摘　　要：根据能值理论计算了山东省黄河流域各地市的产量因子、生态足迹的深度与广度及结构份额,以此来度量和研究黄河流域产粮区自然资本存量和流量及其结构的时空特征。结果表明,绝大部分地区资本存量利用程度越来越大、资本流量越来越小;在资本存量消耗中草地和水域引起的比重高达95.12%;资本流量利用中,耕地所占份额在减小报告期为68.67%;建设用地比重在增加,报告期平均达26.03%,个别地区高达38.47%。近8年个别地区耕地的份额减少了12个百分点、建设用地增加了6个百分点。可见,城市化进程加快导致的建设用地规模的扩张不断地侵占着耕地的份额、侵蚀着区域粮食安全的基础。政府部门应加大对商品粮产区的资本存量尤其是草地和水资源的保护,激励充分开发和合理利用资本流量、调整利用结构,遏制建设用地继续侵占耕地在资本流量中的份额,从土地生产力上实现"占补平衡",激励农业生产大户依靠技术进步提高生物产出水平,保障国家粮食安全。This paper calculates the yield factors, depth and breadth of ecological footprint and structures of the sample areas, based on Energy Theory, in order to measure and research the temporal and spatial characteristics of natural capital stocks and flows as well as the structures of the Yellow River grain-producing areas. The results show that the degree of capital stock utilization in most regions is becoming larger, with increasingly smaller capital flows, and that the proportion of grassland and water areas in the capital stock consumption is up to 95.12%. It has also been found that the share of arable land decreased during the reporting period by 68.67%, and that an increase in the proportion of the construction land on the reporting day averaged 26.03%, in some special areas as high as 38. 47%. In recent eight years the arable land share has decreased by twelve percent with an increase of six percent in terms of the construction land in some special areas. It is obvious that scale expansion of construction land resulting from accelerating urbanization has encroached on the share of arable land and threatened regional food security. Therefore, the government departments should increase the protection of the capital stock, especially grassland and water resources in grain producing areas, encouraging the full development and rational utilization of capital flows, adjusting the structure of utilization, and curbing construction land occupation of cultivated land in the capital flow continues, so as to achieve the ＂balance＂ of land productivity and encourage large groups of agricultural production to improve the level of output by technological progress, ensuring national food security.
