盐碱地农业可持续利用及其评价

改良治理盐碱地、促进盐碱地农业高效利用是保障粮食安全、促进农业可持续发展的重要途径之一。盐碱地农业可持续利用是基于生态适宜性与人类经济社会活动目标,通过农业科学技术进步与发展,获取盐碱地农业生产力的持续维持与提高。通过回顾盐碱地农业利用的研究进展发现,尽管相关技术模式取得了较大进步,但系统的盐碱地资源调查监测缺乏、基础理论研究薄弱、管理体制不完善等问题仍然存在。在对盐碱地农业可持续利用评价内涵进行探讨的基础上,构建了基于技术可持续性、改良模式可持续性以及管理决策可持续性分别评价的技术体系与思路。开展科学的盐碱地农业可持续利用评价,构建盐碱地农业可持续利用的技术与管理支撑体系对促进盐碱地农业可持续利用具有重要意义。

Agricultural sustainable utilization and evaluation of saline-alkali land

It is one of the important ways for cnsuring food security and promoting sustainable development of agriculture to enhance the agricultural efficient use of saline-alkali land.Based on the ecological suitability and social-economic activity goals,the agricultural sustainable utilization of saline-alkali land is through the progress and development of agricultural science and technology to obtain the maintenance and improvement of saline-alkali land agricultural productivity.Through the review of the research progresses on saline-alkali land’s agricultural use,it was found that relevant technical model had been experienced a great progress but survey and monitoring system of saline-alkali land resources was lacked,basic theory was insufficient and management system was imperfect.The paper inquired into the evaluation connotation of saline-alkali land agricultural sustainable use and established the respective evaluation technical system and thoughts in view of technology sustainability,improvement model sustainability and management decision-making sustainability.It is of significant for promoting saline-alkali land agricultural sustainable use to carry out scientific assessment of saline- alkali land agricultural sustainable use,establish technology and management support system of saline-alkali land agricultural sustainable use.
