摘要
为探索不同植物群落对土壤结构的改良作用,运用激光粒度分析方法和分形理论,研究了迎河小流域7种植物群落的土壤颗粒组成及粒径分布非均匀特性。结果表明:1)土壤颗粒分形维数和多重分形参数D_0、D_1和D_2与土壤粘粒和粉粒含量显著正相关,与砂粒含量显著负相关,多重分形参数D_1/D_0与粘粒含量显著正相关,与粉粒和砂粒含量相关性不明显。2)不同土地利用类型土壤颗粒分形维数和多重分形参数表现为林地>荒草地/灌木林>旱梯田,其中防护林地(麻栎林和杂木林)表现出更强的结构异质性。结论:森林群落通过增加土壤中粘粒与粉粒细粒物质含量提高土壤分形维数,特别是增加粘粒含量提高土壤质地均匀程度和结构异质性。
For exploring the effects of different plant communities on soil structure,the composition of soil particles and heterogeneity characteristic of soil particle size distribution under seven plant communities of yinghe watershed are studied with laser particle- size analysis method and multi- fractal theory.The results showed that;1) The fractal dimention and multifractal parameters(D_0,D_1 and D_2) are significantly positively correlated with the clay and silt soil particles,negatively correlated with sand soil particles,the multifractal parameter D_1/ D_0 is significantly positively correlated with the clay soil particles,and no correlation with silt and sand soil particles;2) The fractal dimention and multifractal parameters of different land uses are the following order as forest land,wasted land/shrubbery and terraced fields,and protection forests(Quercus acutissima and Populus linn) show stronger structure heterogeneity than others.The conclusion is;the plant communities can increase soil fractal dimension by raising the content of clay and silt soil particles,especially increase the heterogeneity of soil texture and soil structure by raising the content of clay soil particles.
