该研究是用营林综合治理模式在绿州外围风沙危害的咽喉地带,通过设置封滩育林育草带,形成保护绿洲农田的第一道防护屏障、营造防风阻沙固沙林带形成第二道绿色防线、营造绿州外围基干林带形成第三道绿色防线,三者相结合的“三位一体”风沙综合治理营林技术防治风沙危害。经对比,这一综合营林模式是防治风沙危害的最有效途径。该项技术弥补了传统模式治理风沙危害治标不治本的单一性,其关键技术在于将传统的封滩育林育草、防风阻沙固沙林带、基干林带营造的相关技术措施通过合理配置,按照生态系统的功能有机结合起来。
The research is to establish the first protective barrier to protect the farmland of oasis by setting the closed beach for raising forest and grass with the comprehensive forest management model in the throat area harbored by wind and sand in the periphery of Green State, Defense line, creating a green belt around the Green Belt of Green State to form the third green line of defense, and combining the three with “Trinity” to comprehensively manage silvicultural forest technology to prevent and control wind and sand damage. By contrast, this integrated forest management model is the most effective way to prevent and control wind and sand damage. The technology makes up for the unity of the traditional model of sandstorm damage management, and its key technology lies in that the traditional technical measures of seafloor breeding, windbreak sand and sand belt, and basic forest belt can be rationally allocated, in accordance with the ecosystem The function of organic combination.
