毛乌素沙地榆林沙区经济林配置结构研究

Study on the Structure of Economic Forests in Yulin Desertificational Area of Maowusu Sand Regions

在毛乌素沙地榆林沙区的自然条件下，对葡萄、苹果和沙棘等经济林木结构配置、生产性能调查和分析，提出了优化的结构配置模式。结合柠条种子资源和利用价值，建议该沙区建立柠条生产基地及系列产品的开发。

Based on the investigation of current structure and productivity of economic forests of grape (Vins vinifera), apple (Mains pumtila)and seabucrthorn (Mippophac rhamnoides) in the southeast of Maowusu sand regions,the optimized structure models of three forests are provided for the area. According to the resource and potential economic uses of peashrub (Caragana korshinskii), it is suggested that research on the cultivation and development of this species should also be conducted in this area.
