摘　　要：文章对茫崖地区紫花苜蓿人工草地建植进行了分析研究,力求安全稳妥推进人工草地建设。用土地适宜性评价方法对紫花苜蓿生产性能进行了评价,结果表明,能够完成1茬生产。在此基础上用数学模型单因素平均气温估算其生产潜力,得:低、中、高三种投入模式下青干草产量分别为6300、4650、2250kg/hm^2;以同等质量青干草购入价3.5元/kg计算产值,成本毛利分析法核算收益,纯利润依次为+6855、+6804、+1263元/hm^2;生产成本依次为:2.41,2.04,2.94元/kg;投资效益依次为:45.11%,78.84%,19.1%。生态社会效益显著,综合评价认为,该地区建设紫花苜蓿草地可行,但在建设中应强化生产基础,适度生产规模。the establishment of artificial grassland of alfalfa in Mangya area was studied systematically,and the construction of grassland was promoted safely and safely.The production performance of alfalfa was evaluated by land suitability evaluation method,and the results showed that it could complete one stubble of production,on the basis of which the production potential was estimated by single factor average temperature of mathematical model,and the results showed that the yield of green hay was 6300,4650 and 2250 kg / hm2,respectively, under the three input modes of low,medium and high,and the yield of green hay was 6300,4650 and 2250 kg / hm^2,respectively.When the output value of the same quality green hay purchase price is 3.5 yuan / kg,the net profit is 6855,6804,1263 yuan / hm^2;production cost is 2.41,2.04,2.94 yuan / kg;investment benefit is 45.11%,78.84%,19.1% respectively.The ecological and social benefits are remarkable,and the comprehensive evaluation shows that it is feasible to construct alfalfa grassland in this area.However,in the construction, we should strengthen the production foundation and moderate production scale.
