文摘内容 With world population growth arable land area is decreasing. Saline soil is an important natural resource. However it has not been well reclaimed owing to adverse conditions. Forestation is one way of salty soil utilization; on the other hand, it can improve soil quality as well. The mechanism of salinity tolerance is the basis for tree species selection when planting in salt affected soil. Different plants have various way of salinity tolerance, some are salt-exclusion, e.g. Elaeagnus angustifolia; some are salt-secretion, e.g. Tamarix spp.; some are salt-dilution, e.g. Hordeum vulgare; some are salt-avoidance, e.g. Rhizophora apiculata. Trees are favorable, which are salt tolerant and drought or waterlogging tolerant, as well as grow fast. After tree species have been decided, site preparation including change or exchange of soil is necessary. Meanwhile suitable density of trees and planting time must be carefully considered in terms of soil conditions and climatic characteristics. Now a large scale of forests has been established in salt-affected soil in China by the means discussed in the paper, and protect forest system along coast plays important roles in socio-economic sustainable development and improvement of eco-environment。
