ABSTRACT

 

The study of relationship between climatic factors and forest area has been conducted at Huay Sai Royal Development Study Center, Petchaburi Province Thailand and it vicinity area. The changing of forest area of the site was analyzed by interpreting satellite image taking by Lansat-5 TM in 1990, 2000 and 2010. The climatic factors data e.g. temperature, rainfall, relative humidity in 30-year period (1981-2011) and average evaporation in 29-year period (1982-2011), was collected from the adjacent weather station. The correlation test between each climatic factor and between climatic factors and the forest area were applied in order to investigate their relationship. Moreover, the simple linear regression analysis was applied in case of their relationship show statically significant. According to the analytical results, it discovered that the changing of forest area surrounding Huay Sai Royal Development Study Center has impacted to rainfall, temperature and evaporation. The increasing of forest area induces the rising of rainfall and the reduction of temperature and evaporation. Nevertheless, the changing of forest area does not affect directly to relative humidity.
