ABSTRACT Past human land-use is increasingly recognized as a driver of ecosystem change in seemingly natural landscapes. Quantification of historical land use is therefore critical for assessing the degree of human impact and requires integration of geography, ecology and history. This paper examines the impact of climate change, land-use and exposure to international markets on the terrestrial ecology in Suðursveit, in southeast Iceland between AD 1700 and 1901. For this we use historical data concerning land-use, livestock and demography, and mapping of glacier advance, glacier outburst floods (jökulhlaups) and agricultural land. Change in land-use or population during the eighteenth century was insignificant. Population declined in the first two decades of the nineteenth century due to the advance of Breiðamerkurjökull glacier. After AD 1820, Suðursveit became part of international market for agricultural products, which facilitated population and livestock increase. This led to overgrazing and severe land degradation in the nineteenth century.

公元 1700-1900 年冰岛东南部土地退化中农业和气候的作用

摘要 过去人类的土地利用越来越被认为是看似自然景观中生态系统变化的驱动因素。因此,历史土地利用的量化对于评估人类影响的程度至关重要,并且需要整合地理、生态和历史。本文研究了公元 1700 年至 1901 年间气候变化、土地利用和国际市场对冰岛东南部 Suðursveit 陆地生态的影响。为此,我们使用了有关土地利用、牲畜和人口统计的历史数据以及制图冰川前进、冰川爆发洪水 (jökulhlaups) 和农业用地。十八世纪土地利用或人口的变化是微不足道的。由于 Breiðamerkurjökull 冰川的推进,人口在 19 世纪的前二十年有所下降。公元 1820 年之后,Suðursveit 成为国际农产品市场的一部分,促进了人口和牲畜的增加。这导致了 19 世纪的过度放牧和严重的土地退化。
