Spatial Variation of Ecological Countermeasures of Woody Plants in the Yellow River Plain of Western Shandong
Studying the ecological strategies of plants can understand their resource utilization in the environment,and providea theoretical basis for ecological protection and forest management.Taking forest woody plants in three different areas of Liaocheng City as the research object,the leaf area,fresh leaf weight and dry leaf weight of woody plants were determined.C-S-R ternary map was constructed with StrateFy,a tool of C-S-R ratio,to determine the physical and chemical properties of combined soil factors in the sample plot.To explore the relationship between CSR ecological strategies of forest woody plants and environmental factors in the yellow plain of west Shandong Province.The results show that(1)Among the three regions,C(competition type)strategies were mainly adopted in Gaotang area,accounting for 48.1%,and S(stress tolerance type)strategies were mainly adopted in Donga area,accounting for 58.4%.(2)The influence factor with the largest difference among the three regions was leaf total nitrogen content..(3)The selection of different ecological strategies by vegetation is mainly related to soil nitrogen and leaf total nitrogen content.The forest vegetation in different regions of the Yellow River Plain in western Shandong has various ecological strategies,and the limiting factor of different countermeasures is mainly the relationship between soil nitrogen and leaf nitrogen.
