摘要
浙江湖州及邻区地貌总体特征是以平原为主 ,丘陵次之。本文在讨论了影响区域地貌发育因素的基础上 ,对平原区和丘陵区的次级地貌单元进行了划分并作了总结。详细分析了区内不同地貌单元下存在的原生和受人类经济活动影响出现的环境地质灾害问题 ,指出原生地质 -地貌条件下区域环境地质问题 (如地壳稳定性、软土地基、地下水水质、土壤渍害、水土流失等 ) ,大多对人类社会影响不大或者已经有了相应的防治对策 ;但是 ,受人类经济活动影响 ,人为的或人工诱发的环境地质问题则越来越严重 ,如平原区由于过量开采地下水出现的地面沉降 ,丘陵区由于开采石矿引起的景观破坏、水土流失、岩溶塌陷和滑坡等地质灾害。
Geomorphology is mainly characterized by plains, hills in the next in Huzhou and its neighboring areas, Northern Zhejiang Province. On the basis of the regional geomorphology, the secondary morphologic units of plain and hill areas are divided and summarized in this article. In succession, the primary hazard problems of environmental geology and those caused by the influence of human being's economic activities in the regional different geomorphic units are also analyzed in detail. The authors point out that in the primary geologic-morphologic conditions most of the regional environmental problems, such as crust stability, foundation of soft soil, water quanlity of ground water, soil waterlogging, water and soil loss etc. have small effect on human being's society, and some related countermeasures of prevention and cure have been adopted. But man-made or artificial inducing environmental geological problems are even more and more severe, for example, land subsidence occurrence as a result of the superfluous exploitation ground water in plains, landscape destruction, water and soil loss, karst collapse, landslide caused by mining stone deposits in the hills and so on.
