柴达木盆地荒漠化地区节水体系的研究

柴达木盆地的生态环境恶化问题已十分突出,防治荒漠化,恢复植被的生态环境建设工作已显得十分重要.本区的限制因素是"水".因此通过几种灌溉方式的试验研究提出柴达木盆地荒漠化地区灌溉模式:①退化农田、草地进行植被恢复宜采用畦灌 绞盘式喷灌的灌溉模式;②行道树、防风固沙林、农田防护林的灌溉采用畦灌 滴灌或直接采用滴灌的灌溉模式;③行道树、防风固沙林、农田防护林的灌溉采用渗灌的灌溉模式.

Discussion on Water-saving System for Desert Zone of Chaidamu Basin

The problem of ecological environment deterioration has been very serious.So the ecological environment construction of desert controlling and vegetation recovery is important.Water is the key limitation factor in this area.Several irrigation modes for desert zone of Chaidamu Basin are put forward through experimental research in this paper.It is proposed that the mode with border irrigation and winch sprinkler irrigation is suitable for the vegetation recovery of degenerated farmland and grassland,the mode with border irrigation and drip irrigation or only drip irrigation is suitable for the irrigation of roadside tree,windbreak and sand-fixation forest and shelter-belt for farmland,the mode with infiltrating irrigation is suitable for the irrigation of roadside tree,windbreak and sand-fixation forest and shelter-belt for farmland.
