxi County is located in the northweslem part of the Hexi Corridor in Gansu Province and has the sole national level nature reserve of extremely-arid desert in China. Phylosoeiological rnetheds (Braun-Blanquet, 1964) are used to classify plant community types in this area. Eleven are distinguished, ineluding sis of deserts, four of iases and one transitional type between deserts and oases, Direcl gradient analysis (DCA) is employed to correlate the distribution of plant communities to physiogegraphie conditions. This study makes clear that water is the most important ecological factir. for the distribution of plant species and communities in this area. The effects of water have been demooatrated in different ways. Avegetation gradient from lower altitude to higher altitude in the southecn part of the reserve is driven by a precipitation gradient. The effeets of the depth of grmund water table contribute to the differentiation of vegetation from desert to oasis in the flat area. In a finer seale, the washexl gullies have obviously higher species richnesa and also higher vegetation cover than the surround gobi surfaces, passibly caused by the effects of floods. The vegetation patterns demonstrate that the area of Anxi, County is a complete landscape unit. The rangu of the current natture rrserve is not largu enough for the purpose of conserving the unique biodiversity, in this area.

【期刊论文】Holocene History of Desertification along the Woodland-Steppe Border in Northern China

The woodland-steppe ecotone of the southeastern Inner Mongolian Plateau in northern China is located at the northwestern limit of the Pacific monsoon influence, where the landscape may have been a sensitive recorder of past climatic changes. Physical, chemical, and biological analyses of AMS 14C-dated sediment sequences from two lakes of this region were used to reconstruct the Holocene vegetation and desertification history and distinguish four periods: (1) a cold and humid period from 10000 to 8000 14C yr B.P., (2) a warm and humid period from 8000 to 5900 14C yr B.P., (3) a warm and dry period from 5900 to 2900 14C yr B.P., and (4) a cool and dry period from 2900 14C yr B.P. to the present. The increased aridity during the middle Holocene was likely caused by increased winter temperatures and enhanced winter evaporation. The transition from a humid to an arid climate after 5900 14C yr B.P. coincided with enhanced aeolian activity, and deciduous woodlands were replaced by pine woodlands and then by steppes in response to the climatic deterioration. These transitions led to the present desertification. The records suggest that a simple association of thermal and moisture conditions, such as warm/wet or cold/dry, may be misleading.

Mineral magnetic properties (SIRM, ARM, HIRM and S-ratios) are presented for two AMS 14C-dated pit-sequences of lake sediments recovered from Haoluku and Liuzhouwan (~43 N, 117 E). The two sites fall in the semi-humid to semi-arid climate transition zone, Dali Nor area of the southeast Inner Mongolia Plateau, China. Complemented by data for loss-on-ignition (LOI), total organic carbon (TOC), carbon/nitrogen (C/N), grain-size, and pollen, these mineral-magnetic measurements provide additional insights into environmental changes occurring at this area over the last 13 500 years. Conditions were extremely dry and windy as shown by the low SIRM, ARM and HIRM and high S-ratios before 13 500 yr BP. The environment began to ameliorate gradually since then, and a further humidification occurred at~10 300 yr BP in Haoluku, the northern site, and at -9400 yr BP in Liuzhouwan, the southern one, as implied by the increased but only moderately high SIRM, ARM and HIRM and decreased S-ratios. As indicated by the remarkably increased SIRM, ARM, HIRM and S-ratios, a deterioration commenced at ~5600 yr BP in Haoluku and at ~4700 yr BP in Liuzhouwan. In Haoluku, conditions have been generally dry and windy since ~5600 yr BP despite a minor amelioration at 4500-3000 yr BP. A short but marked amelioration occurred at 1200-700 yr BP in Liuzhouwan. S-ratios seem to be a reliable indicator of environmental aridity for this area. ~ 2001 Elsevier Science B.V. All rights reserved.
