Abstract: After introducing the concepts of ecological industry and ecological agriculture,the paper brings forward 6 ideas for ecological industrial development especially for ecological agricultural development in Shaanxi-Gansu-Ningxia contiguous area.Firstly,the natural laws should be followed in collocating the ecological agriculture in accordance with ecological particularity in different topographic places.Secondly,based on the diversities of ecological environments,the paper divides the contiguous area into 4 regions which are the southern arid plateau agriculture and forestry region,the middle loess hill agriculture and animal husbandry region,the northern deserts edge animal husbandry and forestry region,and the northwestern irrigated region along the Yellow River,and proposes the ecological agriculture tactics for each region.Thirdly,the grass industry and animal husbandry should be developed,and the agricultural industrialized management must be adopted.Fourthly,the ecological technology should be applied on maintaining the agriculture's “ecological rationality” and the traditional agricultural advantage should be brought into play to reduce the chemical material use.Fifthly,the areas industrial production should be organized on the basis of the model of regional production complexes and the principle of 3R (Reduce,reuse and recycle)to form the scientific territorial industrial cyclic system and to realize clean production.Finally,the prompting and protecting mechanism for ecological industry development should be established.
