中文摘要	干旱对豫北园林景观的土壤肥力影响较大,研究干旱对豫北园林景观绿色植被的生态结构损毁情况,对于生态保护和抗旱救灾意义重大。本文以豫北地区干旱园林景观为例,提出干旱对园林景观绿色植被生态结构损毁分形的研究方法。干旱条件下通过设计豫北园林景观土壤结构分形模型和绿色植被的分形结构模型,研究不同干旱损毁程度下,相关绿色植被土壤中的水稳性团聚体,得到土壤干旱与绿色植被生态结构分形维数之间的关系。研究结果表明:水稳性团聚体含量与豫北地区绿色植被生态结构损毁程度的关系为正相关,土壤团聚体的分形维数变化,导致绿色植被下土壤物理性质发生变化。
英文摘要	Drought has a great influence on the soil fertility of garden landscape in northern Henan Province. It is of great significance to study the damage of drought to the ecological structure of green vegetation of garden landscape in northern Henan Province for ecological protection and drought resistance and disaster relief. Taking the arid garden landscape in the north of Henan Province as an example,this paper puts forward the fractal research method of the ecological structure damage of the green vegetation caused by drought in the garden landscape. Under drought condition,the fractal model of landscape soil structure and the fractal structure model of green vegetation in northern Henan Province were designed to study the water stable aggregates in related green vegetation soils under different drought damage degrees,and the relationship between soil drought and fractal dimension of ecological structure of green vegetation was obtained. The results show that: the relationship between the content of water-stable agglomerate and the damage degree of green vegetation ecological structure in northern Henan is positive correlation.
