干旱气候变化对西南干旱河谷农业的影响及适应性对策研究(英文)

The Impact of Arid Climate Change on Agriculture of Dry Valley in Southwest China and Its Adaptive Countermeasures

在干旱气候变化情境下,西南干旱河谷生态环境的脆弱性和发展滞后,会进一步强化其农业不利的发展环境。为改变干旱河谷农业资源独特但利用粗放的现实,需妥善处理好资源开发与生态环境的关系,明确干旱河谷农业适应干旱气候变化的原则。文章最后提出发展现代草地畜牧业、加强特色农业与农业产业化建设、注重生态农业开发、构建现代农业节水技术推广体系、大力发展服务"三农"的第三产业和因地制宜,进行水利设施基础建设和可再生能源开发的西南干旱河谷农业适应性对策建议。

The eco-environmental vulnerability and underdevelopment of the agriculture in Southwest China would strengthen its disadvantage conditions further on the condition of arid climate change.It is necessary to deal with the relations between resource utilization and eco-environment finely and ascertain the adaptive principles on the dry valley agriculture to the arid climate change in order to change the extensive utilization of the special agricultural resources.The paper gave some adaptive countermeasures that develop modern rangeland husbandry,strengthening the special agriculture and agricultural industrialization,emphasis on the ecological agriculture development,constructing the extension system of water-saving modern agriculture,encouraging the service industry related to ＂agriculture,peasants and the countryside＂,constructing water utilization facilities,and exploiting the renewable energies.
