【摘要】：通过农业节水分区促进区域水资源高效利用,缓解农业用水短缺,为中原经济区农业可持续发展提供科学决策依据。针对中原经济区水资源短缺、农业用水量大的现状,选取地形地貌、气候特征、水资源利用状况以及农业结构4个一级指标18个二级指标,建立农业节水分区评价指标体系。运用主成分分析法对农业节水分区指标进行筛选,再采用系统聚类法对中原经济区进行农业节水分区。结合聚类结果和中原经济区43个市(县)的实际情况,将中原经济区划分为4个农业节水类型区,并结合GIS技术对其进行空间分析。各个农业节水分区与其地理位置所决定的气候特征和农业结构分布有着很好的一致性,应用该指标体系与方法获得较为合理的农业节水分区。
[Abstract]:Through agricultural water-saving zoning to promote the efficient utilization of regional water resources, to alleviate the shortage of agricultural water, and to provide scientific decision-making basis for the sustainable development of agriculture in the Central Plains Economic Zone. In view of the current situation of water resources shortage and large agricultural water consumption in Central Plains Economic Zone, the evaluation index system of agricultural water-saving zoning was established by selecting four first-class indexes, 18 second-order indexes, including landform, climate characteristics, water resources utilization and agricultural structure. The index of agricultural water-saving zoning was screened by principal component analysis, and then the agricultural water-saving zoning of Central Plains Economic Zone was carried out by systematic cluster method. Combined with the clustering results and the actual situation of 43 cities (counties) in the Central Plains Economic Zone, the Central Plains Economic Zone was divided into 4 agricultural water-saving areas, and the spatial analysis was carried out with GIS technology. Each agricultural water-saving zone is in good agreement with the climatic characteristics and agricultural structure distribution determined by its geographical location. The index system and method are applied to obtain a more reasonable agricultural water-saving zone.
