盐碱地的生态修复研究

随着人口不断增长和社会经济的发展，耕地面积逐步减少，土地质量也在降低，世界范围内土地盐碱化问题越来越严重。为了科学、合理地治理盐碱地，应当以系统论的观点，从盐渍土资源、植物资源、水资源等诸方面综合考虑，把盐碱地作为一种可利用的资源，根据生态恢复学原理，对盐碱地进行生态修复，统筹开发利用与水土保持、经济效益与景观效果之间的关系，努力拓展盐碱地开发利用新途径，积极推进盐碱地资源的生态利用与产业化开发。

Discussion on Ecological Rehabilitation of Salt-affected Soils

At present, world population is growing, while arable land area is decreasing. Saline land area has reached 954 million hm² in the earth. Thus soil salinazation becomes one of the serious environmental issues with population growth and socioeconomic development. To cope with the situation amelioration and utilization of salt-affected soil is vital and significant. In order to deal with the problem, the way of ecological rehabilitation such as farming measures and biological measures to reclaim and exploit saline soils is feasible and available in view of salt-affected soils as one of the natural resources based on the principle of rehabilitation ecology. During the process, it is crucial to handle well the relations among land exploitation and soil conservation, economic benefits and landscape values.
