我国西南喀斯特地区石漠化问题严重,虽然通过石漠化治理措施遏制了整体扩张趋势,但是治理形势并不乐观,生态环境质量有待进一步改善。针对中国西南石漠化治理存在的治理成果难以有效维持、无法彻底消除人地矛盾、治理难度不断提高等问题,在系统梳理西南喀斯特地区的特殊性、石漠化成因、西南喀斯特地区石漠化综合治理模式的基础上,从重视区域整体治理与系统修复、探索喀斯特生态产品价值实现机制与途径、加强喀斯特地区生态补偿、探索喀斯特地区社会-生态系统的协同机制四方面,提出了面向区域整体治理与绿色发展的对策建议,为我国西南地区生态环境和社会经济协同高质量发展提供科学参考。
Abstract
Despite that the expansion of severe rocky desertification in the karst areas of southwest China has been initially curbed, the situation allows no optimism and the eco-environment needs to be further improved. Effective efforts are required to maintain the achievements of desertification control; the contradiction between human and land cannot be eradicated; and the difficulty of controlling desertification has been escalating. In view of this, we summarized the specific characteristics of the karst areas in southwest China, the causes of rocky desertification, as well as the comprehensive management mode. On this basis, we put forward suggestions on comprehensive regional control and green development in four aspects: highlighting holistic management and systematic restoration, exploring pathways of value realization of eco-products, strengthening eco-compensation, and seeking a coordinated social and ecological system. The suggestions are expected to provide scientific reference for the coordinated high-quality development of eco-environment and social economy in southwest China.
