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20a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(6m×3m)的隔带混交类型、梭梭+花棒(4.5m×3m)的隔带混交类型及柠条锦鸡儿(6m×5m)为生态健康,综合效益好,可以在高台沙区推广应用。
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.
