Abstract

At low latitudes (i.e., in the equatorial zone), the primary production of lake ecosystems is comparable with the plant production in their water catchment areas. In contrast, at high latitudes, the primary production of lake ecosystems is less than the primary terrestrial production approximately by two orders of magnitude. This paper addresses the reason behind the different reactions of the terrestrial and lake ecosystems to external factors determined by the geographical zone. Computational experiments show that in accordance with van’t Hoff’s rule, at high latitudes featuring low temperatures and higher humidity, the plant matter decomposition rates in lake basins are lower in comparison with low latitudes. The lower decomposition rates slow down the release and outflow into the water of nutrients essential for the organic matter production by aquatic autotrophs.

湖泊和陆地生态系统初级生产值之间的比率。

摘要

在低纬度(即在赤道带),湖泊生态系统的初级产量与集水区的植物产量相当。相反,在高纬度地区,湖泊生态系统的初级生产力要比陆地初级生产力低大约两个数量级。本文讨论了陆地和湖泊生态系统对地理区域确定的外部因素的不同反应背后的原因。计算实验表明,按照范霍夫定律,在高低温低湿的高纬度地区,与低纬度地区相比,湖盆中的植物分解速率较低。
