摘要
本文分析了江苏新围垦滩涂区灌排工程建设面临的问题,认为淡水资源相对不足,上游来水和当地径流含盐量高、地势低洼以及沟渠易坍塌等是影响水土资源利用的主要限制因素。在此基础上,提出了灌排分开、分区排水、低洼区匡圩以及深斗沟+浅农沟和浅沟+暗管田间排水模式的建议。成果对江苏省新垦滩涂盐碱地脱盐改良,促进水土资源利用具有一定指导意义。
The problems associated with the planning and layout of irrigation and drainage system in reclaimed coastal area of Jiangsu Province are analyzed in this paper. The shortage of fresh water, high salinity of water resources in local area and from upper reaches, low-lying of reclaimed coastal area as well as the prone to collapse of irrigation and drainage ditches were considered as the key limit factors for utilization of soil and land resources in the reclaimed area. Based on the analysis mentioned above, suggestions such as separated arrangement of irrigation and drainage system, division drainage, polder construction in low-lying region, combination of deep sub-feeder ditch with shallow farm ditch and shallow ridges combined with subsurface drain pipe system were proposed. The suggestions might benefit the exploitation of coastal soil and water resources in coastal area of Jiangsu Province.
