摘要: 运用模糊数学方法,以植物生长状况及固沙效果、土壤机械组成和土壤含水量3类指标对高台沙区现存的、定植20 a后的7种防风固沙林配置类型综合评判后,认为花棒+柠条锦鸡儿+梭梭(6 m×3 m)的隔带混交类型、梭梭+花棒(4.5 m×3 m)的隔带混交类型及柠条锦鸡儿(6 m×5 m)为生态健康,综合效益好,可以在高台沙区推广应用。

Abstract: This paper, applying the method of fuzzy mathematics, comprehensively assessed the existed 7 types of windbreaks that have been established for 20 years at Gaotai desert area in the Heihe river basin through analyzing the 3 indexes: growth situation of plants and sand-fixation effect, mechanical components of soils, Soil moisture content. The result reveals that the following 3 windbreak patterns are the optimum: the mixture belt of Headysarum scoparium, Caragana korshinskii, Haloxylon ammondendron (6 m×3 m), the mixture belt of Haloxylon ammondendron, Headysarum scoparium(4.5 m×3 m) and the belt of Caragana korshinskii (6 m×5 m), they are ecologically healthy and economically valuable, and can be applied and extended in Gaotai desert area.

Key words: desert oasis, wind-breaking and sand-fixing system, multilevel fuzzy compositive evaluation
