Abstract: An analysis on karst environment change processes in the North-eastern karst areas of Italy was made in the paper. Karst environment there experienced serious environmental degradation and gradual restoration in past years. Karst environmental degradation there was caused by over grazing and over cultivating through cleaning forest as well as firewood and timber industry. The war also contributed to the degradation. Restoration of the degraded environment succeeded since the end of the second World war although works for reforestation began in the 12th century. The successful process of environmental restoration and control in the region was an integral one, which involved multi value exploitation, adjustment of regional social economic structures, realization of urbanization, improvement of populotion quality, and provision of new eaploymert opportunities for the locals. The significance of the experience of karst environment restoration of north-easernt Italy for Chinese karst environment control was also discussed in the paper.
