Plant Drought Resistance and Afforestation Density Based on Water Balance in Sandy Land, China: A Review
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.
