Based on plenty of relevant researches about agricultural development , the dissertation puts forward the agricultural structure adjustment and development strategy of the hhh plain which has great significance both of theory and practice to solve agricultural water resource shortage , to utilize the land resource high - efficiently , to develop sustainable agriculture , to take part in the world farm products market which under wto frame and to increase peasants “ income 系統考查了國內外農業發展及相關研究的基礎上，認為研究黃淮海平原農業結構調整及其發展戰略，對解決黃淮海平原農業水資源短缺，土地資源高效利用，農業可持續發展，并參與wto框架下的世界農產品市場，提高農民收入，具有理論的和現實的重大戰略意義。
At the same time , there are many disadvantage factors , such as the scarceness of natural resources , the deteriorism of the ecological environment , the competition with the international market , etc . the huang - huai - hai plain ( hhh plain ) is the largest plain in china , which is becoming the important agricultural product base of “ the south food supplies transport to the north “ 我國農業發展已經進入了一個新階段，農產品生產能力已經得到提升，但面臨著自然資源、生態環境及加入wto后的國內外市場的多重約束。黃淮海平原是我國最大的平原，已成為“北糧南調”的重要農產品基地，其面臨著全國農業發展相同的境遇，但又有著本區域農業發展特有的挑戰。
The product quality faces up to enormous domestic and international markets challenge and the peasants face up to the slow increasing of their incomes . the shortage of water resource is more serious for the planted system , climatic change and low utilization ratio . cultivated land resource is reducing rapidly for nature factors and urbanization process , etc . the analysis results indicate the resour ces utilization mode in the hhh plain is still high investment , high - energy consumption , and grievous pollution 農產品生產在我國占有絕對優勢，但其受結構調整的影響也發生了波動性變化，其產品質量面臨著國內外市場巨大的挑戰，農民收入也面臨著增長緩慢的挑戰；水資源受種植制度、氣候變化及利用率低等多種因素的脅迫作用，嚴重短缺；耕地資源近年來大量減少，受自然及城市化進程等因素的影響，稀缺程度加大。
The dissertation reviews the agriculture production history , analyzes the status quo , the change of river system , soil evolvement and the forming course of economic position , and discusses the precondition of the agricultural development of the hhh plain . the agricultural system database of the hhh plain is set up by using mapgis software 總體上考察了黃淮海平原農業生產歷史、現狀形勢；淺析了黃淮海平原的水系變遷，土壤演變過程及其經濟區位條件的形成，初步探討了該平原農業發展的先決條件。
The structure adjustment should follow many principles such as the basic theory of regional agriculture development and food safety principia , etc . reviewing from whole industrial structure , the primary industry is decreasing obviously ; the secondary industry shows fluctuant trend ; and the tertiary industry is increasing wholly . the emphases of agricultural structural adjustment of the hhh plain is on the planting adjustment and the planting combining with the animal husbandry 結構調整應遵循區域農業發展的基本理論及糧食安全等多條原則；從整體產業結構來論，第一產業有明顯下降趨勢，第二產業表現為波動變化，第三產業整體上升；該平原農業結構調整的重點是種植業內部的調整、種植業與畜牧業結合。
On the basis of analysis and prediction , this dissertation discusses agricultural development overall regional strategy of the hhh plain and the key lies in support of the technology system and increasing farm capital input 在系統分析與預測的基礎上，探討了該平原農業發展的總體區域戰略，關鍵在于技術體系的支撐及增加農業資本投入。
