| Abstract | This study aims at understanding land use and land cover change in Quang Nam -a coastal province in term of effect by climate conditions for the period 1990-2009. It applied Remote sensing technology and GIS to design the maps of land use and to quantify land use change from Landsat TM, ETM+ satellite images for time frame between 1990 to 2009.The analysis of data within this study was accomplished through integrated use of ERDAS imagine (version 9.2), ArcGIS (version 9.3) and SPSS v.17 software packages along with Microsoft office analytical tools. The findings reveal significant decrease in forest land from 27% to 21.8% and in open land from 9.9% to4.0%; whereas the increase is recognized in built-structures from 19.8% to 29.5% and agricultural land especially paddy land from 26.2% to 28.0% by the year of 1990 and 2009. The changes in climate factors including rainfall, temperature and natural hazards are visible at this study site. Average annual temperature and rainfall tend to increase over time standing at ±1°C and 500-700mm respectively. The frequency of natural hazards such as tropical cyclones, flood and drought is increasing over time, especially these years. The result of Principal Component Analysis (PCA) with Varimax with Kaiser Normalization Rotation Method on the relationship between 8 climate factors (min, max and mean temperature, rainfall, evaporation, humidity, hours of sunshine, wind speed) and areas of 10 crops (annual paddy, winter-spring paddy, summer-autumn paddy, spring-summer paddy, corn, sweet potatoes, cassava, sugar-cane, peanut, and aquaculture) reveals significant correlation between these climate factor sand crops land. The findings of this study can be useful for local people and decision makers who look for an appropriate solution in land use management. |
