中文摘要	【目的】调查分析广西大化县岩溶区生态重建的研究现状,为进一步深入研究大化县岩溶区生态修复与可持续发展提供参考。【方法】利用实地考察、总结以往相关研究和查阅相关文献资料等方法调查广西大化县岩溶区退化生态环境概况及其石漠化成因,分析其生态环境恢复与重建技术研究现状。【结果】大化县的地形地貌以岩溶峰丛洼地、岩溶峰林山地为主;土地资源贫乏,耕地分散,土地生产力低;森林覆盖率低;原本脆弱的生态系统加上剧烈的人为干扰,导致了石漠化。通过封山型、封育型、补播补植型和保留促进型模式进行森林生态系统的构建,提高了森林覆盖率;通过筛选适合大化县石灰岩山区的高产优质经济作物品种及栽培技术,畜牧业成为主要的经济来源,大力发展畜牧业,保护生态环境,促进了生产可持续发展。【建议】开展大化县岩溶区生态环境脆弱性评价研究;开展大化县岩溶区石灰土退化的主要影响因素研究;建立大化县岩溶区生态适应性修复试验示范区。
英文摘要	【Objective】The present study was conducted to investigate and analyse research advances of ecological reconstruction in karst area of Dahua county, Guangxi, in order to provide references for further research on ecological restoration and sustainable development of Dahua county.【Method 】Through on-the-spot investigation, summing up previous related research and reviewing relevant literature, the ecological degradation situation of karst area of Dahua county and its reasons of rocky desertification were investigated to analyse research advances of ecological environment restoration and reconstruction technique in karst area of Dahua county.【Result】The investigated results showed that, the main land-form of Dahua county was dominated by karst peak cluster depression and karst peaks mountain. Dahua county was characterized by poor land resources,dispersive cultivated land,low land productivity and low forest coverage rate. And the rocky desertification of Dahua county were caused by human disturbance to original flimsy ecosystem. Furthermore,the forest ecological system was constructed by means of enclosure breeding,replanting and retaining,so as to improve forest cover rate. Through screening high-yield and fine economic crop varieties suitable for karst region of Dahua county and studying its cultivation techniques, the ecological environment could be protected, in order to promote sustainable development of economy.【Suggestion】The corresponding suggestions were put forward to restore ecosystem and develop ecological economy sustainably of Dahua county, which included studying vulnerability of ecological environment and main influence factors of karst calcareous soil degradation, and establishing demonstration area of ecological adaptability restoration of karst area.
