Xi'an Land Use/Cover Change and Ecological Effect Evaluation Studies
利用1988和2000年遥感影像，分析了西安土地利用/覆盖变化，并计算了由此引起的生态效应变化，发现建设用地急剧增长，生态系统服务价值下降。
Using Xi'an 1988,2000 two years remote sensing image,according to the geoscience information atlas theory and the terrestrial space information cognition theory,take ARCGIS9.0 and ERDAS8.5 as the platform have analyzed the Xi'an during 1988-2000 years land use space and time variation process;And calculated the ecological effect change caused by LUCC in 1988-2000;The result indicated: during 12 years Xi'an city land use/covering change is fierce,the comprehensive land dynamic degree is 3.5%,construction land area sharp growth,the year rate of change achieves 261.1%;The Xi'an city ecosystem service value reduces during 12 years from 306.7×106 Yuan to 259.8×106 Yuan,altogether reduced 46.9×106 the Yuan;This article proves with the 3S method study the land use/cover change caused by the ecology response is one effective method.
