Application of technologies has an important role in agricultural development. Identifying and assessing the impacts of agricultural technologies is necessary. This study aimed at assessing the impacts of laser levelling economically, socially, environmentally, and technically in the viewpoint of the agricultural experts and identifying factors determining their perception of the impacts. The study samples (151 experts) were selected using multi-stage random sampling in Fars Province, Iran. The results revealed that experts considered uniform distribution of water, using conservation tillage, facilitating agricultural activities, decreased water consumption and decrease of water wasting as the most important technical impacts of laser levelling technology. The most environmentally important impacts were the decrease of soil erosion and retention of crop residues. Experts stated the most significant social impacts as improvement in villages living conditions and sense of belonging to rural areas. Besides, an increase of income and reduction of inputs costs were among the economic impacts of laser levelling technology. According to the results, attitude towards water and soil resources conservation and environmental beliefs had the highest direct effect on individual perception toward impacts. Practical recommendations have been presented based on the results of the study.

技术应用在农业发展中具有重要作用。识别和评估农业技术的影响是必要的。本研究旨在从农业专家的角度评估激光整平对经济、社会、环境和技术的影响，并确定决定他们对影响看法的因素。研究样本（151 名专家）是在伊朗法尔斯省使用多阶段随机抽样选择的。结果显示，专家们认为均匀分布的水、使用保护性耕作、促进农业活动、减少用水量和减少水浪费是激光整平技术最重要的技术影响。对环境最重要的影响是减少土壤侵蚀和保留作物残留物。专家表示，最显着的社会影响是改善村庄生活条件和农村归属感。此外，收入的增加和投入成本的降低也是激光整平技术的经济影响之一。结果表明，对水土资源保护的态度和环境信念对个人对影响的看法的直接影响最大。根据研究结果提出了切实可行的建议。收入的增加和投入成本的降低是激光整平技术的经济影响之一。结果表明，对水土资源保护的态度和环境信念对个人对影响的看法的直接影响最大。根据研究结果提出了切实可行的建议。收入的增加和投入成本的降低是激光整平技术的经济影响之一。结果表明，对水土资源保护的态度和环境信念对个人对影响的看法的直接影响最大。根据研究结果提出了切实可行的建议。
