华南西部滨海湿地调查及主要成果

通过遥感、单波束测量、地质取样、海水取样、钻探、地下水采集与监测等多种调查手段及工作方法,首次在我国华南西部开展1∶10万滨海湿地地质调查与生态环境评价工作,对滨海湿地类型及分布、滨海海域地形地貌、沉积物环境质量、海水环境质量、生态地质演化、地下水化学要素进行综合分析与研究。项目系统查明了该区滨海湿地类型、分布、生态环境现状及其主要影响因素,对湿地生态地质环境质量进行了综合评价,构建了华南西部滨海湿地地质调查技术方法体系和生态地质环境综合评价体系,提出了滨海湿地保护和恢复的建议,为后续我国南方滨海湿地调查提供了示范。

Investigation achievements of coastal wetland in western South China

The authors carried out the 1∶100 000 geological survey of coastal wetland and evaluation of ecological environment for the first time in western South China, based on remote sensing, single beam measurement, geological sampling, seawater sampling, drilling, groundwater collection and monitoring. The types and distribution of coastal wetland, topography of coastal waters, sedimentary environmental quality, seawater environmental quality, evolution of ecological geology, and chemical elements of groundwater were comprehensively analyzed and studied. The authors ascertained the types, distribution, ecological environment situation and its main influencing factors of coastal wetland in the study area. The eco-geological environmental quality of the wetland was comprehensively evaluated. The authors built the technical method system of geological survey and the comprehensive evaluation system of eco-geological environment in coastal wetland of South China, and put forward some suggestions for the protection and restoration of coastal wetland. The achievements can provide a demonstration for the follow-up survey of coastal wetland in South China.
