摘　　要：通过对退化生态系统生态恢复与重建问题的探讨,根据生态学原理和可持续发展的基本思路,确定恢复与重建的最终目标是形成生态与经济的和谐统一。结合喀斯特地区特殊的地质背景和土地退化特点及过程分析,认为植被恢复是喀斯特山区生态恢复与重建的根本途径。按照山地生态因子分配规律和基岩裸露程度的差异,分别提出了不同的生物恢复途径和对策。针对山区农村经济、能源和耕地矛盾,配套相应的工程措施,可有效减少或降低人为干扰。恢复对策强调系统性和整体性,生物措施与工程措施互相补充和促进。This article confirmed the target of restoration or reconstruction ecosystems to form the harmonious systems by discussing the problems existing in eco-resumes process of degraded ecosystems. Based on the principle of ecology and ideas of sustainable development, a special geological environment of Karat area and land degradation process were analyzed. It was considered that vegetation restoration was uhimate approach of resumes or reconstruct ecosystems in Karst mountain areas. According to its frangibility and the distributive regularity of Karat environment eco-factors, it was suggested that biologic countermeasures reduce disturbance from human activities. Some engineering measures were offered aiming at the rural area economy, energy sources and cropland.
