摘要
介绍"十三五"国家重点研发计划项目"西南高山亚高山退化森林生态系统恢复重建技术研究"的主要研究内容、技术路线和取得的进展,展望西南高山亚高山退化森林生态系统恢复未来的研究重点.该项目针对西南高山亚高山退化森林迹地恢复困难、次生灌丛演替缓慢、低效林结构不合理以及生态功能低下等主要问题,从森林恢复演替不同阶段的角度,研发了森林采伐和火烧迹地恢复、次生灌丛生态系统恢复、低效次生林功能提升等关键恢复技术,以及特色资源培育与开发技术,为长江上游生态屏障建设提供了科技支撑.
We introduce the main research contents,technical approaches,and progress of the National Key R&D Program of China,"Research on Restoration and Reconstruction Technology of Degraded Forest Ecosystems in Alpine and Subalpine Regions of Southwestern China,"in the 13 th Five-Year Plan,and we recommend future research focus in the field.To overcome major problems such as difficulty in the restoration of degraded forests in alpine and subalpine regions,slow secondary shrub succession,unreasonable structure of low-efficiency forest,and low ecological services in Southwest China,key restoration technologies such as forest cutting and burning restoration,secondary shrub ecosystem restoration,improvement of low-efficiency secondary forest functions from the perspective of different succession stages of forest restoration,and cultivation and utilization of forest resources were developed in the program.The results obtained provided scientific and technological supports for the construction of an ecological barrier in the upper reaches of the Yangtze River.
