摘要

本文利用全球导航卫星系统技术,确定了欧亚河狸(Castor fiber L.)在俄罗斯欧洲伏尔加-卡马地区十条河流沿岸所建水坝和池塘的分布特征和一些形态计量参数。探测到的特征取决于这些河流及其流域的地貌、岩性和景观特征。河坡以及地貌分区在研究地区小河沿岸海狸坝和池塘的分布中起着重要作用。在所研究的河流中,几乎所有的海狸坝都位于河床坡度小于 3% 的地方(最常见的是小于 2%)。在森林区南部(维亚特卡河流域的南部泰加林区),大多数水坝和池塘(约 90%)都位于坡度小于 1%的斜坡上,而在森林草原区的高地上,坡度因河流长度而异。一般来说,在其他条件相同的情况下,河流的平均坡度越大(流域的平均海拔越高),海狸对这些河流的改造程度就越低。这一特征在森林景观带的河流中表现得更为明显,而在流经森林草原地带的河流中则表现得较少。对海狸坝形态参数的分析表明,随着河道坡度的增加,海狸坝的平均高度也呈显著增加趋势。此外,随着河道坡度的增加,海狸坝的长度和相关池塘的长度也呈明显的减少趋势。值得注意的是,这些参数在统计意义上发生显著和相对急剧变化的坡度临界值分别为 1.45%、1.07(或 0.54)% 和 0.65(或 0.47)%。与 "沙质 "河流流域相比,海狸坝的最大平均高度仅限于那些流域由黄土岩石/土壤(尤其是那些耕作条件较差的河流)构成的河流。这可能是由于这些流域地表水和地下水径流比例的特殊性,以及由融雪和降雨引起的洪水流量强度的不同。我们认为,上述特征反映了海狸在所研究河流中扩张(数量增长)的早期阶段。

Features of the Distribution of Beaver Dams and Ponds along Small Rivers: The Volga-Kama Region, European Russia
In this paper, by using GNSS technologies, some features of the distribution and some morphometric parameters of dams and ponds created by the Eurasian beaver (Castor fiber L.) along ten rivers of the Volga-Kama region of European Russia were identified. Detected features depend on the geomorphological, lithological, and landscape features of these rivers and their basins. The significant role of river slopes, as well as landscape zoning, in the distribution of beaver dams and ponds along small rivers in the study region is shown. In the rivers under study, almost all beaver constructions are located on riverbed slopes of less than 3% (most often, less than 2%). In the south of the forest zone (the southern taiga of the Vyatka River basin), the majority of dams and ponds (about 90%) are located on slopes of less than 1%, while, within the uplands of the forest-steppe zone, this location varies depending on the length of the rivers. In general, the greater the average slope of the river (the greater the average elevation of the river basin), the lower, other things being equal, the degree of beaver transformation of such rivers. This feature is better expressed in the rivers of the forest landscape zone and less expressed in the rivers flowing in the forest-steppe zone. Analysis of the morphometric parameters of beaver dams shows statistically significant trends towards an increase in their average height, as the channel slopes increase. Statistically significant trends were also identified towards a decrease in the length of dams and the length of associated ponds, with an increase in channel slopes. It is noteworthy that the critical values of the slope for a statistically significant and relatively sharp change in these parameters are 1.45%, 1.07 (or 0.54)%, and 0.65 (or 0.47)%, respectively. The greatest average heights of beaver dams are confined to those rivers where their basins are composed of loamy rocks/soils (especially those that are poorly plowed), compared with “sandy” river basins. This may be due to the peculiarities of the ratio of surface and underground water runoff in these basins and, as a consequence, different intensities of snowmelt- and rainfall-induced flood flow. We assume that the above-mentioned features reflect the early stages of beaver expansion (population growth) in the studied rivers.
