data research

In parks, there is a significant correlation between the diversity of plant species and their distance from the water body. I observed that the plants that grew near the water body were significantly more abundant, and that the plants grew more luxuriant and healthy. Specifically, as the distance between plants and water gradually shortens, the number of plant species is gradually increasing. This may be because the water body provides the plants with sufficient water and moist soil environment, which promotes the growth and reproduction of more plant species. In addition, microclimate conditions around water bodies may also be more suitable for plant growth, such as higher air humidity and lower temperature fluctuations, which work together make the area close to water bodies hot spots for plant diversity. . Based on this observation, I propose the following hypothesis that there is a significant positive relationship between plant species diversity and water distance in parks. To test this hypothesis, I plan a field visit with specific steps as follows: First, I will select a park with different distribution of water bodies as the research object. In the park, choose the same size sample square, but the distance from the water body is different. For example, you can set samples at different distances of 0 and 10 meters, 10 and 10 and 20 meters, and 20 and 30 meters from the water body. Next, I will conduct a detailed plant investigation within each square. The survey included recording data on the species, number, height and coverage of all plants in the sample square. In addition, I will record environmental factors such as soil humidity and light intensity in the sample to exclude other factors that may affect plant diversity. I will compare the number of plant species and their growth status in the relationship between plant species diversity and water distance. If I find more plant species and better growth status in the quadrat closer to the water body, then this would support my hypothesis. Finally, to further test this hypothesis, I will also conduct some experiments. For example, I can artificially increase the soil moisture in a sample square far away from the water body to see if it can promote the increase of plant species and improve the growth status. Through these experiments, I can more accurately judge the effect of water body distance on plant diversity.
