摘要
川西北地区沙化土地的急剧扩张已成为国内外关注的重大环境问题,该区域沙化治理存在植物材料单一的问题。本文从成活率、生长情况以及光合特性几个方面分析了4个桑树种在川西北高寒沙区的适应情况,结果表明4个桑树种基本能适应川西北高寒区的立地条件。
Land desertification in northwestern Sichuan has become a major environmental issue,which is concerned all over the world. The monotony of plant species in preventing land desertification has become a crucial restriction to desertification control in northwestern Sichuan. In this paper, analysis is made of the survival ratio, growth condition and photosynthesis of 4 mulberry species. The results have shown that the 4 mulberry species can essentially adapt to the environment in northwestern Sichuan.
