基于粮食安全的山东省水土资源可持续利用研究

The Study on the Sustainable Use of Land-water Resources in Shandong Province Based on Food Security

分析了20世纪90年代以来山东省粮食安全状况,在综合比较山东省粮食总产量与粮食单产变化情况的基础上,认为山东省粮食生产总体来说比较稳定;通过比较山东省粮食人均占有量及粮食单产在全国所占比重,说明了山东省人均粮食占有量和粮食单产均高于全国平均水平。在此基础上,解析了水土资源状况与粮食安全的关系,总结出山东省水资源匮乏,农业用水紧张,水质污染较严重;耕地面积大且整体质量较好的特点。同时也分析了水土资源在空间上的配合状况,以及水土流失状况。提出了基于粮食安全的山东省水土资源可持续利用发展建议,强调要加强农业基础设施建设,实施多水源联合调度;加强耕地资源监管,综合开发耕地后备资源;加强水土资源污染治理与重点区域水土流失防治。

After the analysis of food security of Shandong Province since 1990s,based on the change of grain output and grain per unit yield,it was considered that food production of Shandong Province was generally stable;through comparing the proportion of per capita possession of grains and grain per unit yield of Shandong Province in the whole country,it revealed that they were higher than the national average level.On this basis,the relationship between land-water resources and food security had been analyzed,and it summarized that Shandong water resources were insufficient,agricultural water was not enough and water had been seriously polluted;and that the cultivated area was large and the overall quality was high.Meanwhile,it had analyzed the spatial pattern of land-water resources and the loss of water and soil.Finally,suggestions for the sustainable use of land-water resources in Shandong Province based on food security had been proposed.It should enhance the construction of basic agricultural facilities and implement united dispatching of multiple water resources;strengthen the supervision of cultivated land resources and comprehensively develop reserve resources of cultivated lands;and intensify the treatment of land-water resources and prevention of the loss of water and soil at key areas.
