长江口采砂方案评价指标体系初探——以东风西沙水库工程采砂方案为例

Preliminary research on evaluation index system of sand mining scheme of Yangtze River estuary

近年来,为改善投资环境,长江口沿江两岸堤内外吹填造地对河道砂石的需求量逐渐增大。大规模无序、盲目的采砂活动已引起局部河势的不利变化,危及长江口防洪及通航安全。为规范长江口采砂行为,维护长江河口的健康,迫切需要建立一套科学的评价指标体系,为评价采砂活动提供方法。结合近年来编制采砂可行性论证报告的实际工作经验,对长江口采砂方案评价指标体系进行了初步探索,提出了评价指标的评价方法与评价标准,供业内同行及采砂管理部门参考。

In recent years, in order to improve the investment environment, the demand of sand mining in river channel for land reclamation along the Yangtze River increases gradually. Large - scale, disorderly and blind sand mining has caused local unfavorable changes of the river regime and threatens the flood and navigation safety of the Yangtze River estuary. In order to regulate the sand mining behavior in the Yangtze River estuary and maintain the estuary healthy, a scientific evaluation index system is set up to provide an evaluation method for sand mining. In the combination of practical experience of preparing feasibility report on sand mining in recent years, the evaluation index system on sand mining in the Yangtze River estuary is studied preliminarily, and the evaluation method and standard of evaluation indexes are put forward for reference.
