中文摘要	黑河中游是我国西北干旱区重要的粮食基地,研究其农业结构变化及其驱动因素对农户种植决策及推动当地农业发展具有一定参考意义。论文以位于黑河中游地区的张掖市为例,基于统计年鉴和农户问卷调查数据,从地块尺度分析了研究区20012014年期间农业结构变化,并在定性分析的基础上,从地块与农户两个层面,运用二元Logistic模型及投入-产出法定量分析农业结构变化驱动因素。结果表明:1)研究区作物种植类型趋于多样化。2001年,研究区主要种植作物为小麦、玉米、大麦及小麦和玉米套作,其种植地块数占所调查总地块数的81%,2014年种植作物种类增多,且蔬菜、马铃薯、油菜等经济作物种植数量较2001年有所上升。2)由种植小麦为主(占总地块数的31%)转变为种植制种玉米为主(占总地块数的38.7%);套作转单作。2001年,共有58个套作种植地块,占调查总地块数的22%,其中小麦和玉米套作最多,有47个地块;而在2014年,作物套作地块数锐减为2个,小麦和玉米套作全部转换为其他单作,其中51%转为制种玉米;水稻种植消失,主要转为普通玉米。3)地块层面上,种植地区的海拔、灌溉定额、河源来水量对农业结构变化影响非常显著(显著水平达到1%),地下水对农业结构变化影响较为显著(显著水平达到5%)。4)农户层面上,农户作为理性经济人,收益是影响其种植行为的最关键因素,其次是政策因素(在5%的水平上显著),务农劳动力与劳均耕地面积也有一定的驱动作用。
英文摘要	Since the middle reaches of the Heihe River is an important grain base in the arid area of Northwest China, studying the agricultural structure change and its driving factors in this area has certain reference significance for farmersdecision- making on planting and promoting the development of local agriculture. However, there are few studies on the change of agricultural structure and its driving factors at the plot scale. Based on the statistical yearbook and the survey on farmers, this paper analyzes the changes of agricultural structure in the study area during 2001- 2014. The paper analyzes quantitatively the driving factors of agricultural structure change by using binary Logistic model and input- output method at two levels, household level and plot level. The results showed that: 1) The crop types in the study area tend to diversify. In 2001, the main planting crops in the study area were wheat, maize, barley and wheat- corn relay intercropping, whose number of plots accounted for 81% of the total number of plots. In 2014, the types of planting crops increased and the number of cash crops (vegetables, potatoes, rape) also increased compared with those in 2001.2) The mainly planting crop in the study area changed from wheat (31% of the total plots) to corn (38.7% of the total plots), and intercropping changed to monoculture. In 2001, there were 58 intercropping plots (accounting for 22% of the total plots), most of which were wheat- corn relay intercropping plots (47 plots). In 2014, there were only two intercropping plots, and wheat- corn relay intercropping plots all converted to monoculture plots, of which 51% plots changed to corn plots. All rice plots turned to maize plots. 3) At the plot level, the elevation of the planting area, the irrigation quota and the water supply from headwaters have significant effects on the change of agricultural structure (significance level is 1%). The impact of groundwater on agricultural structure change is also significant (significance level is 5%). 4) As rational economic men, the most important factor affecting the planting behaviors of farmers is income. Policy factors (at 5% of significance level), agricultural labors and the area of cultivated land per capita also have effects.
