Other Abstract

In view of the development of agricultural industry-resource system in Loess Hilly region,we established
a coupling process model of agricultural industry-resource system following the agricultural ecologicaleconomic
coupling process model,and we analyzed the coupling situation of system.We focused on the
ecological and economic significance of model parameters(k1,k2,k3,k4)and conducted an empirical study
on the Xiannangou watershed.The results show that different parameter combination forms the different
agricultural industry-resource system interactive relationship.After returning farmlands to the natural lands,
the space of resources that relied on environmental systems has reached the limit now,and the development
of industry is not based on the rational and efficient use of resources in Xiannangou watershed.The development
trend of resource system is negatively related to the evolution speed of the resource system and the
industrial system.The development trend of industry system is positively related to the evolution speed of
the resource system and the industrial system.The account in of carbon sink can make the optimized system
evolution speed increase by 2.56times.On the basis of that,the agricultural system can be promoted by
4.66times through rotational grazing and house feeding mode,which makes the resources be rationally and
efficiently used and accelerates the optimization and upgrade of industrial structure.
