| Abstract | This study aimed at applying Remote Sensing and Geographical Information System (GIS) as tools for spatial data analysis and field survey methods towards the zoning and management of razor clams (Solen strictus Gould) in the muddy coast between the Mae Klong and Tha Chin rivers, Gulf of Thailand. In Remote Sensing method, Landsat TM images taken in 1993 and 2000 were classified to detect change in land use patterns and emerged area during low tide of the study area. The field survey method was conducted to collect sediment, seawater and biological (razor clam) samples for chemical and physical analysis. Sediment samples were analyzed for sediment texture, organic matter and heavy metal (Cd, Pb and Zn). Seawater samples were taken to determine pH, temperature, salinity, dissolved oxygen and ammonia. For biological samples, the analysis was focus on population density and size of razor clam. The results were analyzed and overlaid using GIS techniques. Spatial information such as administrative boundary, road network, village, infrastructure and emerged areas were acquired from GIS and derived from manual interpretation of remote sensing imagery. Environmental data such as sediment and seawater were used as input sources to create database. The GIS database were overlaid and calculated for suitability class by Linear Combination Model (Razor Clam Model). The razor clam zones were grouped into 3 classes including high suitable, medium suitable and low suitable. The high suitability area of razor clam covered about 5596.33 ha (58.91 %). The medium and low suitability areas covered approximately 2337.72 ha (24.61%) and 1565.47 ha (16.48%), respectively. The final zoning and management were the results from integrating razor clam zoning, expert suggestions and socio-economic data that includes the participation of Tambon Administrative Organization (TAO). |
