| 摘 要： | 土地荒漠化是人类所面临的重大环境问题,针对阜新地区的荒漠化土壤,采用分形理论研究了其机械组成的分形特征,从而揭示土地荒漠化的演变规律,同时分形特征也体现了荒漠化的形成机制。研究结果表明,正在发展沙化区的自组织程度要高于相对稳定沙化区,土地荒漠化的演变首先是从沙土的骨架变化开始,而后经过环境、气候和人类活动等的影响向混合复杂型沙土转变。

| Abstract: | Desertification is the most serious environmental problem in the world today. Fractal feature of granularity composition was studied by using the fractal theory in view of desertification soil in Fuxin district, thereby evolution patterns of desertification was promulgated. The result shows that the self - formation degree of the developing desertification areas was higher than the relatively steady desertification areas. Evolution of desertification was beginning at the formation of sandy soil, and then the sandy soil be came complex by the effect of environment, climate and anthropo - activity. |
