| 摘 要： | 基于地理信息系统(GIS)和多级模糊模式识别模型,建立了略阳县空间数据库和地质环境质量评价模
型;综合考虑地形坡度、工程地质岩组、岩土体结构类型、地下水位、植被发育情况、月平均降雨量、人类工程活动
强度等因素,用层次分析法确定各指标权值,应用评价模型对略阳县地质环境质量进行了综合评价,把略阳县地
质环境划分为优、良、中、差4个质量级别。

| Abstract: | Based on GIS and the model of multi-class fuzzy pattern recognition, the spatial database in Lueyang
county and geoenvironmental quality assessment model are established. By considering such factors as terrain
slope, engineering geological rock groups,structural type of rock and soil mass,ground water level, vegetation
growth conditions, monthly precipitation, intensity of human engineering activities, the geoenvironmental quality
in Lueyang county is assessed comprehensively with the assessment model. The geoenvironment quality is classi-
fied into four classes: best, good, moderate, and worst. The assessment result can provide rational plan and ref-
erence basis for the prevention and control of geological hazards and the protection of ecological geoenvironment. |
