Abstract
The northwest of China is a vast area with abundant resources and significant potential for develop- ment. However, the ecological system is extremely vulnerable to damage and must be managed carefully. Thus, the Chinese government is strengthening research on improvement and reconstruction of the ecological system and landscape in northwest of China while moving forward with large-scale development in west China. The dis- advantages and vulnerabilities in the northwest area in China are presented. It is suggested that the reconstruction of landscape should be conducted by step by step regionalization across the various ecological systems in the 3.04 million km 2 northwest area of China.

It is based on ecological principles, involving sustainable socioeconomic
