【摘要】：近年来,阿拉善盟腰坝灌区社会经济快速发展,人口和耕地数量逐步增多,农业用水和生活用水需求随之日益提高。由于当地地下水资源缺乏补给且总量较少,导致水资源稀缺程度加剧,加之当地落后的生产生活用水方式和落后的用水意识,更加剧了用水矛盾的产生。腰坝灌区居民的主要谋生方式是售卖农产品,所以农业用水占当地水资源利用的极大比例,如何有效利用提高农业水资源利用效率,改进农业水资源利用方式,节约农业水资源占比,对腰坝灌区未来的可持续发展有着重要作用。本文以阿拉善盟腰坝灌区农业水资源利用的现状、农业水资源利用效率分析、农业水资源利用效率低下的原因以及提出相应的对策作为全文的主线。在农业水资源利用效率分析中,对当地农户年龄、学历、耕作年限、土壤种类、耕作亩数对农业水资源利用效率影响进行了分析,深入地阐述了该地农业水资源利用效率情况。得出当地农业水资源利用的产量效率为1.49,农业水资源利用的产值效率为2.81,并且发现这两个指标呈现出同增同减的趋势。和全国以及邻近省份相比较,腰坝灌区农业水资源利用效率偏低。研究发现农业水资源利用效率影响因素中农户的学历、种子价格和土壤种类与农业水资源利用效率率呈正相关趋势；耕作亩数在60亩以下时,亩数对农业水资源利用效率没有明显影响,但当大于60亩时,农业水资源用利用效率同耕作亩数呈负相关趋势；年龄在31～40岁间,农业水资源利用效率最高,其他年龄段农业水资源利用效率均有所下降；耕作经验与农业水资源利用效率没有明显关系；耕作成本在531～550元/亩时,农业水资源利用效率最高,其他成本区间农业水资源利用效率均有所下降。在分析因素和存在的问题后,从水价、农业节水政策、农业节水技术和农业种植结构调整等几个方面提出了对策,寻求提高水资源利用效率的措施,以更好地促进当地农业的发展。
[Abstract]:In recent years, the rapid development of Alashan Yaoba irrigation area social economy, gradually increasing the number of population and arable land, agricultural water and domestic water demand increased. Due to lack of local groundwater resources supply and the total amount is less, leads to the scarcity of water resources and intensified, when backward and backward mode of production and living water water awareness, more drama water contradictions. The main way of living of residents is the sale of Yaoba irrigation of agricultural products, so the agricultural water accounts for the vast majority of local water resources, how to effectively use to improve the utilization efficiency of agricultural water resources, improve the utilization of agricultural water resources, saving agricultural water resources accounted for, plays an important role in the future of Yaoba irrigation area the sustainable development. This paper takes the Alashan waist status of agricultural water resources utilization dam irrigation area, analysis of agricultural water resource utilization efficiency, effective utilization of agricultural water resources The reasons for the low rate and put forward the corresponding countermeasures as the main line. In the agricultural water use efficiency analysis, the local farmers' age, education, cultivation age, soil type, farming acreage utilization efficiency on agriculture water resources were analyzed, discussed the situation of agricultural water use efficiency and the yield obtained. The efficiency of agricultural water resources utilization of the local 1.49, the output value of agricultural water resource utilization efficiency is 2.81, and found that the two indicators showed a trend to increase with the decrease. And the country and neighboring provinces compared to Yaoba irrigation by water resource efficiency is low. The study found that the factors influencing the efficiency of agricultural water resources in farmers the degree and type of soil seed price and utilization of agricultural water resources efficiency rate was positively related to farming acreage of 60 acres in the trend; when the acreage of agricultural water resource utilization efficiency is not Significantly, but when more than 60 acres, agricultural water resources utilization efficiency with farming acreage was negatively correlated; at the age of 31 to 40 years old, the agricultural water resources use efficiency is the highest, the utilization efficiency of agricultural water resources in other age groups were decreased; and the farming experience of agricultural water resources utilization efficiency has no obvious relation to farming; the cost in 531 ~ 550 yuan / mu, agricultural water use efficiency is the highest, the use efficiency of other cost of agricultural water resources decreased. In the analysis of the factors and problems, from the price of water, water saving agriculture policy, and puts forward some countermeasures in several aspects of agricultural water-saving technology and the adjustment of agricultural planting structure, to improve the efficiency water resources utilization measures, to better promote the development of local agriculture.
