Main work
Study on the structural regulation of planted forest ecosystems. For the site conditions in the T'ai-hang Mountains where the soil thickness is less than 15cm, techniques for improving the microhabitat of barren mountainous areas and promoting the construction of vegetation in a quasi-natural artificial manner are proposed. To address the issue of the stability formation mechanism in the current artificial forest system, a dynamic coupling expression model for optimizing the structure and stability of planted Pinus tabuliformis forest was established. Furthermore, an efficient and sustainable structural regulation technology system based on plant competition for water and light resources was proposed for the low efficiency of agroforestry systems in semi-arid mountainous areas.
Biodiversity research in planted Pinus tabuliformis forest. To address the issues of poor continuity of understory vegetation, single forest structure, and low biodiversity in planted P. tabuliformis forest, the high contribution of rare species to the distribution pattern of species richness in P. tabuliformis communities was discovered. This leads to proposals for biodiversity protection and forest management strategies in planted P. tabuliformis forest.
Nutrient cycling in forest ecosystems. In response to the insufficient research on nutrient cycling in the forest ecosystems of southeastern Tibet, studies indicate that fir forests have characteristics of low nutrient cycling and are in a stage of good nutrient accumulation. Additionally, the study reveals that young Chinese juniper artificial forests in the growing season in the rocky mountains of North China are more restricted by nitrogen.
Research on the service functions of forest ecosystems. Currently, there is limited research on the role of suburban forests in regulating the atmospheric environment. Research reveals the spatiotemporal variations of air negative ions and major atmospheric pollutants in Jiulong Mountain and their relationships with various environmental factors. Furthermore, the impact of the litter layer on the physical properties of the soil and its water storage capacity in the thin and infertile soil of the Jiulong Mountain area in Beijing is discussed. Lastly, a balanced factor and yield factor based on the value of ecosystem services are constructed to study the ecological carrying capacity of the ecological conservation and development area.
Research on plant stress resistance. Research on plant stress resistance is conducted from a genetic perspective, elucidating the role of CBF gene family members in resisting low-temperature stress and enhancing plant cold resistance. Additionally, high-quality candidate resistant genes in Populus euphratica are selected, and the synergistic regulation of plant stress resistance by the small molecular heat shock protein Ssu-sHsps with transcription factors and functional genes is revealed.
