摘要
岷江上游干湿季节分明,在局地焚风效应的影响下,还出现干旱河谷的隐域性分异现象,农业也呈现立体分布格局。对岷江上游干旱气候变化对农业发展的潜在影响进行了分析,提出以集约农业技术推广建立干旱河谷生态农业区、优化土地利用格局,采用科学整地方式,构建生态农业推广技术保障体系和合理规划居民用地的岷江上游干旱河谷农业适应性对策。
The upper reaches of Minjiang river have distinct wet and dry seasons, under the influence of the foehn wind effect, it also show the features of dry valley and agriculture shown solid distribution patterns. The paper analysed the potential impacts of climate change on agriculture, and also suggested establish eeo agricultural areas through intensiving agricultural extension, optimizing land use patterns, adopting the scientific method, building eco-technology protection system of agricultural extension and rational planning, residents and agricultural adaptation strategies in the dry upper valley of Minjiang river.
