为了对江苏省沿海地区大量土地进行整治,针对沿海地区盐碱土改良增产效果进行量化以获取整治效果.以江苏省沿海地区的4个土地整治项目为例,从资金投入、过程管理、工程实施、综合效益4个方面选取了27个评价指标组成效益评价指标体系,用统计类比、专家咨询等方法构建了土地整治综合评估模型,得到综合效益评价值,提出了相应的建议和措施,为沿海地区土地整治成效的定量化评价提供了科学依据.结果表明:该研究区的4个土地整治项目实施的总体成效较为显著,大部分指标达到计划要求,具有显著的经济、社会和生态效益,但是各项目单项指标成效评估差距较大,土地整治项目综合评价还有较大的提升空间.评价结果为沿海地区在土地整治实践中有针对性地改进提供了依据和借鉴.

针对沿海新垦区盐土盐份高、土壤结构差、有机质含量少等特点,对沿海新围垦区沟渠边坡高含盐土壤侵蚀开展试验分析,研究土壤侵蚀变化规律,利用实测数据验证模型,分析WEPP模型适用性。通过野外径流小区试验分析及模拟结果说明在自然降雨条件下,沿海新垦区径流小区盐碱土侵蚀主要影响因素是雨量、降雨强度,且均为正相关显著关系。WEPP模型模拟出侵蚀量的模型有效性系数平均为0.543,计算结果表明WEPP能较好模拟沿海新垦区沟渠边坡侵蚀情况,在特殊的自然条件下尚需修正。
