（2）由于研究时间较短，导致了实验结果不够严谨，pM2.5对于植物气孔

(2) Due to the short research time, the experimental results are not rigorous enough. The effect of pM2.5 on plant stomata is a long-term process. Our 30-day study is only a small part of this long process. The small amount of data and the short monitoring time result in relatively large data fluctuations, and there is no obvious trend or law. <br>(3) In addition to pM2.5, stomata are also very sensitive to other environmental factors, such as light, moisture, ambient temperature, etc. The stomatal index data obtained from the herbarium is affected by the change of pM2.5 caused by human activities In addition, other global climate change factors, such as temperature, may also work simultaneously with [pM2.5]. Similarly, the stomatal index obtained from fossil plants may also be affected by other environmental factors besides pM2.5, especially temperature fluctuations. Therefore, it is important to distinguish whether there are factors that have a greater impact on the stomatal index than the change of pM2.5, especially whether the effect of temperature increase will exceed the effect of increasing pM2.5. This is useful for studying the effect of stomatal index on pM2.5. Response is crucial. <br>(4) In addition, the selection of plants is also an important factor. Some researchers have observed 10 kinds of plants and found that different plant stomatal indexes respond differently to pM2.5. Therefore, the selection of plants is also something we need to discuss One of the factors. <br>Therefore, in the follow-up research, this research will be continued and continuously improved to increase the rigor of the experiment, in order to confirm the correctness and rationality of the results obtained.

(2) Due to the short research time, resulting in less rigorous experimental results, pM2.5 for plant pores is a long-term process, our 30-day study is only a small part of this long process, so due to the small amount of data and less monitoring time, resulting in relatively large data fluctuations, there is no obvious trend or law.<br>(3) In addition to pM2.5, pores are also sensitive to other environmental factors, such as light, moisture, ambient temperature, etc., the pore index data obtained from the specimen museum, in addition to being affected by changes in pM2.5 caused by human activities, other global climate change factors, such as temperature, may also play a role in conjunction with the pM2.5. Similarly, pore indices obtained from fossil plants may be affected by environmental factors other than pM2.5, in particular temperature fluctuations. Therefore, it is important to study the response of pore index to pM2.5 to distinguish between factors that have a greater effect on the change of pM2.5 than the change of pM2.5, especially whether the effect of temperature increase exceeds the effect of pM2.5.<br>(4) In addition, plant selection is also an important factor, some researchers observed 10 kinds of plants, found that different plant pore index response to pM2.5 is not the same, so the choice of plants is also one of the factors we want to explore.<br>Therefore, in the follow-up study, the study will continue and continue to improve to increase the rigour of the experiment, in order to confirm the accuracy and rationality of the results.

（2）由于研究时间较短，导致了实验结果不够严谨，pM2.5对于植物气孔的影响是一个长期的过程，我们为期30天的研究仅仅是这个漫长过程的一个很小的部分，因此由于数据量少以及监测时间较少，导致数据波动比较大，没有明显的趋势或规律。（3）除了pM2.5外，气孔对于其他环境因子也很敏感，如光照、水分、环境温度等 从标本馆所得到的气孔指数数据，除了受到由于人类活动所引起的pM2.5的改变影响外，其他全球气候变化因素，如温度，也可能与 [pM2.5 ]同时起作用。同样，从化石植物得到的气孔指数也可能受到除pM2.5以外的其他环境因素特别是温度波动的影响。因此区分在对气孔指数诸多影响因素中，是否有比pM2.5变化影响更大的因素，尤其是温度升高的作用是否会超过pM2.5增加的作用，对于研究气孔指数对pM2.5的响应是至关重要的。（4）此外，植物的选取也是一个重要因素，有研究者对10种植物进行观测，发现不同植物气孔指数对pM2.5的响应程度是不一样的，因此在植物的选择也是我们要探讨的因素之一。因此在后续的研究中，会将本研究持续进行下去并进行不断改进增加实验严谨性，以期确认所得结果的正确性与合理性。<br>
