对沙棘资源涵养水源、防止水土流失和保护农田等方面的生态效益进行了调查以及价值量化分析，结果表明，沙棘的水保功能与林木生长量呈正相关；生态效益与林地枯枝落叶层厚度正相关；沙棘资源的生态效益是经济效益的2.11倍。
The ecological benefit of seabuckthorn resources in water conservation, soil erosion prevention and farmland protection were investigated and the quantitative analysis was carried out. The results showed that there was a positive correlation between the water conservation function of seabuckthorn and the growth of forest trees. The ecological benefit was positively correlated with the thickness of litter layer Related; Seabuckthorn resources of ecological benefits is 2.11 times the economic benefits.
