| 摘 要： | 针对我国部分地区固沙成林出现早衰甚至枯死问题,本文对沙地典型固沙植物抗旱性特征、固沙林地水分平衡特征和基于水分平衡的沙地合理造林密度研究进行了论述,明确了沙地植被恢复中,应根据植物的抗旱性特征,对水分循环规律进行量化研究,并参照其地带性植被的特征和立地条件的空间异质性,进行植物种类和密度的规划确定,以期为建立稳定的人工固沙植被提供依据。

| Abstract: | Aiming to solve the problems of presenility and decay of the sand-fixation forests in some sandy areas in China, related factors were discussed in details, such as drought resistance of plants, water balance of sand-fixation forests and optimum afforestation density based on water balance. It was concluded that during vegetation restoration in sandy areas, quantization analysis of water balance should be carried out based on the characteristics of drought resistance of the plants. Distribution patterns of zonal vegetation and spatial heterogeneity of site conditions should also be considered in development of artificial vegetation. |
