摘要
岩溶洞隙和孔隙、强降雨、土壤流失、较大坡度的地貌以及人为因素对森林植被的破坏是岩溶石漠化的主要原因。岩溶地区生态环境的脆弱与其恢复的难度决定了岩溶森林保护的重要性。要限制薪材及薪材树种的消耗 ,控制用材消耗 ,以达到保护的效果。以恢复森林植被为主题的岩溶石漠化治理包括半石漠化山地、耕地、工矿地的治理和石漠化土地的治理。
Holes and pore space of limestone, heavy rainfall, soil loss, the topography of slope and the destroy on forests imposed by humankind were the main causes of lithification in karst area. The ecological environments fragility and the difficulty of vegetation recovery of karst area revealed the importance of forest protection. Control of fuel wood and timber consumption was helpful. Lithification control with the theme of recovering forest vegetation was composed of the control of semi lithification mountainous areas, arable land, mine and lithification land.
