做一场实验的难度,不光体现在具体的实验对象上,变幻莫测的外部环境,常使野外实验进展得十分艰难。比如,我们的烟圈大炮实验就差点因环境原因告吹!环境清幽的德国施特希林湖,生态学会研究者创造了一个可随意操纵的野外环境,来进行各种可控实验:24个直径9米,深20米且直插湖底的塑料围墙,分隔出24个微型湖泊,每个“水中实验室”囊括各种藻类和水生植物,科学家只需调整微型湖泊的水温分布,便可研究气候变化对淡水生态系统的影响啦!
The difficulty of doing an experiment, not only reflected in the specific experimental subjects, unpredictable external environment, often make the field experiment progress very difficult. For example, our experiments with smoke and cannon almost came to an end due to environmental reasons! In a quiet environment in Stechlinsee, Germany, the Institute of Ecology researchers created a freely manipulated field environment for a variety of controlled experiments: 24 diameter 9 Meters, 20 meters deep and inserted directly into the plastic wall at the bottom of the lake, separating 24 miniature lakes, each “Aquatic Laboratory” includes a variety of algae and aquatic plants, scientists can adjust the temperature distribution of micro-lakes can be studied Impact of climate change on freshwater ecosystems it!
