| 摘 要： | 目的]对江苏沿海农田改造的生态影响进行评价。方法]以射阳沿海农田改造为例,通过资料收集、实地调查与监测、专家咨询、文献研究等方法,构建了沿海农田改造的生态影响评价指标体系,包含生物资源、土壤、植被、水环境4个子系统,共12个指标。结果]江苏沿海农田改造对土壤、生物资源、植被、水环境都有一定的影响,准则层土壤、生物资源、植被、水环境指标的权重分别为0.614、0.219、0.118、0.049,土壤指标所占权重最大,说明农田改造对土壤环境影响较大。12个指标中,核心的指标依次为土地垦殖率(权重0.389)、种群密度(权重0.164)和土壤有机质含量(权重0.088)。因此,在以后此类工程的环境影响评价中,应突出上述主要特征因子的识别与评价、监测等内容。结论]该研究为江苏沿海资源的可持续利用和环境管理决策的制定提供了科学依据。

| Abstract: | Objective] The study aims to assess the impact of farmland improvement on ecological environment along coastal areas of Jiangsu Province.Method] Taking the coastal farmland improvement of Sheyang County,Jiangsu Province as an example,an indicator system of environmental impact assessment(EIA) for coastal farmland improvement was established based on data collection,field survey and monitoring results,expert consultation,literature study and other methods,including four subsystems(biological resource,soil,vegetation and water environment) and 12 indicators.Result] The weights of soil,biological resource,vegetation and water environment were 0.614,0.219,0.118 and 0.049,and the top weight of soil shows that farmland improvement had a great influence on soil.Among the 12 indicators,the most important indicators with higher weights were reclamation rate of the land(weight 0.389),population density(weight 0.164) and the content of soil organic matter(weight 0.088).Therefore,in EIA of such kind of projects in the future,we should give prominence to the identification,evaluation and monitoring of the main characteristic factor above.Conclusion] The research could provide scientific references for the sustainable utilization of resources and establishment of environmental management policies along costal areas of Jiangsu Province. |
