中文摘要	在简要介绍辽宁省沙化土地现状及危害基础上,以阜新为例,从农业、水利、畜牧业、林业4个领域系统总结制约沙地植被恢复与建设中存在的诸多问题。同时,为了科学恢复重建沙地植被,提高已退化的生态系统的生产力,优化当地的生态环境,针对近10年来气候变化、人为不合理经济活动造成新沙源等问题,从有效预防、科学恢复、提高建设水平、提升经营水平、加强研究示范5方面提出相应对策:1)有效预防,要转变生产方式,严于执法,积极推进立法和新机制的执行力;2)科学恢复,优先采取恢复天然植被,建设人工植被时提倡适度造林;3)提高建设水平,要努力提高生态建设和生态经济水平,探索生态移民等植被建设的新模式;4)提升经营水平,正确评价现有人工植被,找出科学经营的方法;5)研究示范,研究主要生态修复技术,建立主要植被恢复的软、硬件示范。提出的对策可为有关部门和人员合理恢复、高效建设、科学经营沙区人工与天然植被提供参考。
英文摘要	In this paper the present situation of desertification and its damage in Liaoning Province is briefly introduced.Taking Fuxin as an example,problems restricting sand vegetations restoration and construction were summarized from four aspects: agriculture,water conservancy,livestock industry and forestry.Meanwhile,for scientifically restoring vegetation,improving the degraded productivity of ecosystem,optimizing the local ecological environment,in view of the formation of new sand source due to the climate change and human irrational economic activities in the past decade the author put forward corresponding countermeasures from five aspects: effective prevention,restoring based on scientific method,improving the standard of construction,enhancing the management level,strengthening research and demonstration.1) effective prevention,transforming productive modes,stricting law enforcement,actively promoting legislation and execution of the new system.2) scientific restoration,taking priority to restoration of natural vegetation,promoting appropriate afforestation when planting artificial vegetation.3) increase the level of construction,striving to improve the level of ecological construction and ecological economy,exploring new mode of ecological migration and vegetation construction.4) enhance the management level,correctly evaluating the present artificial vegetation,finding scientific management methods.5) research and demonstration,studying ecological restoration techniques,establishing the key vegetations restoration and demonstrations mode.
