玛纳斯河流域次生盐渍化弃耕地全面生态重建的新理念

土壤次生盐渍化是限制玛纳斯河流域绿洲农区农业可持续发展的重要因素,经过几十年与盐渍化的斗争,逐步总结出依靠现代科学技术及经济实力,倡导"以人为本"的新理念,贯彻以井灌井排为核心,结合机挖排渠、渠系防渗、膜下滴灌,刮除弃耕地表积盐以及以生物适应环境的新思维等全面生态重建的内部水土开发体系,辅以适宜盐渍化地的耕作、栽培措施,已经使土壤盐渍化得到有效控制,弃耕地已大量收复.对玛纳斯河流域次生盐渍化弃耕地的收复(生态重建)进行相关探讨,以期为干旱区内陆河流域绿洲农区防治土壤次生盐渍化提供模式.

New Conception on the Overall Ecosystem Reconstruction of Secondary Salinization Wasteland in Manas River Valley

Soil secondary salinization is an important restrictive factor which affect the agricultural sustainable development in the agricultural district in the oases of Manas river valley. After the struggle against the salinization for several decades, modern science and economic power were applied progressively, meanwhile the new conception of humanism was advocated. The systemic inner water and soil exploiting of the overall ecosystem reconstruction also should be put into practice. It suggested that to adopt system of technique of irrigation and drainage with well,anti-leaking,trickle irrigation below the plastic membrane, surface salt removing , biological measure and combining suitable measures for salinization cultivation. It improves soil salinization and recovers wasteland effectively. This paper takes the Manas River Valley as an example, the recover of soil salinization wasteland was analyzed in it, so as to provide a model for preventing soil secondary salinization in the oases agricultural district of inland rivers basin in arid region.
