| Abstract | This research is an attempt to develop and evaluate a methodology for assessing the land use analysis the land use changed, land misused, and watershed classification. And distinguish between areas to be permanently protected as forest watershed cover, and areas open for utilization of all resources or conversion to agronomic uses of the study area for a representative watershed area of Huai Sia watershed in the southwestern part of the Central Section of Thailand. By integrating remote sensing and GIS technology. Digital elevation model and slope data are combined with remotely sensed satellite data in image processing and dynamic analysis of land use of the agroecosystem landscape of the watershed and trend to environment change of 1987 to 1997. GIS using ARC/INFO software and ARCNIEW3 do land misused and watershed classifications in the research 2 software as the tools in land classification. The result show that during the period of ten years, dramatic land uses change took place resulting from population increase, mismanagement, and land misused. Agricultural area expanded to the high elevation area and steep slope at the expense of losing forest area. The most important change in the study area is conversion of upland crops into bars soil and grassland. The results also show that major area of farm was used for upland crops, paddy field, and mixed orchard in not suitable area at Huai Sai watershed, sustainable agriculture and natural resources management is needed. The method developed which has been applied for mapping watershed classes based on the best, currently available data for the factor; soil texture, effective soil depth, soil drained, slope, elevation, geology, effective rainfall, and land use. Watershed classes map is produced efficiently by personal computer. It cloud be anticipated that, the watershed classification regulation would contribute to long term benefits to water resources development and sustainable watershed development project if it cloud be efficiently implemented throughout the area. |
