石羊河流域干旱荒漠区退化林分修复技术研究

Study on Restoration Technology of Degraded Stand in Arid Desert Area of Shiyang River Basin

石羊河流域干旱荒漠区林分退化较为严重,退化林地存在重新沙漠化的可能,治理难度增加,对民勤绿洲的生存与发展产生了很大的影响。造成干旱荒漠区林分退化的因素有很多,而最为显著的是人为因素和自然因素。通过观测退化林分不同地类利用不同修复方式的修复成效,探索出适合石羊河流域干旱荒漠地区完整高效的退化林分修复方式,为后期的进一步研究奠定基础。

The forest degradation in the arid desert area of Shiyang River Basin is more serious. The degraded forest land may be re desertification, which makes it more difficult to control, and has a great impact on the survival and development of Minqin oasis.The analysis shows that there are many factors leading to stand degradation in arid desert area, and the most significant are human factors and natural factors. By observing the restoration effects of different restoration methods of degraded forests in different land types, a complete and efficient restoration method of degraded forests suitable for arid and desert areas in Shiyang River Basin is explored, so as to lay a foundation for further research in the later stage.
