【摘要】：通過農業(yè)節(jié)水分區(qū)促進區(qū)域水資源高效利用,緩解農業(yè)用水短缺,為中原經濟區(qū)農業(yè)可持續(xù)發(fā)展提供科學決策依據。針對中原經濟區(qū)水資源短缺、農業(yè)用水量大的現狀,選取地形地貌、氣候特征、水資源利用狀況以及農業(yè)結構4個一級指標18個二級指標,建立農業(yè)節(jié)水分區(qū)評價指標體系。運用主成分分析法對農業(yè)節(jié)水分區(qū)指標進行篩選,再采用系統(tǒng)聚類法對中原經濟區(qū)進行農業(yè)節(jié)水分區(qū)。結合聚類結果和中原經濟區(qū)43個市(縣)的實際情況,將中原經濟區(qū)劃分為4個農業(yè)節(jié)水類型區(qū),并結合GIS技術對其進行空間分析。各個農業(yè)節(jié)水分區(qū)與其地理位置所決定的氣候特征和農業(yè)結構分布有著很好的一致性,應用該指標體系與方法獲得較為合理的農業(yè)節(jié)水分區(qū)。
[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.
