摘要: 讨论了意大利东北部喀斯特环境的变化过程。该区经历了严重环境退化到逐步恢复的过程。造成喀斯特环境退化的因素很多,但主要是过度放牧和开垦,以及樵采和伐木所导致的森林大面积消失,战争也严重地破坏了环境。虽然该区的植树造林工作在12世纪就已开始,但喀斯特环境的成功恢复是在二次世界大战结束以后。环境恢复和治理是一个综合过程,涉及到喀斯特多重价值协调利用,区域社会经济发展与实现城镇化,居民人口素质提高与就业等。

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.
