兰州干旱半干旱地区植被恢复模式与应用

干旱半干旱地区植被的恢复是我国生态环境建设中最突出的难点问题之一.在总结多年实践经验和研究成果的基础上,针对兰州地区的立地条件提出干旱半干旱地区植被恢复的基本模式:以当地天然生长且能自我繁殖的植物为种源,在人工正向干预的基础上,引导并培育其繁衍和生长,逐步达到恢复植被的目的.人工干预的模式主要有:封育、植物混交配置、破土导入、破土引导、破土保护等.同时以典型的红砂Reaumuria soongorica群落为主研究了培育和更新技术.

Pattern and application of vegetation restoration in arid andsemi-arid region of Lanzhou, China

The problem of vegetation restoration in arid and semi-arid area is one of the critical issue of ecological environment construction in China. In this paper, the basic pattern of vegetation restoration in arid and semi-arid region of Lanzhou was proposed. Some plant species which are native growing and self-producing were regarded as target plants for further reproduction. Some methodologies, such as fencing, mixing planting, resowing seeds, inducing seed germination and collecting seeds by breaking ground were used for vegetation restoration in typical Reaumuria soongorica community in north Lanzhou of China.
