内蒙古河套灌区农业资源承载力提升对策研究

Countermeasures for Improvement of agricultural resource carrying capacity in Hetao Irrigation Area in Inner Mongolia

河套灌区是国家和内蒙古自治区重要的商品粮、油、畜产品生产基地。提高其农业资源可持续利用水平,对保障黄河流域生态安全,提高我国粮食供给安全保障能力具有重要意义。文章运用农业资源承载力综合指数分析法,对河套灌区农业资源承载力进行分析,结果表明:2016年河套灌区土地资源承载力不断提高,其粮食盈余率达到76.74%;水资源承载力较2010年有所下降,且已临近水资源的最大承载力。2010—2016年河套灌区农业资源综合承载力逐渐提升。

Hetao irrigation area is an important production base of commodity grain,edible oil and livestock products in Inner Mongolia.It has great significance for improving the sustainable utilization of agricultural resources in this region,as well as for guaranteeing the ecological security of the Yellow River basin and improving the safety assurance ability of the food supply.In this study,the agricultural resource carrying capacity in Hetao irrigation area was assessed by using the comprehensive index analysis method.The results showed that the carrying capacity of land resources in this region was characterized by a continuously increasing trend,and the grain surplus rate in 2016 reached up to 76.74%.Meanwhile,the carrying capacity of water resources in this region in 2016 was slightly decreased compared with 2010,which was close to the maximum bearing capacity of the water resources.The comprehensive carrying capacity of agricultural resources gradually improved during the period of 2010 to 2016.
