西部农业水资源的创新管理与永续利用

Innovation Management of West Agricultural Water Resources and Sustainable Development

当前中国西部农业面临的水问题发生了重大变化,一是从农业防洪、灌溉等传统问题发展成为水资源、水环境、水生态、水灾害四大问题并存的多重危机;二是各类问题的规模从局部或部分河段扩展为流域性、区域性的影响。对西部农业水的治理应遵循循环再生原则、协调共生原则和持续自生原则:调整农业结构,增强水资源的再生功能;合理开发利用水资源,增强共生功能;加强生态环境保护与管理,提高水资源自我调节功能,实现持续自生。

Currently, great changes take place in west China agricultural water resources, from traditional flood control and irrigation to such four issues as water resources, water environment, water ecology and water disaster, and from regional partial river segment to drainage basin and regional issue. The management of west agricultural water should follow the principle of circulation regeneration, coordinative symbiosis and sustainable self-generation. Agricultural structure should be regulated to increase regeneration function of water resources. Water resources should be rationally developed and utilized to increase symbiosis function. Protection and management of ecological environment should be enhanced to raise self-regulation function of water resources to realize self-generation of water resources.
