中文摘要：

在粮食供给方面，发展中国家主要从粮食生产、粮食流通、粮食贸易等方面采取相应的促进政策提高粮食的自行生产能力以及调剂余缺的能力。在粮食获取方面，主要通过提高人们的劳动生产率和收入水平来提高其获取粮食能力，并加强安全网的建设应对临时冲击。发展中国家提升粮食供给和获取能力的政策与减贫的政策存在内在的必然联系，缓解和消除贫困是确保发展中国家粮食安全的根本。加强对农业的支持是改善发展中国家粮食安全的最主要途径。

英文摘要：

In terms of food supply, developing countries mainly take the appropriate promotion policies in food production, food distribution and food trade to enhance the ability of food producing and the ability of adjusting surplus and deficiency. In terms of food access, developing countries mainly enhance their ability of food access by improving labor productivity and strengthen the construction of safety net to deal with temporary shocks. The policies to improve the ability of food supply and food access have inherently inevitable contact with poverty reduction policies. Mitigation and eradication of poverty is fundamental to ensure food security in developing countries. Strengthening support for agriculture is the main way to improve food security in developing countries.
