- Abstract:
- In order to reveal the plant population characteristics, population niche status and utilization of limited resources in different soil types of typical grasslands, the plant communities under 12 soil types in the Xilin River Basin were studied, and the TWINSPAN community classification method was used to study the classification of vegetation communities, and the classical niche theory was used to explore the quantitative characteristics of its community composition and the niche characteristics of the main populations in each community(established species + dominant species in each community). The grasslands in the study area are mainly divided into five community types. The average height of the community in the gleyic phaiozems was the highest, the average density of the community in the calcareous chernozem is the highest, the aboveground biomass is the highest in the calcareous phaiozems, and the underground biomass is the highest in the leaching chestnut calcareous soil. There are fewer common species of species composition among common chestnut soils, and the proportion of individual is larger. There are fewer common species of species composition among common chestnut soils, and the proportion of individual is larger. From the perspective of the study area as a whole, Leymus chinensis has an absolute advantage. From the perspective of 12 soil types, Salsola collina is the dominant species. The total niche of Stipa grandis is the largest, and it most widely distributes in the study area, and its niche overlap index with other species in different soil types is also higher. In summary, soil type is an important factor leading to different community compositions and niches.
