Impact assessment is an important process that helps the policy makers to understand the consequences of possible and actual government interventions. Assessing the impacts and consequences is considered as applicable means for policy makers and planners of projects, since not only it measures and presents the plans’ developments, but also for determining their impacts on the target group. Therefore, the purpose of this paper was to assess the impacts of laser-land-leveling technology in Iran, comparing the impacts among two groups of farmers adopting traditional-leveling and laser-land-leveling projects and identifying factors influencing perception regarding laser-land-leveling technology impacts. The research draws on a mixed-methods approach, which includes two distinct research phases. First, 375 farmers were selected using survey based on stratified random sampling for quantitative part. Twenty-Seven farmers were also interviewed in the qualitative phase. The most important impacts of laser-land leveling were uniform germination of the crop, uniform distribution of water, decrease of soil erosion, increasing positive competition, and increasing net income. In addition, the results revealed that adopters of laser-land leveling expressed more impacts than another group. Attitude towards water and soil resources’ conservation was the most important variable to predict the impacts’ perception among traditional-leveling adopters. It is necessary to officials to increase the information of farmers regarding different consequences of the project and contributing them to make proper decisions for farm management.

技术扩散的影响评估：混合方法分析

影响评估是一个重要的过程，可以帮助决策者了解可能的和实际的政府干预的后果。评估影响和后果被认为是项目的决策者和计划者的适用手段，因为它不仅可以衡量和介绍计划的发展，而且可以确定计划对目标群体的影响。因此，本文的目的是评估激光土地平整技术在伊朗的影响，比较采用传统土地平整和激光土地平整项目的两组农民之间的影响，并确定影响对土地激光感知的因素。平整技术的影响。该研究采用混合方法，其中包括两个不同的研究阶段。第一，采用分层随机抽样调查的方法，对375名农户进行量化。在定性阶段还对27位农民进行了采访。激光土地平整最重要的影响是农作物的均匀发芽，水的均匀分布，土壤侵蚀的减少，积极竞争的增加以及净收入的增加。此外，结果表明，采用激光平地的人所产生的影响要比另一组人大。对水土资源保护的态度是最重要的变量，可用来预测传统级别的采用者对影响的看法。官员们有必要增加农民对项目不同后果的了解，并为农民做出适当的农场管理决策做出贡献。
