Device for simulating climate warming under field conditions

Abstract

The invention relates to a device for simulating climate warming under field conditions. The device comprises an open-top air chamber which is arranged on the field ground, wherein the bottom edge of the open-top air chamber is arranged along the terrain of the field ground, the periphery of the open-top air chamber is closed, the top of the open-top air chamber is breathable, and an air input pipeline is laid in the open-top air chamber along the bottom edge; a temperature feedback control system which comprises a first temperature probe, a second temperature probe and a temperature difference controller, wherein the first temperature probe is arranged inside the open-top gas chamber, the second temperature probe is arranged outside the open-top gas chamber, and the temperature difference controller is connected with the first temperature probe and the second temperature probe; and an air circulation system which is used for inputting air flow into the open-top air chamber through the air input pipeline under the control of the temperature difference controller. The device has the advantages of being lower in construction and maintenance cost, being capable of actively and stably increasing temperature and being higher in precision, and is suitable for the under-forest environment and conducting the simulated temperature increase on the plants in the under-forest environment.

Description

Technical field [0001] The present invention relates to the field of climate change, specifically global warming device for a simulated field conditions. Background technique [0002] Studies estimate of the 21st century the average global surface temperature will rise 0.3 ~ 4.8 ℃, and the temperature is a key factor in the growth and development of biological, severely affected by climate change will have species and whole ecosystems. Global warming and its impact on ecological environment may cause has been taken seriously by Governments and experts and scholars in the world. Recent studies show that climate warming will affect the growth and metabolism of species and developmental growth, causing the loss of biodiversity. It is estimated that each of the six species have a species may be because of the impact of climate change and extinction. Population dynamics and species distribution change caused by global warming will affect the ecosystem, leading to the global ecosystem ...
