西北干旱区脆弱景观的生态整治对策

The northwest arid area is specially related to fragile landscape in China. In this paper, the causes of the landscape fragility were mainly studied, namely, natural background and social background, and some suitable measures for landscape rehabilitation of the area were identified. Results indicate that irrational human activities are the main factors affecting the landscape stability of the arid area. These factors include the inadequate recognition of regularity of landscape of this region by humans, unreasonable exploitation activities of oasis, lack of regional coordination in land use patterns, and the series of destruction of desert landscape. Based on the study results, the following measures should be used for landscape rehabilitation of the northwest arid area; 1) setting up macrosystematic, comprehensive, stable, and ecological protection tactics; 2) choosing new agricultural production methods; 3) promoting coordinated development and economy; 4) formulating frugal strategies for water resource exploitation; 5) controlling the size and raising the quality of human population; 6) saving the dangerous landscape types.
