This project studied the landscape changes, especially the quality and the quantity of the forest resources, of Bilahe Forestry Bureau of Daxingan Mountain in recent decade, assessed three critical forest hydrography functions (eg., interception of canopy, interception of litter layer and accumulation of soil) and their changes, explicitly expressed the spacious relationship of the forest hydrography function with GIS, established the security resistance face model of forest hydrography function, supplied a foundation for the ecological security assessment in this region.

将大兴安岭林区嫩江流域景观变化与流域生态安全、景观生态建设相结合，进行跨尺度景观动态与过程关联研究，以嫩江流域水文变化为重点，结合当地特有景观和生态系统的变化，揭示森林景观动态和人类活动对流域生态环境的影响机制，探索景观格局与过程及其调控问题，提出流域生态风险评价指标体系、森林资源可持续经营优化模式和流域生态建设措施。.
