According to the agricultural problems in resources, environment, food and grain security, low profitable agriculture and natural disasters in today＇s world now, how to make rational use of resources and ensure the safety of ecological environment have become the key of the sustainable development of agriculture. This paper briefly introduced the research objectives and significance of the northern suburban multifunctional eco agriculture mode, and discussed the environmental pollution, dispersion of agricultural management pattern, in complete demonstration of technology, unreasonable planning, and unclear function of the current northern suburban multifunctional ecological agriculture. The suggestions and ex pectation were put forward about the construction of fruit and vegetable production safety, multifunctional landscape ecological agriculture mode of low carbon and environmental pro tection and high efficiency, and the basic research of the high value eco agriculture of the northern suburban were put forward, which provided scientific bases for the northern subur ban multifunctional eco agriculture constructions, the eco efficient agriculture development and sustainable development of agriculture.
