喀斯特山区林草间作生态恢复过程中土壤质量演变规律及其评价-----以贵州“晴隆模式”为例

"Qinglong mode" of Guizhou province, which could conserve and water, improve soil environment quality, is a feasible approach for Karst rocky desertification area with social benefits and ecological benefits through silvipastoral system. The studies about soil quality of cultivated soil in domestic has been carried out mainly concentrated in the eastern region. To further understand the national soil quality change, We must be developed the research to the types of soil around nation. "Qinglong Model" provides an excellent case of benign restoration of degraded soil quality in typical Karst area, According to the theory problem about the temporal and spatial difference, change law, influencing factors of soil quality and the demand of regional soil resource management practice, We will development the research work with multi discipline and multi process and joint research to analysis of temporal and spatial characteristics of soil quality in Karst mountain area , reverse evolution process of determining factors, evolution of Karst soil quality and its influence, selection of characterization of Karst environmental changes of soil quality index, revealed Karst mountain forest grass intercropping ecological restoration and evolution of soil quality in the process, to establish the evaluation index system of soil quality, These work will promote the study on soil quality in the Karst soil types of China, perfect the theoretical basis and scientific evaluation method of "Qinglong Mode", improve the ecological recovery efficiency of the mode and improve the regional ecological security.

通过林草间作达到蓄水保土、提高土壤质量的贵州"晴隆模式"是实现喀斯特石漠化治理社会效益与生态效益兼顾的可行途径。然国内已开展的土壤质量的研究主要集中于东部地区的耕地土壤，要进一步深入了解全国土壤的质量变化，就须将研究拓展到各地的土壤类型。"晴隆模式"提供了典型喀斯特地区退化土壤质量良性恢复的绝佳案例，针对该模式生态恢复过程中土壤质量演变的时空差异、演变规律、影响因素、评价体系等理论问题和区域土壤资源管理的实践需求，开展多过程、多学科联合研究，分析喀斯特山区土壤质量正逆向演变过程中的时空特征，确定喀斯特山区土壤质量演变规律及其影响因素，遴选表征喀斯特环境土壤质量演变的指标，揭示喀斯特山区林草间作生态恢复过程中土壤质量演变规律，建立土壤质量评价指标体系，将推动中国土壤质量研究在喀斯特土壤类型的实质性进展，完善"晴隆模式"的理论基础和科学评价方法，提高该模式的生态恢复效益，增强区域生态安全保障。
