Abstract: This study chose the middle and southern mountainous region of Shandong province and took Tai'an City as a case study. Index system of land eco-environmental status evaluation was constructed. The land eco-environmental information was extracted from the TM images by remote sensing technique, evaluation method was adopted combining RS and GIS technique, evaluation was conducted by land eco-environmental status index (EI) model, and dynamic change was completed by comparison results of the two period evaluations. The results show that the land eco-environmental status in Tai'an City was generally good in 2005. The area of the excellent grade is 14.34% of the total area, that of the good grade was 39.19%, the common grade was 12.40%, the worse grade was 15.61% and the worst grade was 18.46% of the total area. Compared with that of 1987, the land eco-environmental status had a meliorate trend. Based on the analysis of the various land categories in Tai'an City, the land eco-environment protection measures were advanced. Land eco-environmental status evaluation methods were explored which combined RS and GIS technique, and the regional land eco-environment status and the variation trend were analyzed; therefore, this study has noticeable significance to the regional land eco-environment protection and its improvement.
