The researchers studied the differences in plants and soil in an oasis-desert area. They found that vegetation and soil factors varied a lot in small areas. Plants had a lot of differences in coverage, especially at a 3 km scale. Soil saltiness didn't vary much, but other factors did. Some areas had more plants and better soil, while others had less. Plants and soil were connected, with more plants where the soil was better. Different types of plants depended on different soil factors. The differences in plants and soil show how the ecosystem works in this area.
