废弃砖瓦窑厂土地复垦及其生态学原理

废弃砖瓦窑厂土地复垦技术包括工程复垦和生物复垦,在具体实施复垦方案时,要遵循生态学原理。工程复垦阶段,除了使被破坏土地恢复到可供利用的物理状态,还要考虑改善生态环境和生物多样性;生物复垦阶段,要按照生物与环境协同进化原理、生态结构稳定性与功能协调性等原理,采用施肥法、绿肥法、微生物法、管理法恢复土壤肥力与生物生产能力。淮安市淮安区范集镇大花村在废弃砖瓦窑厂土地复垦项目中,依据生态学理论,因地制宜,采取适宜的方案进行土地复垦,实现了生态环境的良性循环及土地资源的可持续利用。

The Land Reclamation and Ecological Principle for an Abandoned Brick Factory

The land reclamation technology for an abandoned brick factory comprises engineering reclamation and ecological reclamation, and the ecological principle must be followed in the specific implementation of a reclamation project. At the stage of engineering reclamation, in addition to the restoration of the destroyed land to an available physical state, the improvement of the ecological environment and biodiversity should be considered; at the stage of biological reclamation, in accordance with the principles of the collaborative evolution of biology and environment, the ecological structure stability and function coordination, the fertilization, greenmanure, microorganism and management should he applied to restore soil fertility and biological production capacity. In the land reclamation project for the abandoned brick factory of Dahua Village, Fanji Town, Huaian District, Huaian City, based on the ecological theories, adjusting measures to local conditions, taking the appropriate schemes for land reclamation, a virtuous circle of ecological environment and a sustainable use of land resources have been achieved.
