摘要
我国典型溶蚀丘陵型岩溶发育区主要分布于湘中的新化县 -涟源县一带。受中国大陆梯级地形、复杂地质背景、气候水文等内外环境因子的联合作用 ,发育了一系列独具特色的不同类型的岩溶地貌及形态组合。宏观岩溶地貌主要有四种类型 :丛丘谷地、丘岭谷地、峰丛洼地谷地和峰丘谷地。不同单元岩溶发育特征差异明显。溶蚀速度在10 .2 6～ 30 .0 4 m3 / km2 · a,总体上侵蚀作用大于溶蚀作用 ,以流水溶蚀-侵蚀形态为主导特征。开发利用岩溶水应从地貌差异和岩溶水系统多层多块结构特点出发 ,因地制宜 ,蓄、引、提、堵等多种开发方式相结合。
In China,the typical corrosional hill regions mainly distribute in the central part (around Xinhua,Lianyuan counties) of Hunan province. Under the joint effect of step like continental topography,complicated geological setting,climate and hydrology,etc.,a series of karst landforms,and karst feature complex with distinctive features are well developed in this area. Macroscopic karst landforms can be divided into four types: cluster hill,ridge hill,peak cluster,and peak hill. And there are remarkable differences in varied morphological units with the corrosion rates ranging from 10 26 m 3/km 2·a to 30 04m 3/km 2·a. According to the geomorphological differences,and the multi layer and multi unit structures of the karst water systems, the karst water exploitation should be made by the combination of diversified ways, such as reservoir, channel, pumping, drainage, pounding.Small scale projects should be considered with scatting distribution. Effects should be made to conduct water by self flowing way, and for project's sustainable operation.
