摘要
半干旱退化山区干旱与水土流失并存,降雨量时空分配不均,且水热不同步(在春夏,植物常因缺水而枯死),致使生态环境建设中恢复植被的难度大。为此,采用工程整地措施与灌草立体配置模式,发展集流灌草植被。集蓄土壤水分,随着时间的延续土壤水分可不断得到补充和调节,促进灌草植被的快速恢复,实现林业经济的可持续发展。
Drought and soil erosion are coexist in half arid degenerated mountainous area. Where rainfall assignment is uneven in space and time, water and heat are not synchronization （in the Spring and Summer, plants are frequently die for lack of the water）. So that it is difficult to restore the vegetation in ecological environment construction. Therefore, The project adopted the shrub - grass patterns to development vegetation for collection of water. Along with the time the soil moisture could obtain supplement and adjustment, vegetation world be restorated fastly.
