辽河三角洲海岸带环境地质与调查研究

GEO-ENVIRONMENTAL ISSUES ALONG THE COAST OF LIAOHE RIVER DELTA AND SUGGESTIONS

海岸带处于陆地和海洋的结合部,既是海陆相互作用最为活跃的地带,又是社会经济活动最发达、人类活动对环境影响最严重的地区,同时也是自然生态环境相对脆弱的地区。辽河三角洲地区区位优势独特,土地后备资源丰富,战略地位重要,但存在许多环境地质问题。近期辽河三角洲的调查研究工作始于20世纪60年代,除了个别与矿产开发有关的详细研究,大多研究是小比列尺的区域性的调查工作,同时也缺乏系统、全面、完整的调查资料,难以满足现在社会的发展需要。针对辽河三角洲生态环境保护与沿海经济带开发建设的需求,在全面分析存在的环境地质问题和社会经济需求的基础上,为辽河三角洲海岸带调查任务指出新方向。

As one of the most prosperous economic regions in the world, the coastal zone is characterized by the active interaction of ocean and continent and the strong impact of human activities. The ecological environment of the zone is vulnerable. The Liaohe Delta, being well known for its rich land resources, is important in a strategic point of view. However, there remain many geo-environmental issues to be solved. Geological survey started early in 1860s in the Liaohe Delta. Most of the follow up researches, mainly small scale regional geological surveys were related to mineral resources. It is obviously not sufficient to meet the current social demand. We need more systematic and comprehensive data for environmental studies so as to meet the needs of the society and the public. In order to protect the ecological environment for construction of a prosperous coastal economic zone, we proposed a new round coastal survey orientated to geoenvironment at the Liaohe Delta after analyzing the current environmental issues.
