摘要
2003年黄河流域耕地面积占全国的12.4%,粮食总产占全国的7.7%,棉花总产占全国的3.4%,苹果总产占全国的40.6%。尽管粮棉产量占全国的比重不大,然而,黄河流域的农业仍是我国重要的生态屏障,是国家生态安全和区域食品安全的保证。本流域农业生产中存在的问题主要为生产水平低、农业结构单一、社会需求与资源环境之间的矛盾突出等。根据农业生产的现状与存在问题、结构调整的原则和比较优势分析,该流域农业结构调整的关键是强化特色农业的发展,即大力发展特色种植业、草食畜牧业、优质果业和特色生物医药产业。据预测,由于特色农业的发展,2000～2020年本流域农林牧渔业总产值年增长率将为3.9%,农业产值所占比重将下降11.0个百分点,牧业产值所占比重将上升12.1个百分点。
The ratio of the item between the Huanghe River Basin and the country was 12.4% for cultivated area, 7.7% for grain yield, 3.4% for cotton yield, and 40.6% for apple yield in 2003. Though the ratios of the output of grain or cotton between the area and the country were not big, an important ecological protective screen is provided by the basin for the country both national ecological safety and regional food safety. There were some problems in agricultural production of the area, which included the lower productive level, single agricultural structure and the striking contradiction between social needs and the condition of resources and environment. According to the present situation of agricultural production and the comparative advantage analysis, the key of agricultural structure adjustment of the area is developing vigorously characteristic agriculture, which should be the characteristic plant industry, the herbivorous animal husbandry, the fruit industry for good quality and the characteristic biomedical industry. The annual increasing rate of the gross output value of agriculture will be 3.9%, and the ratios between the item and gross output value of agriculture will be decreased by 11.0% for agriculture value, and increased by 12.1% for animal husbandry value in 2000-2020 because of the development of characteristic agriculture.
