中文摘要:通过参考国内研究的相关文献,运用比较分析方法,从岩溶石漠化概念的内涵、分布格局和量化分级、成因分析和演化过程、综合治理和效益评价等基本问题回顾了我国南方岩溶山区石漠化研究进展:岩溶石漠化的概念和成因已取得了较为一致的认识;石漠化等级评价指标相差甚远,需要建立统一调查研究方法、分级标准和评价指标体系;已探索出了一些较好的治理模式和方法,但治理建设仍然存在很大困难;目前没有成熟的石漠化治理效益评价体系和方法,严重影响了石漠化治理措施的修订和完善。指出了我国岩溶石漠化问题研究应从如下几方面加强:不断创新岩溶石漠化的研究方法;把握岩溶石漠化与人类活动相互作用关系;深入开展岩溶石漠化过程模拟与调控研究;推广和完善岩溶石漠化综合治理技术和模式;重视地球系统科学在岩溶石漠化研究中的运用。在岩溶石漠化与人类活动相互作用关系方面,特别要注意加强石漠化地区土地的生产力和人口承载力的定量研究;实施岩溶山区人类经济活动影响预报和经济社会后果预报,建立岩溶山区生态安全监控预警系统;加强不同时空尺度下岩溶石漠化人文驱动机制研究;确定自然因素和人文作用对石漠化过程的正负面影响和各自的贡献率,建立相应的概念模型和数学模型等。

Progress of research on rocky desertification in South China Karst Mountain
Abstract:Based on the research on rocky desertification of the previous scholars, the actual state of research on rock desertification in South China Karst Mountain is reviewed in this paper from the concept connotation of rocky desertification, distribution pattern and quality grading, cause analysis and forming process, integrated control and effectiveness evaluation and so on. Consensus for the concept and formation cause of rocky desertification have already been reached, but the classification evaluation grade index of rocky desertification are different with each other, so general investigation method, unite classification index and appraise index system should be build. Although a few fairly good comprehensive models and methods have already been proposed, there is still no mature methods and effects evaluation system for desertification controlling, which affects the revision and improvement for governing measures of rocky desertification seriously. So, it is proposed that the researching works should be enhanced in the following respects: innovating the research methods, keeping the interaction of rocky desertification and human impacts in hand, enhancing the study on the process simulation and control measures of karst rocky desertification, popularizing and improving comprehensive treatment technique of karst rocky desertification, and paying special attention to use the geosystem science in karst rocky desertification. Furthermore, in the field of the interaction between rocky desertification and human impacts, it is particularly necessary to stress the quantify research for land productivity and bearing capability, to forecast the effects of human economic activity and economy society consequence to establish ecological security monitor and pre-warning information system in karst mountain, to enhance the study on artificial drive mechanism of differential space-time dimension in the future, to distinguish the effects and contribution rates to rock desertification process between natural and human factors respectively, and to build corresponding concept model and mathematic model.
