The greenhouse effect caused by human activities leads to global warming, and the impact of climate warming on the global ecological environment has attracted more and more attention.
Attention. As the main body of the environment on which human beings depend, what kind of response the terrestrial ecosystem will make to climate warming is the focus of people's attention. plant
Phenological changes can directly reflect some climate changes, especially climate warming. Climate warming affects the growth rhythm of plants, which in turn leads to plants.
Changes in the relationship with the environment and changes in the material cycle of the ecosystem (such as water cycle and carbon cycle). Different kinds of plants have different responses to climate change.
The competition and dependence between plants, animals and plants have undergone profound changes, such as the extension of vegetation growth season and the advance of plants in the middle and high latitudes of the northern hemisphere.
Flowering, insects appear early, birds lay eggs early, glaciers retreat, frozen soil melts, and rivers and lakes freeze and melt early. Main text
We should focus on the distribution and succession of terrestrial ecosystems, and systematically discuss forests, grasslands, deserts and wetlands with plants and animals as the objects of investigation.
And the changes of terrestrial ecosystems such as farmland under the background of climate warming, and put forward the ecology of terrestrial ecosystem changes from micro and macro scales.
Finally, some countermeasures are given from the technical and policy levels.
Climate warming, distribution and succession mechanism of terrestrial ecosystem, countermeasures
