长江流域粮食生产态势与潜力

CHARACTERISTICS OF FOOD PRODUCTION AND ITS POTENTIALITY IN YANGTZE RIVER BASIN

通过大量的资料分析了长江流域在进入９０年代后的粮食生产与消费态势，粮食生产过程中存在的主要问题，及其对粮食生产的影响。资料分析表明，长江流域七省一市的粮食生产表现为，粮食单产略有提高，粮食总产徘徊，粮食消费量与居民的经济收入密切相关。农业发展面临的主要问题是，耕地面积减少，水旱等自然灾害频发，对农业的投资比例下降，农民种田积极性下降等。针对上述问题，提出了实现长江流域农业可持续发展的若干建议，尤其是长江流域的中低产田的改造，是发挥长江流域粮食生产潜力的重要途径。

This paper deals with the characteristics of the food production and consumption, main problems faced to the food production in Yangtze River Basin, especially in recent years. The results of this study show that the yield of main crops is increasing to a small extent, the total amount of food production manifests no obvious increase, the expense on food by people is closely related to the income of people. The main problems for the development of the agriculture in Yangtze River Basin are that the cultivated land decreases yearly, the flood and drought disaster occurred often, the investment allocated to agricultural development decreased compared to that for industry and other fields, and the farmers are not so enthusiastic about cultivating the land because of the low economic benefit of the farming activities. Based on above analysis, the authors proposed several countermeasures in order to increase the food productivity and promote the development of sustainable agriculture in Yangtze River Basin.
