【摘要】：宁夏地处我国大西北高原东部,其耕地资源在国家粮食保障和区内粮食安全、经济社会发展中具有重要地位,为西北干旱区的农业大区。为了促进宁夏耕地可持续利用,提高耕地的粮食和农产品生产能力,在宁夏耕地资源利用现状实地考察基础上,采用1991-2013年《宁夏农业统计年鉴》和宁夏历年国民经济和社会发展统计公报非农用地清查资料及第二次土壤普查资料,分析影响宁夏耕地高效利用的主要障碍因素和生产性问题-耕地面积减少、质量下降、干旱缺水、土壤盐渍化、水土流失、荒漠化、农业经营租放等,总结宁夏高效利用耕地,确保耕地资源数量基本稳定,质量逐步提高的经验,提出了优化土地利用结构和农业生产布局,节水保水高效用水、提高耕地综合生产能力等高效利用耕地的途径。可为宁夏高效利用耕地,确保粮食与农产品安全和农业综合发展提供科学决策依据,并为国内同类地区高效利用耕地提供参考。
[Abstract]:Ningxia is located in the eastern part of the Greater Northwest Plateau of China. Its cultivated land resources play an important role in the national food security, regional food security and economic and social development. Ningxia is an agricultural region in the arid region of northwest China, in order to promote the sustainable utilization of cultivated land in Ningxia. To improve the grain and agricultural production capacity of cultivated land, and on the basis of on-the-spot inspection of the present situation of utilization of cultivated land resources in Ningxia, Using the Ningxia Agricultural Statistics Yearbook 1991-2013, the non-agricultural land inventory data and the data of the second soil census of Ningxia National Economic and Social Development Statistics Bulletin of the past years, This paper analyzes the main obstacles and productive problems affecting the efficient utilization of cultivated land in Ningxia, such as the decrease of cultivated land area, the decline of quality, drought and water shortage, soil salinization, soil erosion, desertification, agricultural management, leasing and so on, and summarizes the efficient utilization of cultivated land in Ningxia. In order to ensure that the quantity of cultivated land resources is basically stable and the quality of cultivated land resources is gradually improved, it is proposed to optimize the structure of land use and the layout of agricultural production, and to save water, conserve water and use water efficiently. Improving the comprehensive productive capacity of cultivated land and other ways of utilizing cultivated land efficiently can provide scientific decision-making basis for ensuring the safety of grain and agricultural products and the comprehensive development of agriculture in Ningxia, and provide reference for the efficient utilization of cultivated land in the same areas in China.
