摘 要:宁夏农业生态环境的干旱化趋势,已经成为制约区域农业可持续发展的主要障碍。在干旱灾害环境背景下,基于区域内部环境质量的非均质性,初步提出并构建了宁夏避灾农业经营模式,即引黄灌区高效集约与规模经营的避灾农业亚模式和南部山区高效利用与综合发展的避灾农业亚模式。较以往农业发展模式,避灾农业生态模式更具经济上易于接受,运行上易于操作,收益上高效的特点,特别是对于优化农业投资环境,实现区域可持续发展意义重大。The arid tendency of agricultural eco-environment needs to innovate radically the existing unreasonable models and outdated ideas of agriculture developing in Ningxia Hui Autonomous Region.
