英文摘要	The ago-pastoral ecotones in north china are located in the transitional zones between the semi-hu-mid agriculture area and the arid/semiarid pastoral area. The ecotones are the economic links between the agri-culture areas and the pastoral areas in north China, and play a very important ecological role in fixing sand, restoring water, purifying the rivers and control ling soil erosions in the headwaters and upper reaches of the rivers in north China. The ecology, however, has seriously degenerated since recent decades, which includes mainly the frequent occurrence of droughts, serious degeneration of vegetation, serious soil erosion and land de-sertification. In this paper, the current situation and causes of the ecological degeneration in the agro-pastoral e-cotones in north China are analyzed, the five principles are put forward for restoring and regenerating the ecolo-gy, they include the principles of endemic species, diversification and rational distribution of species, dominance of protection and assistance of regeneration, dominance of prevention and combination of prevention and control, and coordination of ecology and economy. Some measures are also put forward for restoring and regenerating the ecology, they include the rational planning, withdrawing from farming to afforesting and grass planting, equal consideration of both ecological effects and economic returns, mutual benefits of the ecological restoration and re-generation and the social and economic development.
