In recent years, due to human excess demand for geological resources and urban sprawl , causing human and geological environment increasingly acute contradictions between the various geological disasters exacerbated . Therefore , to carry out the evaluation of the quality of the geological environment , construction area suitability assessment study on the urban construction projects to ensure the safety and security of life and property , has a very important significance. In this paper, lueyang urban geography and geological environment ( including natural and geographical conditions , geological and geomorphological conditions , geotechnical conditions , hydrogeological conditions, etc. ) , based on analysis of the first lueyang urban environment geological disasters , the main research contents include: active faults and the effects caused by the disaster , earthquake and disaster effects , high-risk slopes , landslides, mudslides caused by the effects of disasters , human engineering - economic activities and effects caused by such disasters ; Secondly, a lueyang urban geological environment quality evaluation system and evaluation model , the use of sensitive factor - fuzzy comprehensive evaluation method lueyang urban geological environment quality was evaluated ; once again established lueyang city construction site suitability evaluation system and evaluation model, using the neural network method to evaluate the lueyang urban construction site suitability ; Finally, an lueyang urban strategies and sustainable future environmental geological disaster prevention countermeasures.
