摘要
1978～ 1999年 ,广西耕地总量相对稳定 ,但人均耕地面积下降趋势明显 ,人地矛盾突出。耕地利用程度、集约经营程度和利用效益偏低 ,粮食安全形势严峻。预测 2 0 10年耕地总面积可保有 2 5 8 2 3× 10 4hm2 ,仅可满足耕地总需求量的下限要求。采取保护耕地、促进耕地可持续利用和加大对耕地的投入等有效措施 ,是提高粮食单产水平和粮食产量 ,实现粮食安全保障的关键。
During the period of 1978-1999, the gross area of cropland in Guangxi is relatively stable, but the contradiction between human and land is very outstanding. Per capita cultivated land trends on an evident declining;use degree of cultivated land, its intensive management degree and use benefit are on the low side,and food security is on a grim situation. It is forecasted that the gross area of cultivated land in 2010 may retain 2 5 823×10 6 hm 2, which just meets the lower limit of overall cultivated land requirement. For the sake of sound food security, the following available approaches should be adopted: 1) erecting the consciousness of cropland protection, strictly administering the system of basic farmland protection, implementing gross homeostasis of cropland resources; 2) carrying out the protective and inspirit policy of foodstuff yield, safeguarding economic benefit of grain planting peasants; 3) completely improving low yielding lowland, increasing multiple crop index, raising food yielding in unit area, and stabilizing foodstuff planting area; 4)increasing investment to cropland, doing with farmland basic construction, and ameliorating producing conditions; 5)invigorating agriculture by applying scientific and technological advance, and promoting sustainable development of foodstuff production; 6) increasing the power in foodstuff base building, leading farming production to achieve 'two essential transformation', i e., change from planning type into market type, from extensive type into intensive type.
