北京东灵山风景区山顶退化草甸恢复技术研究

针对东灵山风景区的气候环境特征，从时间、恢复地、覆盖物、植物材料等的选择和播种量的确定5个方面对该区植被恢复的关键技术进行了分析，并通过温室模拟实验确定了最适覆盖物和最适播种量，最后建立了山顶退化草甸恢复的小型实验区。实验结果表明：恢复实验区内植被的覆盖度为75％。大黄、灰菜、老鹳草等14种草本植物可以作为示范区内初期植被恢复的主要材料。

Research on Vegetation Restoration Technology to Degradation Meadow at Peak in Scenic Spot of Dongling Mountainous, Beijing

Based on climate environment characters, according to five factors about time, land type, overlay matter, plant material, seed quantity choice, the key technology about vegetation restoration was analyzed, and the most suitable overlay matter and the most suitable seed quantity were confirmed through greenhouse simulation experiment. Finally, small scale experiment zone about degradation meadow restoration in peak was built. The experiment result shows that vegetation coverage is 75 percent, and fourteen herbage plant include Rheumfranzenbachii, Chenopodium album, Geranium eriostemon and so on were regarded primary material of vegetation restoration in demonstration initial stages.
