Grimm and Christian studied 70 terms and 163 completely different definitions of ecosystem stability from different angles and concluded that ecosystem stability can be summarized in the following three basic characteristics: remaining unchanged, restoration to a state close to the original state. state after a temporary disturbance (the original text is a reference state, which can be poorly translated), and the continuity of the ecosystem over time. Although resistance is often considered a separate concept from resilience, Brian Walker and colleagues view resistance as a component of resilience broadly, describing the definition of resilience as "very close to the concept of 'toughness'" . Therefore, it is normal for you to be confused about the relationship between the two, and it is not just your own strange thoughts. Because ecological phenomena are too complexlexes, the same phenomenon can be defined differently from different perspectives, and the same phenomenon can be caused by different causes in different environments. I'm also perplexed by the negative correlation between the two. In the English information, I only found one place where it was mentioned that resistance and resilience were negatively correlated. But this relationship is at the level of individual species and not at the level of ecosystems. Later, in order to research how this point was mentioned in textbooks, I found this paragraph on Baidu Encyclopedia: "For another example, after a fire broke out in a grassland, dense herbaceous plants grew back the following year, and the types and quantities of animals It can also recover quickly. For an ecosystem, there is often an inverse relationship between the stability of resistance and the stability of resilience. EcosystemsSystems with higher resilience stability have lower resilience stability, and vice versa. The stability of the forest ecosystem is higher than that of the grassland ecosystem, but its resilience stability is much lower than that of the grassland ecosystem. Once the tropical rainforest is severely damaged (such as deforestation), it is very difficult to restore it to its original state.
It's safe. The natural environment itself has a self-adjusting function. Today, due to human overproduction and emissions, it has far exceeded the self-regulating state of nature. , this is why we have current environmental problems such as air pollution and the greenhouse effect.
If there were no human production activities, that is to say there would be no sources of pollution. Nature's current adjustment capacity, existing pollution will gradually be digestedreal, but the time will certainly be relatively long. There must be professional organizations in this regard that can calculate the specific time, but it can certainly be digested by nature. >
It is therefore impossible for humans to stop production activities, but we must take more care of the environment on which we depend and eliminate behaviors that pollute the environment.
