接坝地区沙地植被恢复与重建技术研究

通过对丰宁小坝子沙地不同植被恢复技术的效果分析，提出了冀北接坝地区植被恢复技术。在河道、沟口、滩地采用乔灌草低等植物相结合的复合防风固沙植被恢复技术营建防风固沙林；在裸沙地和流动沙丘通过沟施营养调理剂改良土壤促进的天然植被快速恢复，通过生物网格沙障固沙为植被恢复提供适宜的环境条件。

Studies on the Technology of Restoration and Reconstruction of Vegetation in Sandlot Near Altiplano Bashang

The results of restoration of vegetation in Xiaobazi sandlot were analysed and a series of techniques were concluded.In dried river channel,mouth of channel and beach,wind-breaking and sand-fixing forest should be constructed using the technology of reconstruction of compounding vegetation of trees,shrubs,grasses and lower plants. In sandface and mobile sand dune,in order to accelerate the recovery of vegetation the nutrients should be enriched by application of nutritious regulator,and in order to improve the environmental conditions biological checkboard may be planted along the contour or cutting the wind.
