基于生态重建的石漠化山区土地整理项目规划

Planning of land consolidation project based on ecological rehabilitation in rock desertification mountainous area

实现石漠化山区土地持续利用最有效的方式即是通过生态重建,而土地整理正是改造土地利用的有效选择,通过把生态恢复措施融入土地整理规划设计中,能有效地实现土地整理和石漠化治理的双重目的。该文通过土地整理项目规划实例,规划方案以生态重建为核心内容,具体分析了不同地表形态与土地平整工程、岩溶环境与农田水利设计、植被恢复与农田林网建设以及生态系统保护与道路建设的规划设计方法;并对项目工程设计结果从农田建设和生态恢复两方面进行了跟踪监测,结果表明,基于生态重建前提下的石漠化山区土地整理项目规划,是改善石漠化山区生态环境和实现土地持续利用的有益探索。

Ecological rehabilitation is an effective way to realize the sustainability of land use in rock desertification mountainous, and land consolidation is an effective choice for improving land use. So, it can create a new route to achieve the goals of land consolidation and control of desertification by means of ecological rehabilitation. Taking a typical land consolidation project as an example, based on ecological rehabilitation, the paper analyzed the characteristics of land consolidation engineering design for rock desertification area, which including land leveling project design in different types of surface configurations, engineering design of farmland water conservancy in karst region, and vegetation restoration for farmland shelterbelt network construction, and road design for protecting ecosystem. Moreover, the paper made tracing monitoring on the ecological restoration and farmland construction effect based on the results of these engineering designs. Results showed that the planning of land consolidation project based on ecological rehabilitation was beneficial for the improvement of ecology and sustainable land use in rock desertification mountainous area.
