摘　　要：压砂地生产力评价的影响因素较多,此次评价在自然资源条件一定的情况下,以宁夏中部干旱地区为研究区域,研究不同地域社会经济条件差异化条件下的压砂地生产力评价指标体系。压砂地生产力评价的指标主要考虑压砂地年限、水利化水平、化学化水平、农业机械化水平和耕地现有人口承载量5个指标,采用TI指数模型进行压砂地生产力评价,并划分相应的评价等级。通过分析得出,压砂地西瓜的产量Y和评价指数TI之间存在线性相关关系Y=1 261.5TI+566.18,即TI指数模型建立的指标体系可以较好的对压砂地生产力进行评价。Many factors can influence gravel-mulched field productivity evaluation,the evaluation must be in the natural resources conditions,the middle arid zone of Ningxia as the study area,study on gravel-mulched field productivity evaluation index system.Index system considers five indexes of sand carrying capacity,water level years,chemical level,the level of agricultural mechanization and the cultivated land population pressure,with the TI index model for gravel-mulched field productivity evaluation index system about the society-economy conditions,the corresponding evaluation grade division.By the analysis of yield,between Yand evaluation index of TIgravel-mulched field watermelon there is a linear correlation between Y=1 261.5TI＋566.18,the index system model can better evaluate gravel-mulched field productivity of social economic conditions.
