海涂是一种独特的湿地环境和重要的自然资源,一般由潮上带、潮间带和潮下带构成。辽河口海涂资源丰富,类型多样,开发潜力较大。本文以遥感技术为主要手段,结合典型地段野外工作,采用多时段、多波段TM,MSS假彩色合成卫星像片和黑白卫星像片,依据地物的影像特征进行判读和制图,判读出了辽河口海涂资源的类型、空间格局和土地利用状况,并对海涂的成因、动态变化及分布规律进行了分析。为本区域海涂资源的开发、生态环境的保护、经济的规划和建设,提供了科学依据。
Tidal flat is a unique wetland environment and an important natural resource, usually composed of tidal zone, intertidal zone and tidal zone. Liaohe Estuary rich in resources, diverse types, development potential greater. In this paper, remote sensing technology is the main method, combined with the typical field work, using multi-period, multi-band TM, MSS false color composite satellite photos and black and white satellite images, according to the image features of the interpretation and mapping, The type, spatial pattern and land use status of Tidal Flat are analyzed. The causes, dynamic changes and distribution of Tidal Flat are analyzed. It provides a scientific basis for the development of the Tuhai resources in the region, the protection of the ecological environment and the economic planning and construction.
