贵州省毕节市区域地质构造特征及矿区地质环境治理研究

Study on karst geological structure characteristics and rocky desertification protection in Bijie City,Guizhou Province

贵州省毕节市地区作为矿产资源大区,矿产经济在区内社会发展和经济增长方面占据了重要地位。但因其区域内碳酸盐岩易溶易风化,各类地貌发育,部分地区的表层存在土壤流失的现象。我们通过对其区域内典型的织金溶洞等三大地貌单元的形成演化过程进行探讨,确定了其演化序列和成因。在矿产经济的发展治理中应注意扬长避短,以水土流失综合治理为核心。

Bijie City,Guizhou Province,as a large area of mineral resources,plays an important role in social development and economic growth.However,due to the fact that the carbonate rocks in the area are easy to be dissolved and weathered,and all kinds of landforms are developed,there is a phenomenon of soil loss on the surface of some areas.We discussed the formation and evolution process of the three geomorphic units,such as Zhijin karst cave,and determined the evolution sequence and genesis.In the development and management of mineral economy,we should pay attention to the advantages and avoid the disadvantages,and take the comprehensive control of soil and water loss as the core.
