中文摘要对乌兰布和荒漠沙地生态经济型防护林体系的生态、经济、社会效益评价结果表明:1)在封沙育草灌木固沙林生产系统中,宽带模式的植物盖度比窄带模式提高17~33%;风蚀量比窄带减少约50%;花棒、杨柴、沙拐枣林带的全N含量分别比裸沙地提高75.35、66.20、6.34%;全P含量分别提高128.18、140.33、37.02%;全K含量分别提高0.35、0.76、0.10%;有机质含量分别提高149.05、175.65、76.5%。宽式林带的经济效益为窄式林带的2.01倍。2)在防风阻沙林生产系统中,防风阻沙带防护范围内,风蚀量比荒漠区降低91.3~97.5%。小美旱杨与花棒和新疆杨与沙棘乔灌结合混交林的投入产出比分别是1:8.44、1:18.0。3)在农田防护林生产系统中,林农结构生产系统经济效益是农田生产系统的1.99倍;林果结构生产系统经济效益比用材林增加44.8%;林牧结构人工草场比天然草场经济效益提高4倍左右,即年盈利额平均为4617.84元/hm~2。林药结构生产系统模式,年盈利额平均高达19086.36元/hm~2。林农、林果、用材林等各生产系统的年盈利额分别为2289.30、1327.50、916.80元/hm~2。4)1982~1994年,护渠林较无护渠林保护的干渠减少清淤投资14.6188万元。5)在乌兰布和沙区建立区域性高效大农业开发区是切实可行的。按目前(1993年)老少边穷地区发展经济优惠贷款利率6.48%和物价上涨指数121.7%(上年=100)计算,以贷款方式开发干旱荒漠区的农林牧业,9年后即可收回投资。按12%和16%的年利率计算,投资回收期分别为12年和13年。
英文摘要The evaluation on the ecological economic effects of the patterns of shelterbelt systems in Uanbuhe desert were taken. The results showed that: (1) In the production system of grasses、shrubs and trees shelter belt, The vegetative coverage of broad forest belt was raised by 17-33% comparing with that of narrow; The wind erosion amount decreased by 50%; The total nitrogen amount in the land of Hedysarum scoparium, Hedysarum mongolicum, and Calligonum mongolicum forest belt was raised by 75.35, 66.20, and 6.34% respectively compared with uncovered sands; The total phosphorus amount was raised by 128.20, 140.33, and 37.02% respectively; The total potassium amount was raised by 0.35, 0.76, and 0.10% respectively; The organic matter amount was raised by 149.05, 175.65, and 76.5%; the economic effects of the broad forest belt was raised by 2.01times compared with the narrow one. (2) In the production system of Forest shelter belt, the wind erosion amount reduced by 91.3~97.5% compared with the desert. The input-output ratio of the mixed forest of populus * Xiaozhuanica CV. ’Popularis’ with Hedysarum scoparium and Populus bolleana lauche with Hippophae rhamnoides was by 1:8.44, 1:18.0 respectively. (3) In the production system of farmland shelterforest, The economic benefits of forestryfruit tree was increased by 44.8% compared with the timberforest; The economic benefits of the forestrystock structure of artificial grassland were 5 times of the natural grassland, The profit was 4617.84(RMB)/hm~2 per year. The profit of forestrymedicinal plantation pattern was as high as 19086.36(RMB)/hm~2 per year. The production types of the forestryagriculture and the forestryfruit tree and the timberforest was by 15.62, 85.50, 61.12(RMB)/mu per year respectively. (4) The investment for elimination silt decreased by 146188(RMB) from 1982-1994 due to the benifit of sheltered irrigation. (5) Establishment of agriculture industry in wulanbuhe sandy land is feasible. Based on the loan interest rate 6.485 and the prices rise index 121.7 in 1993, if agriculture、forestry and stockraisng were established on the interest pattern, the investment would be taken back nine years later, and would be back 12 or 13 years later if loan interest was 12% or 16%.
