摘要

引进景观生态学的空间结构分析思路，水土流失空间结构的4个主要元素是斑块、廊带、基面和边缘带。根据黄河河源区地质调查所获实际资料和遥感影象信息，从3个不同的等级层次对河源水土流失的空间结构特征进行了研究。河源区水土流失受自然因素和人类不合理开发利用因素联合控制，但后者的作用更为重要，而且导致了河源新的危害性更大的水土流失类型。河源的水土保持措施是增强全民生态意识，制止短期经济行为。具体途径是（1）保护草场；（2）实施植被、栅栏护岸工程；（3）沙金矿开采后的植被恢复。

Abstract

The thought of spatial structure in landscape ecology is introduced. The patch

cor-ridor

matrix

edge are the main elements according to remote sensing information and material from regional geological mapping in headstream region， and based on the spatial structure features of soil erosion on three scales. Mechanism of soil erosion is put a bridle on spontaneous factor and action of humanity. Measures of soil and water conservation are to enhance consciousness of ecotope and restrain from short-term action paying attention to economy. The specific methods is safekeeping rangeland

safekeeping riverside using plant cover and stockade

resuming plant cover postmining goldmine.
