摘　　要：不同空间尺度的地理单元都有成带性的表现。研究沙被生态系统的成带性,对于深化沙被生态系统空间结构规律性的认识及其保护、修复与利用具有重要意义。通过对不同沙被生态系统的实地考察和卫星影像解译发现:沙被生态系统的水平结构存在从其边缘到腹地的带状或近似于带状的规律性分布,我们称为沙被生态系统水平结构的成带性;沙被生态系统成带性主要表现在沙被表面形态的成带性和植被的成带性两个方面;沙被表面形态的成带性是植被成带性形成的基础,同时植被对沙被表面形态和稳定性具有一定的影响。The geographical units of different spatial scales have the performance of zoning.It is of great significance to deepen the understanding of spatial structure regularity,protection,restoration and utilization of sand cover ecosystem to study the zoning of sand cover ecosystem.Through field investigation and satellite image interpretation,it is found that the horizontal structure of the sand bed ecosystem shows a regular distribution of banded or similar to banded from its edge to the hinterland,which is called the zonation of the horizontal structure of the sand bed ecosystem.The zonation of sand cover ecosystem is mainly manifested in the zonation of sand cover surface morphology and the zonation of vegetation.The zonation of sand cover surface morphology is the basis of vegetation zonation,and vegetation has a certain influence on the surface morphology and stability of sand cover.
