摘　　要：采用系统研究法对安全建植紫花苜蓿人工草地与可持续利用进行了深入研究。结果表明:该地区土地适宜紫花苜蓿,并能够完成一茬生产。用数学模型单因素平均气温估算其生产潜力,在低、中、高三种投入模式下产值(青干草)分别为11250、23250、11250元/公顷;用成本毛利分析法核算收益,相应分别为+4638、+13779、+16305元/公顷。草地建设对于当地生态环境保护和社会事业发展均具有一定促进作用。综合评价认为:该地区建设紫花苜蓿草地可行。The safety production and sustainable utilization of alfalfa artificial grassland were studied by systematic approach.The results showed that the land was suitable for the construction of alfalfa forage and could complete the crop produced of alfalfa.The single factor average temperature production potential method of forage yield calculation model was used to calculate the output(green hay)of three different input models(low,medium and high)was 11,250 yuan/hm^2,23,250 yuan/hm^2 and 11,250 yuan/hm^2,and the profit is calculated by cost-gross profit analysis method,corresponding to+4638 yuan/hm^2,+13779 yuan/hm^2 and+16305 yuan/hm^2,respectively.Grassland construction plays a certain role in promoting the protection of local ecological environment and the development of social undertakings.The comprehensive evaluation shows that it is feasible to build alfalfa grassland in this area.
