中文摘要:
      高标准农田建设是提高农作物单产、改善农用地质量、提高农业生产力十分必要的工作。河北省黄骅市地势平坦,耕地广布,土地利用潜力巨大,是高标准农田建设的重点地区,也是严重的缺水区。开展基于高标准农田建设的水资源供需分析和评价,探索新的土地整理技术措施,可以科学合理利用水资源,提高农用地利用效率。运用基于水文响应单元的水资源模型方法对研究区水资源供需量进行计算,通过ARCGIS软件平台进行空间分析,最终形成基于高标准农田建设的水资源供需分析评价。结果显示,距离海岸较近的黄骅市东部水土资源属于极度充沛区和充沛区,处于黄骅市南部以及西北部部分地区为平衡区,而处于西部和中部的部分地区为缺水区和极度缺水区。
英文摘要:
      The construction of the high standard farmland is very necessary to improve farmland quality, increase crop yields and raise agricultural productivity. Huanghua City of Hebei Province situated in Heilonggang River basin is seriously short of water, but it is flat and the farmland is widely distributed. The potential of land utilization is great so that it is a key area for the construction of high standard farmland. To carry out the analysis and assessment of high standard farmland construction based water resources supply and demand as well as the probe of the new land consolidation techniques and measures can make the water resources used rationally and land utilization efficiency improved remarkably. In this paper, the water resources supply and demand volume was calculated with hydrological response unit based water resources model method and the spatial analysis was made with the MAPGIS, then the analysis and assessment results were obtained high standard farmland construction based water resources supply and demand. The results showed that water and land resources are extremely abundant in the eastern part of the city near the coast, are balanced in southern and northwestern parts of city and are short or extremely short in the western and central parts of the city.
