Abstract:
Bangkok; the hub of business, commerce and service has the impact from economic growth. This phenomenon impacts on the Bangkok urbanization. Work places and residences are increasing to serve the roles of Bangkok whereas the agricultural areas are gradually diminishing. Due to the lacks of efficient land use plan and measuring controls, The causes of decreasing of the agricultural area come from unfruitful agriculture and land speculation of investors. Besides, some areas face the problems of coastal erosion and water quality caused by the expansion of industries. The waste water problem effects to the aquatic farm. The study covers the characteristic of geographic, economy, social aspect and human settlement and then analyze the impacts including the tendency of land utilization so as to find out the land use potential. The research is aiming to formulate the suitable land use plan in relation to the natural structure, potential and basic need of local residents in the southern part of Bang Khun Thian district for sustainable development. The result of this study can be summarized as follows. The topography in this area is a flood plain and has tidal waves twice a day. The area covers with canal network. The land use is mostly agriculture and aquatic farm in which resulted in the rapid decreasing of the mangrove resource. The land use trend would not change much. The problems in this area come from the conflict between the characters of natural structure and the settlements along the canals resulted in land use and land subsidence. To solve these problems, we have to pay more cost. Because the area is an urban area which has high density of residents and many factories whereas without a wastewater treatment plant. The conclusion of this study is to main aquatic farm which are suitable in this study area based on the natural ecology system and this area, Bua Pan community is suitable for the orchard farm. The land use of this area should be the rural and agricultural area for aquatic farm and orchard farm. That means the government agencies have to pay more attention to improve the facilities and utilities to the selected community centers. Mangrove areas should be conserved. To fulfill the target achievement, it is needed to formulate the measures for promoting and controlling this area in accordance with the potential land use.
