Analysis of the Ecological Environment Change by Geoinformatics Technology at Special Erosion Area in Taiwan
Due to the poor condition of soil and micro-climate condition,the mudstone area in the southwestern Taiwan has been difficult for plants to grow.The area is always in such a bare condition that it is nicknamed Moon World. Serious erosion and natural disasters in the mudstone area are the significant problems for soil and water conservation,and the area of bald mudstones is expanding.Statistical data show that bare area has increased 3 times during the past 10 years.The mudstone area in the southwestern Taiwan was hard to plant and then it always in bare condition which got a nickname of The Moon World.The distribution of each land-use type in mudstone area,and spatial information in years were integrated into GIS by ArcView.In the respect of ecosystem,ecological index in different periods were calculated based upon landscape ecological theory.To explain its meanings and the danger behind the bare mudstone area,the results indicated that mosaic gathering was caused by mudstone and thorn bamboo.The results illustrated that the ecological factor of landscape such as patch shape factor,and Shannon evenness factor that have significant canonical correlation with water qualities and erosion of the study area.In study area,there are many styles of fracture,variation,and mosaic distribution landscape.
